Quick answer

Goldcattle supplies custom metal gearcase and motor housing components for power tool OEMs from engineering drawings. The metal group covers split gearcase bodies, motor end housings, bearing supports, gearbox covers, spindle housings and mounting plates. These parts carry bearing bores, gear shaft positions, motor mounting faces, sealing interfaces and fastener bosses. Plastic outer shells and grips are a separate injection-molding route. Metal housings can be CNC machined from billet for prototypes and low volumes, or die cast near-net-shape and finish-machined in CNC. Route, material and tolerance are confirmed after drawing and assembly review, not assumed from the keyword alone.

What a Power Tool Housing Must Do Inside the Tool

A handheld power tool separates into two housing groups that buyers should not mix in one quotation. The metal gearcase and motor housing is the structural load path: it locates the bearings, holds the gear shafts at their designed center distance, seats the motor, and provides the split faces, bosses and fasteners that hold the assembly together. The plastic outer shell and grip provides external form, hand contact and isolation, and is normally produced by injection molding rather than CNC cutting.

The metal group is where alignment, rigidity and sealing matter. A bore that drifts position changes gear mesh; a mating face that is not flat affects split-line sealing; a boss that fails under repeated assembly loosens the cover. This page focuses on those metal functional housings and the matching precision components, with the plastic shell covered as a coordinated manufacturing capability rather than a second product catalog.

Goldcattle has manufactured metal and plastic components since 1998 and works under an ISO 9001:2015 quality system. Related capability pages cover precision CNC machining services, custom aluminum and magnesium die casting, custom plastic injection molding, and integrated metal and plastic manufacturing under one BOM and tolerance review.

Power Tool Housings and Components We Manufacture

The component list below follows function inside the gear train and motor interface, not a generic enclosure category. Each family is reviewed against the assembly drawing, bearing arrangement and required fit.

Gearcase Housings

Split or single-body metal cases that enclose the gear train, carry bearing bores, gear shaft positions and split-line mating faces, and connect to the motor side.

Motor End Housings

End covers and stator-side housings that locate the motor, provide the mounting face and hole pattern, and close the gearcase at the motor interface.

Bearing Supports

Bearing seats and carrier structures that hold the bearing outer ring, transfer load into the housing wall or rib, and keep the shaft axis aligned with the gear train.

Gearbox Covers

Removable side and end covers with sealing faces, fastener bosses and access features, machined to match the mating housing split line.

Spindle Housings

Housings around the output spindle or quill, carrying the output bearing seat, drive interface and mounting geometry for the tool head.

Motor Mounts

Mounting brackets and interface plates that fix the motor to the gearcase, with hole positions, locating features and load-bearing bosses.

Bearing Carriers

Rotational or plate-type carriers that position one or more bearings, often produced by turning combined with milling and drilling.

Mounting Plates

Interface plates and flanges that connect the housing to adjacent assemblies, with drilled hole patterns, dowel locations and flat mating surfaces.

Power Tool Applications

Metal housing requirements vary by tool type because the gear train, motor load and grip layout differ. The descriptions below cover the housing structure, not the finished tool.

Cordless Drills

Drill gearcases carry the drill gear train, motor seat and chuck-side output bearing. Bore alignment and split-face flatness control gear mesh and cover fit under repeated tightening.

Impact Wrenches and Drivers

Impact tool housings must hold the drive shaft and bearings against torque reaction, with rigid bosses and ribs around the bearing seat and fastener locations.

Angle Grinders

Grinder gearcases connect the motor axis to the output spindle through an angled gear pair, so shaft center distance, bore position and mating face flatness are reviewed against the bevel gear arrangement.

Rotary Hammers

Rotary hammer housings combine gear reduction with impact mechanisms; bearing supports and bosses are sized for vibration and impact loads specified on the assembly drawing.

Manufacturing Route Selection: CNC Billet, Die Casting or Injection Molding

Not every power tool housing should be CNC cut from solid stock. The route follows design maturity, geometry, annual volume and target cost. CNC machining covers billet parts and finish work; die casting forms near-net metal structures; injection molding produces the plastic shell and grip. The manufacturing services overview lists the combined capability base.

Evaluation factor	CNC billet machining	Die casting plus CNC	Injection molding
Design change frequency	Suits frequent revisions; no forming die to modify	Geometry should be stable before die investment	Geometry should be stable before mold investment
Initial tooling	No forming die; fixture and programming required	Die casting die plus CNC fixtures	Injection mold plus any metal inserts
Complex ribs and features	Limited by tool reach and cutter access	Near-net ribs, walls and bosses in the casting	Complex plastic ribs and undercuts in the molded part
Critical bores and mating faces	Machined directly to final tolerance	CNC finishes bores, faces and threads after casting	Uses molded control, inserts or post-machining where required
High-volume economy	Material removal limits per-piece cost at volume	Usually more favorable for stable metal production	Usually more favorable for stable plastic production
Typical object	Metal prototypes and low-volume housings	Production metal gearcases and end housings	Plastic outer shells, grips and covers

Materials for Metal Housings and Plastic Shells

Metal and plastic selection follows different logic. The metal housing is chosen for rigidity, weight, load path and machining or casting behavior; the plastic shell is chosen for impact, appearance, grip and molding behavior. The grade is confirmed against the operating condition, not copied from another tool model.

Part group	Material candidates	Selection focus
Metal gearcase	Aluminum die-cast alloys	Structural rigidity, weight balance and available machining allowance on casting features
Lightweight metal housing	Magnesium AZ91D, AM60B	Weight reduction and impact behavior; corrosion condition reviewed against exposure environment
CNC prototype housing	Aluminum 6061-T6	Prototype development, machinability and readily available billet
High-strength CNC part	Aluminum 7075-T6	Higher strength requirement where the environment and cost support the grade
Bearing support insert	Steel, stainless steel	Hardness, bearing fit and wear resistance at the contact surface
Plastic outer shell	ABS, PC/ABS	Impact resistance, appearance and molding behavior
Reinforced tool body	PA6, PA66 with glass fiber	Strength and stiffness; moisture and dimensional change considered in design
Grip and soft touch	TPE, TPU	Hand contact, wear and bonding or overmolding arrangement

Material substitution, recycled content and supplier-grade changes require written approval after review of the drawing and required properties. Where a housing pairs a metal insert with a molded body, galvanic and thermal interaction between the two materials is checked in the design review.

Critical Engineering Requirements for Gearcase Housings

The nine requirements below are the features a power tool OEM typically audits on a metal housing. They describe what must be defined on the drawing and what the supplier checks; each project sets its own acceptance values.

Bearing

Bearing Bore Accuracy

Bore diameter, roundness, seat surface condition and the fit against the bearing outer ring. A bore that runs loose or off-center affects shaft position and bearing life.

Alignment

Gear Shaft Alignment

Shaft center distance, bearing bore position, coaxiality and runout between axes, checked against the gear pair and backlash requirement.

Motor seat

Motor Mounting Geometry

Stator seat, mounting face, hole pattern, concentricity and axial position that sets rotor clearance relative to the gear train.

Sealing

Mating Face Flatness and Sealing

Split-line flatness, gasket or O-ring groove geometry, contact width and fastener location that hold grease and keep dust out of the gearcase.

Fasteners

Fastener Boss Integrity

Threaded holes, press-in inserts, screw bosses and pull-out resistance sized for repeated assembly and disassembly during service.

Thermal

Thermal Management

Cooling fins, vent openings and material heat transfer around the motor and gear train; thermal distortion between datums is considered in the machining review.

Loads

Vibration, Impact and Torque

Rib layout, wall sections and boss support against vibration, impact and torque reaction from the tool duty cycle specified in the assembly review.

Rigidity

Weight and Rigidity

Balance between housing weight and structural stiffness, reviewed with rib geometry, wall sections and load paths rather than material density alone.

Finish

Finishing and Corrosion Protection

Coating choice, masking of fit surfaces, coating thickness control and corrosion protection matched to the material and exposure condition.

CNC Processes Used on Power Tool Gearcases

Housings are prismatic parts with rotational bearing and shaft features. The process mix follows the geometry and datum plan set after DFM review; a part does not automatically require five-axis machining.

Milling

CNC Milling

Mounting faces, pockets, ribs, flats, slots and contoured edges on the housing body, cover and mounting plate.

Boring

Boring and Reaming

Finish sizing of bearing bores and gear shaft holes, controlling diameter, roundness and seat condition against the drawing tolerance.

Threads

Drilling and Threading

Mounting holes, boss holes, tapped threads and thread-milled features, with thread inspection where the drawing requires it.

Multi-axis

Multi-Axis and Turning

Four- or five-axis work for multi-face access and angled features; turning for bearing carriers, spacers, adapters and other rotational components. Five-axis capacity is covered in the 5-axis CNC machining services page.

CNC Post-Machining of Die-Cast Housings

A casting is a near-net blank, not a finished gearcase. The rough casting leaves walls and ribs close to final shape, but bearing bores, mating faces, holes and threads usually need CNC finish machining to reach assembly tolerance. The sequence below follows a typical die-cast housing program; the exact steps are set against the drawing and casting allowance.

Raw casting inspection: check the blank for defects, wall condition and leftover allowance before it enters machining.
Datum establishment: choose and machine the reference datums that subsequent setups and measurements will use.
Fixture design: build the holding concept around the casting features, avoiding clamping stress near bearing bores and sealing faces.
Bearing bore machining: rough and finish the bearing seats to diameter, position and surface condition.
Gear shaft hole machining: machine the shaft holes to center distance, coaxiality and perpendicularity requirements.
Mating face machining: finish split faces and mounting faces to flatness and seal contact requirements.
Threading and tapping: cut internal threads in bosses and check thread form and engagement.
Deburring and cleaning: remove burrs from bores, threads and edges, and clean chips from internal passages.
Surface finishing: arrange conversion coating, anodizing, painting or other finish, with fit surfaces masked or allowance protected.
Final dimensional inspection: verify critical bores, positions, threads and faces against the inspection plan before release.

Tolerance Tiers Applied Feature by Feature

Tolerance is set on each feature according to its function. The project does not carry a blanket tight tolerance across every wall, edge and hole; general features follow the drawing, and only location-critical features move to the tighter tiers.

General

Per drawing

Non-critical walls, outer contours and cosmetic features follow the drawing and general tolerance block agreed at review.

Precision

±0.01 mm

Mating faces, mounting hole patterns and bearing seats that require controlled fit and position are reviewed to precision tolerances such as ±0.01 mm where the drawing calls for it.

Tight

±0.005 mm qualified

Tighter ±0.005 mm features are reviewed case by case for feasibility, measurement method and fixture stability; they are not promised on every bore or face.

Bearing bores, center distance and coaxiality carry the tightest functional requirements in most gearcases. Whether a ±0.005 mm feature can be held depends on datum stability, fixture rigidity, machine capability and inspection access; these are assessed before the tolerance is committed to a quote.

Surface Finishing and Corrosion Protection

Finishing is selected for the material and the exposure condition, with fit surfaces planned ahead of coating. Bearing bores, gear mating faces and sealing grooves must either be masked or carry finish allowance, because coating thickness changes fit and seal contact.

Aluminum: anodizing, conversion coating, powder coating or painting, chosen against appearance, wear and corrosion requirement.
Magnesium: conversion coating or approved protective coating, reviewed for the exposure environment and compatible fastener materials.
Steel inserts: zinc plating, black oxide or painting, with thread and bore protection arranged per part.
Plastic parts: mold texture, painting, laser marking or other finish defined on the plastic drawing.

CNC machining, die casting and injection molding are handled in-house; some special coatings are arranged through qualified partner suppliers and managed against the project quality agreement. The in-house versus partner split is confirmed at RFQ so the buyer knows who performs each finish step.

Dimensional Inspection and Assembly Validation

Inspection follows the drawing and the agreed inspection plan. The first-article check verifies critical features before repeat production; in-process checks watch setup and key features during the run; final inspection confirms bores, fits, threads, mating faces and surface condition before release.

Bore and seat checks
Bore diameter, roundness and seat condition checked with bore gauges and micrometers.

Position and geometry
Position, coaxiality, perpendicularity and center distance checked on a CMM where required.

Threads and fits
Threads checked with thread gauges against the drawing specification; assembly fit verified against bearings, shafts and mating covers where the programme calls for it.

Validation scope
Drop, vibration, endurance, torque, thermal and corrosion tests are whole-tool-level or project-specific validations arranged against the customer test scheme and equipment.

Quality documents available on request

Material certificate or material declaration per part number
Dimensional inspection report with measured critical features
First-article inspection (FAI) where requested
Coating specification and RoHS / REACH documentation where applicable to the project

Compliance wording to keep in scope

IEC 62841 is a power tool safety standard series applied at the whole-tool level. The housing supplier follows the customer drawing, test plan and quality agreement; the part itself does not carry IEC 62841 certification. RoHS and REACH statements are provided on a project and material basis, not as a whole-tool declaration.

Quantities and Project Stages

Prototype, pilot and repeat-production parts are reviewed against the same drawing revision. The stage changes which route and cost structure fit, not which inspection standard applies.

Prototype

Single parts or small sets to validate geometry, bearing fit and the fixture concept before production. Usually CNC billet for metal housings.

Pilot

Pilot batch

A small pre-production run that confirms the machining or casting process, inspection method and repeatability before scheduled batches.

Production

Repeat production

Scheduled batches after approval, with die casting plus CNC for stable metal housings and injection molding for stable plastic shells.

Small batches carry setup, programming and fixture costs spread over fewer pieces; larger volumes amortize those costs across more units. Die and mold investment suits stable, higher-volume geometry. State the project stage and expected annual volume in the RFQ; capacity and timing are confirmed after drawing review.

Frequently Asked Questions About Custom Power Tool Housings

What are custom CNC power tool housings?

Custom power tool housings are the structural metal and plastic parts that enclose and support the motor, gear train, bearings and output shaft of a handheld power tool. The metal group includes split gearcase bodies, motor end housings, bearing supports, gearbox covers, spindle housings and mounting plates. These parts carry bearing bores, gear shaft positions, motor mounting faces, sealing interfaces and fastener bosses. The plastic group covers outer shells and grips produced by injection molding. Metal housings can be CNC machined from billet for prototypes and low volumes, or die cast near-net-shape and then finish-machined in CNC. Each part follows the customer drawing, assembly drawing and agreed inspection plan.

Can one manufacturer produce both the metal gearcase and the plastic outer shell?

Yes, when the project requires both. Goldcattle coordinates CNC-machined and die-cast metal components with injection-molded plastic parts under one BOM and one tolerance review. The metal gearcase and the plastic shell perform different jobs: the metal part locates bearings, shafts and the motor and carries load paths, while the plastic shell provides external form, grip and isolation. The two interfaces must be checked together, including locating features, screw bosses, vent openings and fit clearances. A combined review compares the metal datum, the molded boss position and the assembly stack-up before tooling or production is committed. If the project needs only the metal housing, the plastic side can be handled separately.

What materials are used for power tool gearcase housings?

Metal gearcases are commonly reviewed in aluminum die-cast alloys for rigidity and weight balance, and magnesium alloys such as AZ91D and AM60B where lightweight impact performance is the design target. CNC prototype and high-strength parts may use aluminum 6061-T6 or 7075-T6 from billet. Bearing support inserts and wear surfaces can use steel or stainless steel. Plastic outer shells use ABS or PC/ABS for impact and appearance, PA6 or PA66 with glass fiber for reinforced bodies, and TPE or TPU for soft-touch grips. The grade is chosen against load, temperature, corrosion condition, weight and molding or machining behavior. Material supply and condition are confirmed before production, and substitution requires written approval.

Is a power tool housing CNC machined from solid billet or die cast?

Both routes are used, and the choice follows design maturity, geometry and volume. CNC billet machining suits prototypes, low volumes and designs that still change, because it needs no forming die and can machine bores, faces and holes directly. Die casting plus CNC suits stable metal gearcases in mid and high volumes: the casting forms ribs, walls and bosses near net shape, and CNC finishes bearing bores, mating faces, holes and threads. Injection molding handles the plastic shell and grip at high volume. Do not assume every housing is cut from solid stock. For a new tool design, billet prototypes validate fit before a die is committed; for a stable production part, the casting plus post-machining route usually reduces metal removal and per-piece cost.

How are bearing bores machined and controlled in gearcase housings?

Bearing bores are the critical location features in a gearcase. Machining follows the established datum: rough bore, semi-finish, then finish boring or reaming to the drawing diameter, roundness and surface condition. The bore is checked with a bore gauge, internal micrometer or pin gauge, and position and perpendicularity are measured on a CMM where the drawing requires it. A bearing seat is not judged by diameter alone; the coaxiality between bores, the bore position relative to datums and the fit against the bearing outer ring all affect shaft position and gear mesh. Finish allowance and clamping support are set in DFM, and the measurement method must match the tolerance claimed on the drawing.

How do you control gear shaft alignment and center distance?

Gear alignment depends on the position of each bearing bore, not on a single bore dimension. The drawing defines the shaft center distance, bearing bore positions, datum references and allowed runout or parallelism. During machining, the fixture locates the part on stable datums so successive setups keep the same reference frame. Finished bores are measured for position, coaxiality and perpendicularity, and center distance is verified against the gear pair specification. If the assembly drawing lists gear backlash or mesh condition, the housing geometry is checked against that requirement before release. Early review of the gear arrangement helps set the datum plan, fixture concept and inspection method, so alignment targets are achievable before tooling is cut.

What motor mounting geometry must be specified on the drawing?

The motor interface should state the stator seat diameter and tolerance, the motor mounting face and its flatness, the mounting hole pattern and positions, concentricity between the seat and the mounting face, and the axial position that sets rotor clearance. Where the housing locates the motor relative to the gear train, the drawing should reference the shared datum and any required runout between the motor axis and the gear shaft axis. Include the mating motor end or its drawing so the fit can be checked against the real interface. These features are finish-machined after the casting or billet datum is established, and inspected against the agreed measurement method. Missing motor dimensions are a common reason for a quote to be held open.

Which CNC processes are used on power tool gearcases?

Prismatic housing features are produced by CNC milling: mounting faces, pockets, ribs, flats and contoured edges. Boring, reaming and drilling prepare and size bearing bores, gear shaft holes and mounting holes. Tapping or thread milling produces internal and external threads in bosses and covers. Turning is used for related rotational components such as bearing carriers, spacers and adapters. Four- or five-axis machining is selected where multi-face access or angled features require it; not every gearcase is a five-axis part. The route follows geometry and datum plan after DFM review. On die-cast parts, the CNC step finishes the features the casting leaves at near-net shape, including bores, mating faces and threads that need final tolerance.

What surface finishes apply to aluminum and magnesium housings?

Aluminum housings may be anodized, conversion coated, painted or powder coated according to the drawing and corrosion condition. Magnesium typically uses a conversion coating or approved protective coating, selected against the exposure environment. Steel inserts may receive zinc plating, black oxide or painting, and plastic parts use texture, painting or laser marking. Bearing bores, gear mating faces and sealing faces need masking or finish allowance planned before coating, because coating thickness changes fit and seal contact. Adhesion, coating thickness and galvanic compatibility are reviewed for the material pair. Some treatments are arranged through qualified partner suppliers rather than performed in-house, and the finish scope is confirmed at RFQ.

How are power tool gearcase parts inspected and validated?

Inspection follows the drawing and agreed inspection plan. A first-article check verifies dimensions and critical features before repeat production; in-process checks watch setup and key features during the run; final inspection checks bores, fits, threads, mating faces and surface condition before release. Measurement tools match the feature: bore gauges, micrometers, thread gauges and CMM for position and geometry. Assembly fit verification checks the housing against bearings, shafts and mating covers where the programme requires it. Drop, vibration, endurance, torque, thermal and corrosion tests are whole-tool-level or project-specific validations arranged against the customer test scheme; they are not assumed to be performed in-house. Confirm which tests and records the RFQ requires.

What quantities do you accept for power tool housing projects?

Prototype, pilot and repeat-production quantities are all reviewed from the same drawing revision. A prototype is a single part or small set used to validate geometry, bearing fit and fixture concept before production. A pilot is a small pre-production batch confirming the process, inspection method and repeatability. Repeat production covers scheduled batches after approval. Small batches carry setup, programming and fixture costs spread over fewer pieces, while larger volumes amortize those costs across more units. Die casting and injection molding carry forming die or mold investment that suits stable, higher-volume parts; CNC billet avoids that tooling but costs more per piece at volume. State the project stage and expected annual volume in the RFQ; capacity and timing are confirmed after drawing review.

What information should a power tool housing RFQ include?

Send the 3D model in STEP, STP, IGES, X_T, DWG or PDF where available, plus the 2D drawing with revision, datums and GD&T. Include the gearbox assembly drawing, bearing specifications, shaft center distance, motor interface and required torque or speed conditions. State the material or alloy, annual volume by stage, surface finish, and any vibration, drop or corrosion requirements. List inspection criteria, critical-to-quality features, delivery condition (raw casting, machined housing, finished housing or subassembly) and packaging requirements. A model alone cannot define tolerance and fit; the drawing carries those. The more complete the package, the closer the first quote matches the production housing and its inspection method.
