Precision Broaching Service for Keyways, Splines and Internal Profiles
Custom broaching solutions for keyways, splines, internal profiles, hex holes, square holes and precision OEM metal components.
When Broaching Is The Most Efficient Manufacturing Solution
Broaching is often selected when components require internal profiles, keyways, splines or non-round holes that are difficult or inefficient to produce with milling or turning.

Broaching Capability
| Processes | Internal broaching, surface broaching, rotary broaching |
|---|---|
| Applications | Keyways, splines, internal profiles, polygon holes |

| Inspection | FAI, CMM, final inspection |
| Files | STEP, STP, IGES, DWG, PDF |
Materials We Process
Material selection, hardness and feature geometry are reviewed before broaching to confirm the most stable production route.
When Is Broaching Better Than Milling?
| Requirement | Broaching | Milling |
|---|---|---|
| Keyway Production | Excellent | Moderate |
| Production Speed | Excellent | Moderate |
| Repeatability | Excellent | Good |
| Low Volume Production | Moderate | Excellent |
| Custom Shapes | Good | Excellent |
Broaching is highly efficient for repetitive production of keyways, splines and internal profiles, while CNC milling is more flexible for low-volume custom geometries.
Broaching Or Wire EDM?
| Requirement | Broaching | Wire EDM |
|---|---|---|
| Production Volume | Excellent | Moderate |
| Cycle Time | Fast | Slower |
| Internal Profiles | Excellent | Excellent |
| Tooling Cost | Higher Initial Cost | Lower Setup Cost |
| High-Volume Production | Excellent | Moderate |
For very fine profiles or low-volume conductive materials, Wire EDM may be a better route. For repeat production, broaching usually provides faster cycle time.

Broaching FAQ
Concise answers for process fit, profiles, materials, production volume and inspection.
What is broaching?
Broaching removes material with a shaped tool to create repeatable profiles in one controlled pass.
What is keyway broaching?
It produces straight key slots in hubs, gears, couplings and transmission components.
Can you produce internal splines?
Yes. Internal spline feasibility is reviewed from geometry, tolerance, material and volume.
What materials can be broached?
Carbon steel, alloy steel, stainless steel, aluminum, brass and copper alloys.
When choose broaching instead of milling?
Choose broaching for repeat keyways, splines and internal profiles where speed matters.
Can broaching be used for high-volume production?
Yes. Broaching is especially efficient for repeat production after tooling is validated.
Do you provide inspection reports?
Yes. FAI, CMM and final inspection records can be provided when required.
What CAD formats do you accept?
STEP, STP, IGES, DWG and PDF with material, tolerance and quantity notes.
