8mm C HSS Keyway Broach Push Type Metric Size High Speed Steel Keyway Cutting Broaching Tool For CNC Router And Machining Projects Heavy Duty Metalwork Accessory

8mm HSS Keyway Broach Push Type for CNC Machining
✔️ Heavy-duty HSS tool with large broaching allowance and multi-tooth

The keyway broach is designed to cut internal keyways inside bore holes. It’s widely used in machining, batch production, automotive parts manufacturing, and other metalworking projects, especially where high efficiency and precision are needed.

✅ 8mm metric size HSS keyway broach for inner-bore keyway cutting
✅ Large broaching allowance and multi-tooth design for efficient machining
✅ Made of high-hardness, wear-resistant HSS tool steel
✅ Correct installation and firm clamping to prevent loosening during broaching
✅ Suitable for machinery manufacturing and automotive parts production

💡 What is a keyway broach used for in machining?

Here's a handy, general explanation to guide your decision:

• Keyways are machined into bore surfaces to transmit torque between parts.
• Push-type broaches speed up production with precise, consistent cuts.
• High-speed steel provides rigidity and wear resistance for repeated use.
• Proper alignment and secure clamping prevent broach drift during operation.
