✅ High speed steel grade resists dulling during hard cuts
✅ Tapered lead angle pulls easily through pre machined holes

💡 What makes a manual keyway broacher actually stay sharp during repeat shop runs?
Keeping that edge intact boils down to steel hardness, flute geometry, and how you manage chip evacuation on the bench.
- Run a light oil based coolant to wash swarf away from the cutting lips
- Take shallow progressive passes so the full length shares the cutting load
- Store the tool in a dry rack to quit rust from attacking the precision bore
