Questions about this product
- What specific thread sizes can I create with this tap drill set?
- This six-piece set includes metric sizes M3, M4, M5, M6, M8, and M10. Each bit drills the exact pre-hole needed for perfect thread engagement. They are designed specifically for metric thread standards in metalworking projects.
- What are the temperature and hardness limits for these tap drills?
- These high-speed steel bits have a hardness of 62 to 64 HRC. The titanium nitride coating lets them withstand operating temperatures up to 600 degrees Celsius. You can use them on tough metals, but avoid exceeding these thermal limits to prevent dulling.
