Hot Q&A
Q: How to extend the service life of the drill?
A: Use cutting fluid to reduce heat, avoid excessive RPM, ensure good chip clearance during drilling.
Q: Can this drill work on stainless steel or hardened steel?
A: Yes. Choose carbide-tipped or cobalt drills with matching coatings to prevent premature dulling.
Q: What’s the difference from standard drills?
A: Our diameter drill achieves single-pass high accuracy, saves time, and improves hole finish quality.
