## Questions & Answers

**Q: How did this drill bit drill 3/4 "holes on 1/8" thick hard steel?**
A: Well it drills 1/2” holes. I drilled 70 holes in 1/8” steel for a smokeless fire pit and it did not dull at all. I did use some bit lube and it worked great!

**Q: How long is the actual cutting part of the drill bit?**
A: Everything you want to know about the product is in the product description. For me, the cost I have paid is worth it.

**Q: In which country is this product manufactured?**
A: And that is a deal breaker! A hard no way for me!

**Q: What are the advantages and disadvantages of a four spiral groove design compared to a conventional spiral groove design?**
A: The working speed of the 4-slot spiral is very fast because the 4-slot helps to easily remove chips, as the spiral acts like a screw passing through the surface. Straight grooves do not have the same thread effect and require more elbow grease. Finally, it really depends on what you're drilling, but in most cases, the Spiral 4 flute will save some time. But it seems to be faster than any straight flute I have ever used. Impressive!
