## Questions & Answers

**Q: would these bits drill a hole in stainless steel?**
A: They can. I made sure that I kept them well lubricated but still had to sharpen after about 8 holes.

**Q: What does Nitride Coating actually mean?**
A: Nitriding is a heat treating process that improves heat-resistance, toughness and durability.

**Q: So why does the picture show left hand drill bits when i assume that these are right hand?**
A: As far as I know they are right hand drill bits. Stated another way when inserted into a drill which is set for forward they will dig into the piece you are drilling. I don't recommend for cutting metal - while usable they wore out quickly assembling some metal ducting for a dust collector.

**Q: I received my order and the bits are silver the add color is gold normal for metal bits , did I get the wrong thing.**
A: I recive mys and mysare normal

### ⭐⭐⭐⭐⭐ FIFTH COMPNY WAS THE CHARM , HAPPILY GOT ER DONE
*by D***R on August 20, 2025*

I tried 5 different Cobalt bits. Ordered from 3 different companies. They weren't sharp. Sent them back. Took a chance and ordered from a 4th company with good reviews for sharpness. A gain the bits were not sharp. Dent them back. Thought I would give it one more fifth try from this company. HURRAH !! Opened the package , took a bit out and tried it. IT DRILLED THE HOLE IN MILD STEEL ALMOST LIKE BUTTER. THEN DRILLED 2 MORE HOLES WITH THE SAME BIT. NO PROBLEMS DRILLED THEM EASILY. WOULD DEFINATELY RECOMEND THESE BITS. ARRIVED IN ONE DAY. VERY SATISFIED.
