M35 Cobalt steel drill bits can penetrate a 5mm-thick 304 stainless steel plate in 5 seconds. ►While the 5% cobalt makes the bits much more durable,it also makes them more brittle than ordinary HSS bits under improper usage. 【How to use this Drill Bit? Here are some warm tips】 ►Keep the bit vertical and fixation while drilling. ►To avoid drill bit break, 1/16” or smaller bits are suggested used with pin vise. ►Pay attention to the cooling of the bit, adding water or coolant when drilling can increase the life of the bit. 【Warranty: 90 Days】 No worries!

## 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
