## Questions & Answers

**Q: Do they have mm measurements on them too ?**
A: Not as I can remember, but it's easy calculate. 3/16" would be 25.4 devided by 16 multiply by 3 = 4.76mm
25.4 being an inch in millimetres.
Apologies if this is obvious to you

**Q: Will these bits go through 6mm iron?**
A: Yes if used at slow RPM and use cooling fluid. I have used them in 12mm steel beams with no problems as long as they are kept cool and lubricated. High speed and dry and they will burn out fast (like all drills will)

**Q: Description states cobalt, details state 'true m2'. cant be both, 5% cobalt is m35 or 8% is m42. m2 is basic tungsten–molybdenum? please confirm.**
A: M2 is a molybdenum series high-speed steel that has the advantages of high toughness, the material of those step drill bits is M2 high-speed steel, The surface of the step drill bits is Cobalt coating, for smoother cooler cutting.

**Q: Would these drill out my wheel nut on my car**
A: No! Definitely no!
These are designed to use as low speed “hole” cutters. They should be used ONLY at low speed and preferably with a cutting lubricant. 
To drill out the wheel nut on a car would need a really good conventional drill with a high cutting speed.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent Quality!
  

*by H***. on Reviewed in the United Kingdom on 19 January 2018*

Ordered these, and given the price, did not expect it to be anything other than mediocre quality. Oh boy was I wrong! Great quality and the aluminium case is a big bonus!!As usual, Amazon delivered quickly and when I opened the case was amazed to find just how good the quality is. My son, an aerospace engineer, had a look and promptly ordered a set for himself to use at home he was so impressed by the quality. "Excellent for home DIY" was what he said.
