### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very good quality
  

*by J***R on Reviewed in the United States on March 14, 2023*

These drills do a great job on hardended structural steel and 1/4 plate, dozens of holes on the first bit and still sharp. I use oil and cut a slow speed.

    8MM or 5/16?  Machinist only ones that care.
  

*by D***G on Reviewed in the United States on October 3, 2022*

I was looking for 8mm but got 5/16 (random?)  5/16 is what's on the package and what they measure out at.  I admit that I am being picky here...  .0025" or .04mm off is not enough for most people to ever notice. Plus it's very likely to slightly open or over-drill in the real world enough that it will be just a bit closer to right...  Yeah I'm really being picky now lol.  Bits are clean and sharp and look great.  I'd buy again, maybe next time I'll luck out and get 8mm!
