Heavy Duty Carbide Drill

Perfect for our work. I bought them because everything I bought elsewhere broke all at once. I've only used ONE drill bit since I've had them. Plenty for a tool box to save on when the ONE bit breaks.

Pros
  • Power Tool Parts & Accessories
Cons
  • Slightly Torn

EXCELLENT What more can I say.

Very high quality precision drill. They have the right angle at the top and a sharpness for excellent drilling. I like these bits with three flat, non-slip grips. Like I said. What else can I say or what you ask. Thank you for letting me share my thoughts and opinions on these exercises and I hope it helps you make a decision one way or another. CN

Pros
  • twist drill
Cons
  • There are other interesting options.

BAD, split point was not sharpened properly, see picture, wanders and breaks.

In my drawing, the left hand silver bit shows a properly centered split point. The faulty ones I received are on the right. Everything I have is useless to me. I use them on my CNC lathe and they don't drill very deep so they break. UPDATE: I checked all split points under 10x magnification. All bits have cracks in different places, there is definitely a problem in both production and quality control.

Pros
  • Electric Drill Parts and Accessories
Cons
  • Fragile
