Excellent Industrial Drill Bit

This industrial-grade drill bit is the real deal. As a result of using this product, I found that it is tough enough to hold up to the most challenging drilling jobs. The cobalt construction makes this bit more durable than others I have used. It cut through the material like butter and kept its edge without any signs of wear. The only downside is the price, but it’s worth it for the high quality. Overall, I highly recommend this bit to anyone in the Industrial and Scientific community looking…

Pros
  • High quality cobalt drill bit for long lasting durability and strength
Cons
  • May dull quickly when used on harder materials such as stainless steel

Great for steel, best in power tool parts and accessories

I had to drill through a 1/8" steel shank, other bits I tried were not sharp enough and heavy. This bit ran at the same speed as the other bits without any problems.

Pros
  • High marks for grip and durability from testers
Cons
  • Not as thick as other cutting tools

Worked great: Power Drill Parts & Accessories

Worked perfectly. For drilling holes for chair glides. Used on 6 chairs, each with four legs. Didn't break. It's a very small drill bit and smooth at the end so you can't flip the drill bit, you just have to drill it forward or the chuck will loosen.

Pros
  • Enjoy
Cons
  • No power
