Not Worth the Investment

This industrial drill bit underperforms when it comes to durability and strength. While it claims to be made with high-speed steel, it could not withstand heavy use in an industrial setting. It is better suited for use in a small workshop for basic projects.

Pros
  • Affordable
Cons
  • Poor Quality

his predecessor bit off more than he could chew.

and this one did an excellent job in the same hole. Obtain. You will like it. And it won't punch a hole in your wallet. Everything else is fair game.

Pros
  • Long Drills
Cons
  • Only available in Black
