Disappointing Quality Drill Bit

After I put it to the test in my industrial and scientific workshop, it failed to live up to its claims of durability and strength..

Pros
  • None
Cons
  • Poor quality, easily dulls.

Revainrating 5 out of 5

much better than HSS for harder steels and exotic alloys.

Turned to Kobalt after destroying all of his High Speed Steel (HSS) drills. SS is still extremely difficult to cut because it hardens. I've found that I always get good cuts when using cobalt drills with coolant at lower RPMs. I haven't found any reason why I can't use this for other cutting jobs (something like concrete or tungsten) so I'll take care of that first for now.

Pros
  • Twist Drill
Cons
