  • Buy these!
Style: 13pcs Cobalt Drill
Nice set. Would be 5 star rating except I wish they had the flat side on the shank to differentiate them from my other bits. With proper lubricant, speed and pressure the bit I used went through stainless steel no problem. Would buy again. GREAT PRICE TOO!

Style: 13pcs Cobalt Drill
Very sturdy bits. Used them to drill through brass, went through no problems. Pleased with my purchase

  • Good drills, pretty crappy case.
Style: 115pcs Cobalt Drill
These are pretty good drills with minimal runout. They have worked well and cleanly in wood and steel so far. The case, however, is very cheap, thin, and bent already on delivery. I had to do some repair to make it usable. Still, the drills are pretty good quality for such a great price.

  • That they work.
Style: 13pcs Cobalt-Left Hand
Did a great job getting out a broken bolt.

  • Drill bits
Style: 60pcs Number Size Cobalt Drill
Reasonable price for bits I only need occasionally.

  • Could not drill through stainless steel
Style: 13pcs Cobalt Drill
I tried using the drill bits to go through stainless steel, did not do the job. I wasn’t having any success with my other drill bits either, so maybe the material I was working is just really hard.

  • Sharp and true (no wabble)
Style: M35-5/8"(4PCS)
Great drill bits. They cut very well. (Be sure to use them with a slow speed to prevent over heating which leads to dulling). They are truly straight, no tip wabble.
