    • Serious bits. WINNER vs 5 other brands.
Style: M35-5/16-10pcs
I’m repairing and upgrading a utility trailer, I was going to have to drill 40+ holes through single/double layered 1/4” steel. I decided to buy several different brands of drill bits for comparison. I started with my favorite brand Dewalt, then ACE, Bosch, Irwin, Stinger, and finally GMTools. ACE failed, I drilled through 1.5” of wood, reached 1/4” steel and it broke. One of my DeWalt’s same result. B/I/S bits took 3-6 minutes to penetrate with oil and pilot holes. Frustrated, I ordered the these GM bits. Killers, eat steel! 3x faster than any other bits. You need holes these WILL make holes for you. ... show more

    • Great bits.
Style: M35-1/4-10pcs
These drill bits are great. They work as you'd expect. So far they have gone through wood and steel with no problems and have remained sharp. Would I purchase them again? Yes Would I recommend them to a friend? Yes

    • Way better than DeWalt bits.
Style: 13 pcs Cobalt
I had a new set of DeWalt bits and it took me 30 minutes to drillone hole through the pinch seam on my vehicle. The bits were trash after that. I ordered these cobalt bits, and drilled 5 more holes in 10 minutes. After drilling 5 holes through very hard metal, the bits were worn out. I was amazed at how well thesse worked. I ordered a new set for the next project. ... show more
