great bits

I busted 2 of the bolts holding a twin engine in a mower I was working on and I drilled both bolts out with just one bit and it's ready for more work. Best set I've ever owned.

Cobalt bits on metal are best!

I drilled progressive holes in my front bucket to add on teeth to the bucket. Starting with 1/4" and ending with 1/2' dur to the thickness of the metal. The cobalt bits did a great job to fininfh the final hole.
