Affordable & performance
With some cutting oil i only needed 1/5 of the drill bits to make it through about 1/2" of titanium. I was very happy with both price and performance of these bits.

Good product for doing large jobs where numerous holes are drilled, cutting oil is required.
Good product for doing large jobs where numerous pilot holes need to be drilled, cutting oil is required to extend the life of the drill bits..

Okay, but not the best on Amazon
These seem like okay bits for the price, but they had a tough time drilling through a piece 1/16" stainless steel. The similar bits from OEM Tools Direct on the Amazon site cost a couple bucks more for 10, but went through steel with less time, effort and ruined bits. I'd recommend their set first.

Great performing drills.
I was initially worried about whether or not these drills would perform the task at hand - drilling a dozen holes through a steel I-beam. A real steel I-beam. I am pleased to report that 4 of the drills are unused. It took only one bit to do the job and it's still in great shape.

High quality
Sharp and high quality. Tougher than the cobalt bits I had before these. They hold an edge for a long time, even in hardened steel.

Good bits
I used these bits to drill through stainless steel on trailers. They cut pretty good.
