HSS Cobalt Drill Bit Set 3/32 Inch 10Pcs M35 Co Twist Jobber Length Steel Metal Drill Bits

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..

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.

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.

Good bits. They cut through steel pretty well.BUT FYI, these WILL NOT touch hardened spring steel at all. Just a friendly tip.

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

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.

Great Product

I am building a metal building and the need to drill many holes to mount the windows to the metal frame has tested me and the drill bits. Three drill bits lasted the entire day while mounting windows.
