NordWolf14-Piece M35 Cobalt Drill Bit Set for Stainless Steel, Hard Metals & Cast Iron, Jobber Length with 1/4" Hex Shank, SAE Sizes 1/16" to 3/8" in Storage Case

I purchased this 1/4 hex shank drill bit set because I needed a set that is longer than the average hex shank drill bit sets and I wanted them to be extremely durable. I've experienced countless drill bits to brake off in the stud because they couldn't withstand the heat. This drill bit set shows no signs of weakening. The only drawback of this set is the writing on the drill bits isn't really legible. I like to grab the right size drill bit without guessing but unfortunately sometimes I have to guess when using this set. Other than that it's a great buy!

Great price.

I threw these in to my toolbox for work. I don't drill holes all that often but I can just throw this into my impact and whip out a hole in fairly short order.

Made quick work of my job very useful

I've tried several bits that broke or burned out before even making a dent on a harden steel i was trying to bore.. but this bit chewed through that metal in seconds. Id definitely buy it again

Cuts through steel like butter, but some of the drill bits wobble, because they are mounted in the hex base off-center.

These are the real deal. I bought the 5-piece jobber set, and I've drilled steel, aluminum, composite decking, treated lumber, and wood, and these are the among the best low-cost, quick-change hex bits I've found. Felt like I took a chance when I bought them, but I guessed right.

It look good of course they're new I have not had a chance to use them I hope they perform as good as they look

Worked as expected

My husband seems very satisfied with them!

3 stars:I bought these based on several other reviews and the 1/8 works really good. Cobalt bits + some cutting oil (which keeps the bits cool) = awesome performance.Everything was going great but then when I enlarged the 1/8 hole, and stepped up to the 3/32, the bit broke in half. I've never had anything like this happen before.Didn't put too much pressure on the 3/32 bit either, just let the oil and the bit do its work... YMMV. That's why its a 3 star - would have been 5 stars!But those cobalt drill bits… totally worth it.

after using these cobalt bits i wont waste my time using hss or titanium coated bits for drilling steel again, these cobalt drill bits cut through hardened steel effortlessly and kept their edge after multiple passes when used with a quality cutting fluid
