Perfect for the job
Is exactly as expected, worked great did the job 12 other bits couldn't!! I have a shop so I get many tools. These held up to the hype. Cut through engine block exhaust bolt. Bolt broken in block.

Made holes where I wanted them
I drilled over 50 holes into a 1" steel tube. I used a drill press and lubricated the bit with cutting oil before each hole. Bit worked great. No slipping on the rounded surface. Cut the steel with little pressure. Easy to hit my mark.

First bit broke immediately.
7/32nds bit broke on me the first time I used it. The step portion cracked off right away then the rest of the bit spun around with no bite. Had to fish out the chips with pliers then used a Bosch cobalt bit to finish the job. Will update the score up if the other bits hold up better

Be patient.
These bit are by far the best I've used FOR HARDENED STEEL. I've purchased multiple $200 drill sets. The picture supplied was of my auger head for splitting logs into quarter logs. When the head got stuck it sheared 6 grade 8 hardened steel bolt flush to the head. Anyone drilling this metal knows the hours of frustration involved. Drill America bits buried themselves in effortlessly.....And that is the key. These are crazy hardened bits. " which means for all u haters " If u apply too much pressure...if your drill slips...if your drill speed is too fast...if you bite of more than the bit can handle, U ARE GONNA SNAP THE BIT. I would not suggest these bit for hand drilling thick soft metal. they are just too aggressive. if u have a drill press u might be fine. have the right tool for the job and don't leave bad reviews for operator error. These bits are the 💩

Works great for drilling through hardened steel, where others fail!
Exactly what I needed. Broke several other titanium bits before buying these. I used them to drill into Jeep Hardened Steel Roll Cage for Hi-Lift Mount. And these did the trick. Just go slow and use drilling oil, and you’re good to go. Also used these to drill through four other steel plates up to 1/2” thick. And cut like butter. Highly recommend.
