You get what you pay for!!
Very clean, fast drilling in everything I have tried so far from wood to stainless steel. Expensive but extremely high quality and compact, convenient storage case. As a professional truck mechanic l highly recommend.

Good for metal
These bits are good for going thru metal, maybe to good. They get such a good “bite” that I have snapped one bit already.

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

Drill bit works very good drill through metal fast

Good drills, but arrived with cracked plastic cover.
So far, the drills look awesome. The only reason I didn’t leave a 5 star review is that the plastic canister arrived with a cracked cover…hoping that Drill America sends a new one so I can give it a full 5-star review.
Michael Buckley –
Bits drill nicely
Bigger bits work great , small ones break easily but it could also be me
Adam Lee Kemp –
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 youâre good to go. Also used these to drill through four other steel plates up to 1/2â thick. And cut like butter. Highly recommend.

Unique & well worth the money.
Best drill bits in the world !! Have used them where standard bits wouldnât make a dent !! Not necessary to prick punch when drilling hard metal.
