These are awesome!
Watched my mechanic use these. I was so IMPRESSED I bought a set. This is straight up the real deal. I watched him center punch some 1/4 steel plate. Used the 1/4 bit and drilled through it in under 3 seconds. 4 holes, 3 seconds each hole. Then put in the 3/8 bit. Went through each hole enlarging in under 2 seconds!!! Then enlarged with 1/2 bit. Went through in under 3 seconds! Are you kidding me...1/4 plate steel. This is for real. He was using a snap-on 1/2 air drill, and I admit that is one wicked, nasty, high torque drill...he said a normal drill would stall...but these bits are nasty. I'll send a video soon.

Too delicate to drill anything but soft material
The tips break off very very easily. Not for use for metal. Cheap!!

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 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.

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.

Drill bits
Great idea for a drill bits but they break fairly easily. Great for steel and mild stainless but clogs quickly with aluminum.
