Customers find these drill bits excellent in quality and performance, particularly noting their effectiveness in drilling through hardened steel and mild steel. Moreover, the cut quality receives positive feedback, with one customer mentioning they’re strong enough to drill through leaf spring metal. However, durability is a concern, with multiple customers reporting that the bits break easily. Additionally, opinions on value are mixed, with some finding them well worth the price while others consider them overpriced.

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.
Jeffrey A. Flach –
These are trash
So I have had about 10-11 months to use these and I can honestly say they are total trash. The bits are brittle and break almost every time I use them. I thought it was a fluke at first but they donât even drill as good as cheap cheap store bits. So if you want to start a hole and then plug it with the tip of a drill bit when it brakes then these are for you.

Lucas S. –
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.

Bits drill nicely
Bigger bits work great , small ones break easily but it could also be me

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.
