Very functional with no drifting like your typical bit do

This does not suck the bit into the material as other bits do. Also, if you drill into a metal plate, this has minimal burs on the other side.

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 š©

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.

Use lube to keep from dulling the bits

Love these bits, would've bought the larger set but really expensive. This sampler set contains the bits I use the most so this will do for now. Cheap bits for other sizes.

Awesome design incorporating the step bit into each one of these. Only downside is the markings on the container is difficult to read, but my 53 year old eyes aināt what they used to be either.
