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!!
