Query: At 1/8 inch, these are really terrible.

I've used quite a few bullet-point bits successfully, but in the 1/8" size these are completely terrible for use in steel. The bullet point really grabs, so the second it pops-through back-side while drilling steel, the bit breaks. I literally broke four bits in four holes. I was so irritated that I took them back to the store for a refund just to complain.They break right where the flutes turn in to the full shank. The flutes of the drill are not full-diameter, they've been reduced possibly to decrease friction or something, with only a little ridge full diameter. But that reduction in area, in combination with a sharp tip breaking through, snaps bits. I put an old dull bit in and drilled the rest of the barn-metal I was piercing for the rest of the day with only one bit.I'm also irritated that B&D; only makes bits in China now. I'm sure that influences my opinion of why they break. Chinese tools have always been junk. Bring these jobs home.
