Review on Bosch BL9IM Black Impact Piece by Justin Hollins

I got this to drill metal. The 1/8 inch bit is broken. Broke again after sharpening. I know what you're thinking, probably user error (high speed, too much pressure, etc.), right? Well I can't rule it out, although I was careful. But other 1/8's from other manufacturers (some sharpened, some not) still work fine with my "drilling style". However, larger sizes seem to be acceptable.
