Using one of these (1/2") bits today, in an impact driver. Drilling through a layer of steel, wood, steel, and then a 2x4 stud. Marrying some brackets to a framed pony wall in a Master Bedroom. The bit bound, the shank snapped where it narrows and seats in the holder. Needless to say, a bit of torque going on suddenly. No damage to me, other than a little sore (muscles) in my arm/hand. The worst part of it is... now I have to try and coax the remainder of the shank from my impact driver, and find a replacement bit (which I borrowed).
Checked the bit's usefulness by chucking it into my drill... no love, the rest of the shank bent, and it's displaying the wobble of death pretty bad.
