Bits designed to drill metal have flutes that taper to a point at either a 118- or 135-degree angle. Bits with a 118-degree point are general-purpose bits, while those with a 135-degree point are self-cleaning, which means they shed shards of metal instead of allowing them to accumulate around the shank.Can you sharpen cobalt drill bits?
