High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Gold oxide is a thinner oxide surface treatment than black oxide typically used to identify cobalt steel tools performance is similar to uncoated tools. These round shank tools have flats ground onto three sides to reduce slippage of the bit when used in drill chucks. When run in a counterclockwise direction right-hand cut spiral fluted tools evacuate chips up and out of the cut to reduce clogging. 29 screw machine length drill bits ranging in size from 116 to 12 in 164 increments.
