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
21 screw machine length drill bits ranging in size from 1/16" to 1/4" in 1/64" increments and from 9/32" to 1/2" in 1/32" increments
