These jobbers'-length bits have the rigidity and length required for most applications.
Because softer metal, like aluminum, brass, and bronze, can clog a bit, the flutes on these bits lift chips out of the hole. Also known as slow-spiral drill bits.
Designed to lift chips out of the hole, these bits reduce clogging and improve coolant flow.
Also known as gun taps, the taps in these sets have spiral-point flutes that push chips ahead of the tap and out of through holes.
