A taper shank drill bit is a heavy-duty drill bit designed with a tapered shank (instead of straight or hex) that fits directly into a machine spindle or a matching tapered sleeve.
Tapered Shank (Morse Taper)
The shank gradually narrows toward the end.
Fits directly into the Morse taper socket of drilling machines, lathes, or milling machines.
Self-holding design: friction locks the drill in place during operation.
Often has a tang at the end to help eject the bit from the socket.
