Keyless Drill Chuck

A drill chuck is needed in order to use a spiral drill with cylindrical shank in a machine tool. Quick-action drill chucks make it possible to change tools with little loss of time and power. The chuck can be opened and closed by hand even at relatively high clamping pressures. A wide selection of tool holder bits and drill chuck mounts in the Knuth Machine Tools accessory program allows these drill chucks to be used in many types of machines.
