The DORIAN TOOL 73310145307 is a keyless drill chuck designed for CNC machining centers and milling applications that use CAT40 tooling systems. It accepts drill bits and round-shank tooling up to 1/2 inch capacity and mounts via an integral shank with a taper-style connection to the spindle. The 2-inch sleeve diameter provides a secure grip surface for tool changes. At 4.2 pounds, the chuck is built for the rigors of production environments. Installation requires no key for bit changes, reducing tool-change time at the spindle. This chuck is suited for machinists and tool-room technicians working with CAT40 equipped machine tools.
This chuck is intended for use in CAT40 spindle tooling setups on vertical machining centers and milling machines. It is a direct-mount, integral shank unit, meaning no separate arbor is required between the chuck body and the machine spindle. Typical applications include drilling, light boring, and similar operations where a keyless chuck is preferred over a collet or keyed chuck for faster bit changes during production runs or tool-room work.
Designed for use with CAT40 spindle tooling systems on vertical machining centers and milling machines equipped with CAT40 integral shank toolholders.
Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before installing or removing any toolholder. Inspect the CAT40 taper and spindle bore for debris or damage before seating the chuck. Follow the machine manufacturer's drawbar torque specifications - do not use generic torque values not supplied by the machine OEM.
