Collis Tool 63734 Magic Collet Chuck 4MT Taper Shank

Product Description

The COLLIS TOOL 63734 is a Magic Collet chuck with a 4MT (Morse Taper 4) taper shank, designed for use on milling machines, lathes, and machining centers where secure tool holding is required. It provides a 4-7/16 inch projection from the spindle face and accepts collets ranging from 11/16 inch minimum to 1-11/16 inch maximum capacity. Weighing 4.6 pounds, this chuck is built for production environments where consistent tool grip and repeat accuracy are essential. Licensed machinists and tool room technicians are the primary installers of this type of tooling.

This collet chuck suits horizontal and vertical machining setups that use the Magic Collet system with a 4MT taper shank interface. The 4-7/16 inch projection provides clearance for operations on workpieces that require the spindle nose to stand off from the work surface. It does not include through-coolant capability, making it appropriate for dry cutting or flood coolant applications where internal coolant delivery is not needed. Typical applications include milling, drilling, and reaming operations in job shop and production machining environments.

Compatibility

Designed for use with the Magic Collet system on machines equipped with a 4MT (Morse Taper 4) spindle. Compatible with collets within the 11/16 inch to 1-11/16 inch capacity range.

Installation Notes

Installation and removal of taper shank tooling should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. A draw bar or drift may be required depending on the machine spindle design. Inspect the taper shank and spindle bore for burrs, chips, or contamination before seating the chuck, as surface defects will affect tool runout and holding strength. Follow the machine manufacturer guidelines for draw bar torque and taper engagement.
