Kennametal 3641515 Shell Mill Holder CAT40 Taper Shank

Product Description

The KENNAMETAL 3641515 is a CAT40 taper shank shell mill holder designed for milling operations on CNC machining centers. It features a 1.75-inch nose diameter and an overall length of 9.375 inches, with a projection from flange to nose end of 6.0 inches. Through-spindle and DIN flange coolant delivery keeps the cutting zone clear and extends tool life during heavy material removal. Balanced to 12,000 RPM, this holder suits high-speed finishing and production milling applications. It is installed by machinists and CNC setup technicians in job shop and manufacturing environments.

This shell mill holder is suited for use in CAT40-spindle vertical and horizontal machining centers running shell mills, face mills, and similar large-diameter cutters. The 3/4-inch pilot diameter and 3/8-24 lock screw thread provide positive cutter retention. Through-spindle coolant compatibility makes it a practical choice for applications involving steel, cast iron, and other materials that benefit from directed coolant flow at the cutting edge.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Spindle power must be fully locked out and the machine brought to a complete stop before mounting or removing the holder. Use a calibrated torque wrench on the lock screw and follow the machining center manufacturer's drawbar torque specifications. Inspect the taper shank and spindle bore for contamination or damage before seating the holder.
