Kennametal 3641513 Shell Mill Holder CAT40 Taper Shank

Product Description

The KENNAMETAL 3641513 is a CAT40 taper shank shell mill holder designed for use on CNC machining centers equipped with CAT40 spindle interfaces. It features a 1.75-inch nose diameter and an overall length of 6.875 inches, with a projection from flange to nose end of 3.5 inches. The holder supports through-spindle and DIN flange coolant delivery, enabling direct coolant flow to the cutting zone. A 3/8-24 lock screw thread secures the shell mill to the arbor. Balanced to 12,000 RPM, this holder suits high-speed face milling and surface milling operations. It is installed and serviced by CNC machinists and toolroom technicians.

This shell mill holder fits standard CAT40 machining centers used in production and toolroom environments. It is suited for mounting shell mill cutters with a 1.75-inch bore in applications such as face milling, shoulder milling, and surface finishing on ferrous and non-ferrous materials. The 3/4-inch pilot diameter provides positive cutter registration. Through-spindle coolant capability makes it appropriate for operations where chip evacuation and tool life are priorities in moderate to high-volume cutting environments.

Key Features

• CAT40 taper shank interface for compatibility with standard CAT40 machining center spindles
• 1.75-inch nose diameter for mounting shell mill cutters with matching bore size
• Through-spindle and DIN flange coolant delivery for direct coolant flow to the cutting edge
• Balanced to 12,000 RPM for stable performance in high-speed milling applications
• 3/8-24 lock screw thread for secure cutter retention
• Overall length of 6.875 inches with 3.5-inch flange-to-nose projection for reach and rigidity

Compatibility

Designed as an OEM-style shell mill holder for CNC machining centers with a CAT40 spindle interface accepting shell mill cutters with a 1.75-inch bore and 3/4-inch pilot diameter.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machining center spindle before mounting or removing the holder. Use the correct pull stud and torque the lock screw to the machine tool manufacturer's specification using a calibrated torque wrench. Verify runout with a dial indicator after installation before commencing any cutting operation.
