Kennametal 1013375 End Mill Holder CAT40 1/2 Inch

Product Description

The KENNAMETAL 1013375 is a CAT40 taper shank end mill holder designed for milling operations on CNC machining centers. It accepts a 1/2 inch bore and features through-coolant capability, delivering coolant directly through the spindle to the cutting zone. The holder provides 6.62 inches of projection from the spindle face, a 1-1/4 inch nose diameter, and a clamping depth of 8.13 inches. It is balanced to 12,000 RPM, making it suitable for general-purpose milling work where thermal management and tool life are priorities. The drawbar thread is 5/8-11. Licensed machinists and CNC setup technicians are the primary installers.

This end mill holder is suited for use in vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. The 6.62 inch projection makes it appropriate for applications requiring extended reach, such as deep-pocket milling or workpiece clearance situations. The through-spindle coolant path supports high-speed cutting of ferrous and non-ferrous materials where directed coolant flow reduces heat buildup and chip evacuation problems. Packaging quantity is 1 unit per order.

Key Features

• CAT40 taper shank for standard machining center spindle interface
• 1/2 inch bore diameter for compatible end mill shanks
• Through-coolant design with through-spindle coolant type for directed cutting fluid delivery
• Balanced to 12,000 RPM for stable high-speed operation
• 6.62 inch projection for extended-reach milling applications
• 5/8-11 drawbar thread size for secure spindle retention

Compatibility

Designed for use in CNC machining centers with a CAT40 taper spindle interface and a 5/8-11 drawbar thread. Through-coolant use requires a through-spindle coolant-capable machine.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician following the machine tool manufacturer's tooling procedures. Power down and lock out the machining center before installing or removing the holder from the spindle. Torque the drawbar to the machine manufacturer's specification using appropriate spanner or torque wrench tooling. Verify runout after installation with a dial indicator before beginning a cutting operation.
