Kennametal 1013353 End Mill Holder CAT40 7/16 Inch

Product Description

The KENNAMETAL 1013353 is a CAT40 taper shank end mill holder designed for precision milling operations on CNC machining centers. The holder accepts a 7/16-inch tool shank and features an integrated through-coolant design that delivers cutting fluid directly to the tool tip for improved chip evacuation and tool life. With a 4.5-inch projection and a 1-1/4-inch nose diameter, this holder is suited for applications requiring extended reach. It is balanced to 12,000 RPM, making it appropriate for moderate- to high-speed spindle work. Machinists and CNC setup technicians are the primary installers of this toolholder.

This end mill holder is used in vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. The through-coolant capability makes it well suited for operations involving ferrous and non-ferrous materials where heat management and chip control are critical. The 5/8-11 drawbar thread is standard for CAT40 tooling systems. It is commonly installed in job shops, production machining environments, and tool rooms requiring reliable, repeatable tool holding at moderate spindle speeds.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle interfaces
• 7/16-inch hole diameter for direct shank tool holding
• Through-spindle coolant delivery channels cutting fluid to the tool tip
• Balanced to 12,000 RPM for stable high-speed operation
• 4.5-inch projection provides extended reach for deep-cavity or complex-fixture setups
• 5/8-11 drawbar thread matches standard CAT40 machine tool specifications

Compatibility

Designed as an OEM-style replacement and standard toolholder for CNC machining centers with CAT40 taper spindle interfaces and through-spindle coolant capability.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Always power down and lock out the machine spindle before inserting or removing toolholders. Use a properly calibrated torque wrench and manufacturer-recommended drawbar torque procedure when securing the holder in the spindle. Inspect the taper shank and spindle bore for contamination or damage before seating the holder to ensure accurate tool positioning.
