Techniks 22915-2.5 End Mill Holder CAT40 3/8 Inch Hole

Product Description

The TECHNIKS 22915-2.5 is a CAT40 taper shank end mill holder designed for use in CNC machining centers. It accepts a 3/8 inch bore and provides a 2.5 inch projection from the spindle face, with a 1 inch nose diameter and an overall length of 5.187 inches. This holder secures end mills and similar cutting tools in CAT40-compatible spindles, delivering rigid tool clamping for milling operations. It does not include through-coolant capability. Machinists and CNC setup technicians are the primary installers of this toolholder.

This end mill holder is suited for use in vertical and horizontal machining centers equipped with CAT40 spindle interfaces. The 2.5 inch projection makes it appropriate for applications requiring moderate tool extension, such as face milling, slotting, and peripheral milling on workpieces where clearance is a factor. The 1 inch nose diameter provides a stable clamping surface for standard end mill shanks sized at 3/8 inch.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in an appropriate safe state before changing toolholders. The taper and spindle bore should be clean and free of chips or oil before seating the holder. Follow the machine tool manufacturer torque guidelines for the retention knob, as specified in the equipment documentation.
