Techniks 22965 End Mill Holder CAT40 2.5 Inch Projection

Product Description

The TECHNIKS 22965 is a CAT40 taper shank end mill holder designed for use in CNC machining centers requiring secure, concentric tool holding. The holder features a 2.5-inch projection and an overall length of 5.187 inches, positioning the cutting tool at a consistent gauge distance from the spindle face. The bore diameter is 8 mm, suited for end mills and tooling shanks of that diameter. The 28 mm nose diameter provides a robust clamping area. This holder is installed by machinists, toolroom technicians, and CNC setup personnel working on vertical or horizontal machining centers equipped with CAT40 spindle interfaces.

This end mill holder is appropriate for production and job-shop environments running CNC machining centers with CAT40 spindle tapers. The 2.5-inch projection is well-suited for applications where moderate tool reach is required, such as face milling, slotting, and peripheral milling operations in steel, aluminum, and other machinable materials. It does not include through-spindle coolant capability, so external coolant delivery should be used where chip evacuation or heat management is a concern.

Key Features

• CAT40 taper shank for direct mounting in standard CAT40 spindle interfaces
• 2.5-inch projection for consistent gauge length and moderate tool reach
• 8 mm bore diameter accommodates end mills and tooling shanks of that size
• 28 mm nose diameter provides a solid clamping surface
• Overall length of 5.187 inches for predictable tool length management
• No through-coolant port - compatible with external coolant delivery setups

Compatibility

Designed as an OEM-style toolholder for CNC machining centers equipped with a CAT40 spindle taper interface.

Installation Notes

Installation and tool changes should be performed with the machine in an E-stop or powered-down state and the spindle fully stopped. Use a CAT40-compatible tool setter or pull stud when mounting in the spindle. Tighten the end mill set screw to the toolholder manufacturer's recommended procedure using the appropriate hex key. Verify tool runout with a dial test indicator before commencing cutting operations.
