Techniks 22967 CAT40 End Mill Holder 2.5 Inch Projection

Product Description

The TECHNIKS 22967 is a CAT40 taper shank end mill holder designed for securing end mills in CNC machining centers. It features a 2.5-inch projection and an overall length of 5.187 inches, making it suited for standard reach milling applications. The bore diameter is 10 mm, and the nose diameter is 35 mm. This holder is installed by machinists and tooling technicians on CNC vertical or horizontal machining centers equipped with a CAT40 spindle interface. Solid construction and precise taper geometry help maintain tool concentricity and repeatable positioning at the spindle.

This end mill holder is intended for use in production and job-shop CNC environments where a CAT40 toolholder standard is required. It is well suited for applications involving standard-shank end mills with a 10 mm bore. The 2.5-inch projection provides clearance for typical face milling, slotting, and peripheral milling operations without extending excessively into vibration-prone territory. No through-coolant feature is present, so external coolant delivery or flood cooling is the appropriate method for chip evacuation and heat management.

Key Features

• CAT40 taper shank for compatibility with CAT40 spindle interfaces on CNC machining centers
• 10 mm bore diameter accommodates standard 10 mm shank end mills
• 2.5-inch projection for adequate reach in common milling setups
• 35 mm nose diameter provides a robust clamping body
• Overall length of 5.187 inches for predictable tool assembly and offset programming
• No through-coolant - external or flood coolant required

Compatibility

Designed as an OEM-style replacement or direct-fit toolholder for CNC machining centers with a CAT40 spindle taper interface accepting 10 mm bore end mill holders.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machining center spindle before inserting or removing any toolholder. Use the appropriate pull stud and a calibrated torque wrench on the retention knob per the machine tool manufacturer specifications - do not hand-tighten retention hardware. Verify tool runout with a dial indicator after assembly to confirm concentricity before beginning a cut.
