Collis Tool 75022 CAT40 End Mill Holder Through Coolant

Product Description

The COLLIS TOOL 75022 is a CAT40 taper shank end mill holder designed for CNC machining centers requiring secure tool retention and integrated coolant delivery. Built with a taper shank interface, the holder provides rigid, repeatable tool holding suitable for high-speed milling operations. It features a 3-inch projection, a 1-3/4 inch nose diameter, and a 2.25 inch flange diameter. Through-spindle and DIN flange coolant compatibility supports both flood and directed coolant strategies, making this holder a practical choice for shops running production milling with coolant-intensive toolpaths. Machinists and toolroom technicians install this holder as part of a standard CAT40 tooling assembly.

The 75022 is suited for use on CNC vertical and horizontal machining centers equipped with a CAT40 spindle taper. The 3-inch projection accommodates applications where clearance from the spindle face is needed, such as deep-pocket milling or setups with workholding interference. The 20 mm bore diameter accepts standard 20 mm shank end mills. Through-coolant capability supports consistent chip evacuation and tool life in ferrous and non-ferrous cutting applications.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 machining center spindles
• 3-inch projection for extended reach in deep-pocket and obstructed setups
• 20 mm bore diameter accommodates standard 20 mm shank cutting tools
• Through-spindle and DIN flange coolant delivery for directed coolant at the cutting zone
• 1-3/4 inch nose diameter and 2.25 inch flange diameter for stable tool clamping geometry

Compatibility

Designed for use with CAT40 spindle taper machining centers accepting standard end mill holders with through-coolant capability.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machining center spindle before mounting or removing the holder. Use a calibrated torque wrench and the appropriate CAT40 retention knob when securing the holder in the spindle. Verify coolant port alignment and check for runout with a dial indicator before beginning a cutting operation.
