Techniks 22941B End Mill Holder CAT50 3/4 in Bore Through Coolant

Product Description

The TECHNIKS 22941B is a CAT50 taper shank end mill holder designed for secure tool retention in CNC machining centers. It accepts a 3/4 inch bore and delivers a 4 inch projection from the spindle face, making it suited for operations that require extended reach. The nose diameter measures 1-3/4 inches, and the overall length is 8 inches. Built-in through coolant capability directs cutting fluid directly to the tool tip, improving chip evacuation and extending tool life in demanding milling applications. This holder is installed by CNC machinists and toolroom technicians working with CAT50 spindle-equipped machines.

This end mill holder is used in production and job-shop environments where CAT50 tooling is standard. The 4 inch projection suits applications requiring clearance around fixtures or workpiece features. Through coolant support makes it appropriate for high-speed milling, deep-pocket operations, and materials that generate significant heat during cutting. It is compatible with any CAT50 spindle that accepts standard end mill holders with a 3/4 inch bore.

Key Features

• CAT50 taper shank for positive spindle engagement in CAT50 machining centers
• 3/4 inch bore accommodates standard end mill shanks of that diameter
• 4 inch projection provides extended reach for fixture-clearance and deep-feature work
• 1-3/4 inch nose diameter for rigid tool support close to the cutting zone
• Through coolant design channels fluid directly to the cutting edge
• 8 inch overall length suits a range of vertical and horizontal machining setups

Compatibility

Designed for use with CAT50 spindle machining centers that accept standard end mill holders with a 3/4 inch bore and through coolant capability.

Installation Notes

Installation and removal should be performed with the machine spindle fully powered down and locked out per applicable lockout/tagout procedures. Use a proper CAT50 pull stud and the correct torque wrench rated for the toolholder size when securing the retention knob. Inspect the taper shank and spindle bore for nicks or debris before seating the holder. Through coolant connections should be verified for alignment and seal integrity before running coolant under pressure.
