Techniks 22993 End Mill Holder CAT50 4 Inch Projection

Product Description

The TECHNIKS 22993 is a CAT50 taper shank end mill holder designed for use in CNC machining centers that accept the CAT50 spindle interface. With an overall length of 8 inches and a 4-inch projection, this holder positions the cutting tool at a fixed gauge-to-tip distance suited for deep-reach milling operations. The bore diameter is 25.00 mm and the nose diameter is 65.00 mm. Weighing 8.4 pounds, the holder is built for rigid, high-torque applications. Licensed machinists and CNC setup technicians install this toolholder as part of a modular tooling assembly on vertical and horizontal machining centers.

This end mill holder is used in production and job-shop machining environments where CAT50 spindle tooling is standard. The 4-inch projection makes it applicable for milling operations requiring additional clearance between the spindle nose and the workpiece or fixture. It is well-suited for face milling, slot milling, and peripheral milling tasks on medium to large CNC machining centers running at production feeds and speeds. No through-coolant capability is present, so external coolant delivery must be used when flood or mist cooling is required.

Key Features

• CAT50 taper shank interface for compatibility with standard CAT50 spindles
• 4-inch projection for extended reach in deep-cavity or fixturing-clearance applications
• 25.00 mm bore diameter for secure end mill clamping
• 65.00 mm nose diameter provides a robust, vibration-resistant grip
• 8-inch overall length suits a range of vertical and horizontal machining center setups
• No through-coolant port - external coolant supply required

Compatibility

Designed as an OEM-style replacement and standard toolholder for CNC machining centers equipped with a CAT50 spindle taper interface.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machining center spindle before inserting or removing any toolholder. Use the appropriate retention knob torque specifications provided by the machine tool manufacturer, and inspect the taper bore and spindle seat for nicks or contamination before seating the holder. Do not exceed the spindle speed or torque limits posted on the machine nameplate.
