Value Collection 210-5433 End Mill Holder CAT40 9/16 in

Product Description

The VALUE COLLECTION 210-5433 is a CAT40 taper shank end mill holder designed for use in CNC machining centers and milling applications. It accepts a 9/16-inch hole diameter and provides a 3-inch projection, positioning the cutting tool at the correct working distance from the spindle face. The nose diameter measures 1-1/2 inches. This holder provides a secure, concentric interface between the machine spindle and the end mill, reducing runout and maintaining cutting accuracy during milling operations. Machinists and CNC operators working in job shops, production facilities, and maintenance environments will find this holder a reliable component for standard tooling setups.

This end mill holder is suited for use in vertical and horizontal CNC machining centers equipped with a CAT40 spindle interface. The 3-inch projection length makes it appropriate for applications requiring moderate tool reach without excessive overhang. It is a common fit for general-purpose milling, profiling, and slotting operations in both ferrous and non-ferrous materials. Through-coolant is not supported by this holder, so external coolant delivery should be used when required.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle interfaces
• 9/16-inch hole diameter accepts standard end mill shanks of that size
• 3-inch projection (76.20 mm) positions the cutting tool at a practical working distance
• 1-1/2-inch nose diameter for secure tool clamping
• No through-coolant - use with external coolant delivery systems
• Weighs 3 pounds for a solid, balanced tooling assembly

Compatibility

Designed as an OEM-style replacement or standard tooling addition for CNC machining centers equipped with a CAT40 taper spindle interface accepting 9/16-inch shank end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before inserting or removing toolholders. Use the appropriate torque wrench and pull stud specification for your machine's CAT40 drawbar system - consult your machine tool manual for the correct pull stud and retention knob type before installing this holder. Inspect the taper bore and spindle taper for chips, burrs, or contamination before seating the holder to ensure full contact and minimize runout.
