Value Collection 210-5721 End Mill Holder CAT50 3/16 in

Product Description

The VALUE COLLECTION 210-5721 is a CAT50 taper shank end mill holder designed for use in CNC machining centers and milling operations. It accepts end mills with a 3/16 inch hole diameter and provides a 4 inch projection from the spindle face, giving the cutter the reach needed for deeper workpiece access. The nose diameter measures 25/32 inches. At 8 pounds, this is a solid, rigid toolholder built for standard milling applications. Installation is performed by qualified machinists or tool crib technicians working with CAT50-compatible spindles.

This end mill holder fits CAT50 taper spindle machines, which are common in mid-to-large-capacity vertical and horizontal machining centers found in production and job shop environments. The 4 inch projection makes it suitable for applications requiring extended reach without sacrificing radial rigidity. The 3/16 inch bore accommodates small-diameter end mills used in finishing, slotting, and light profiling work. No through-coolant is provided, so flood or mist coolant delivery must be handled externally.

Key Features

• CAT50 taper shank for compatibility with standard CAT50 spindle interfaces
• 3/16 inch hole diameter for small-diameter end mill clamping
• 4 inch projection (101.60 mm) for extended reach applications
• 25/32 inch nose diameter for clearance in close-tolerance setups
• No through-coolant — external coolant delivery required
• Solid construction at 8 pounds for rigid tool holding

Compatibility

Designed for use with CAT50 taper spindle machining centers. Accepts end mills and cutting tools with a 3/16 inch shank diameter.

Installation Notes

Installation is performed by a machinist or tooling technician. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before mounting or removing the holder. Use a CAT50-rated retention knob and a torque wrench sized for the drawbar specification of the machine — do not use impact tools on the retention knob. Verify tool runout with a dial indicator after seating to confirm proper clamping before machining.
