Value Collection 210-5083 End Mill Holder NMTB50

Product Description

The VALUE COLLECTION 210-5083 is an end mill holder designed for CNC machining centers and milling machines that use the NMTB50 taper shank standard. It accepts end mills with a 5/8 inch bore and provides a 2.75 inch projection from the spindle face to the tool tip, giving operators clearance for a range of workpiece setups. The nose diameter measures 1.5 inches. With a total runout (TIR) of 0.0004 inch, this holder delivers the concentricity needed for accurate milling operations. Installation and changeover are handled by machinists and CNC setup technicians in job shop and production environments.

This end mill holder is suited for use on vertical and horizontal milling machines equipped with an NMTB50 spindle taper. The 2.75 inch projection makes it appropriate for applications where tool reach beyond a standard holder length is needed. The drawbar thread is sized at 1-8, which is standard for NMTB50 tooling. Through-coolant is not supported by this holder. It is packaged and sold as a single unit.

Key Features

• NMTB50 taper shank for compatibility with standard 50-taper milling spindles
• 5/8 inch bore accepts commonly used end mill shank diameters
• 2.75 inch projection provides reach for varied workpiece geometries
• 0.0004 inch TIR for reliable concentricity during milling operations
• 1-8 drawbar thread size matches standard NMTB50 drawbar hardware
• No through-coolant — suited for dry or flood coolant applications at the workpiece

Compatibility

Designed as an OEM-style replacement or direct-fit tooling holder for milling machines with an NMTB50 taper spindle and a 1-8 drawbar thread.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before inserting or removing the holder. Ensure the taper bore of the spindle and the holder taper are clean and free of chips or debris before seating. Torque the drawbar according to the machine manufacturer's specifications for NMTB50 tooling.
