Value Collection 210-0107 End Mill Holder R8 Taper 1/2 in

Product Description

The VALUE COLLECTION 210-0107 is an R8 taper shank end mill holder designed to secure end mills in milling machine spindles that accept the R8 taper standard. It features a 1/2-inch hole diameter for holding compatible end mill shanks and provides a projection of approximately 54 millimeters from the spindle face to the tool. Weighing 0.94 pounds, this holder is a straightforward toolholding solution used by machinists and tool-and-die professionals working on knee mills and similar machines equipped with R8 spindles. No through-coolant capability is included.

This end mill holder is suited for use in manual vertical milling machines with R8 spindle bores, a configuration common in job shops, maintenance facilities, and machine shops running knee-type mills. It accepts 1/2-inch shank end mills and provides a standard 54-millimeter projection, making it appropriate for general-purpose milling operations where through-coolant delivery is not required. Machinists setting up facing, slotting, or profiling operations on R8-equipped machines will find this a direct-fit toolholding option.
