Value Collection 210-0308 R8 End Mill Holder Set 8 Pc

Product Description

The VALUE COLLECTION 210-0308 is an 8-piece R8 taper end mill holder set designed for use in Bridgeport-style vertical milling machines and other equipment with R8 spindle tapers. The set covers a range of hole diameters from 3/16 inches to 1-1/4 inches, giving machinists and tool-and-die workers a matched collection of holders for common end mill shank sizes. Each holder mates with the R8 spindle interface and secures the end mill shank via a drawbar and set screw arrangement. The full set reduces the need to source individual holders and keeps the spindle-to-tool interface consistent across operations.

This set is intended for manual vertical knee mills and similar R8-spindle machines common in job shops, maintenance departments, and toolrooms. The range of included holder sizes supports general-purpose milling, slotting, and profiling work across a variety of end mill shank diameters. Machinists setting up a new R8 machine or replacing worn holders will find the set covers the most frequently used shank sizes in a single purchase. The set is suited for both production and prototype environments where multiple end mill sizes are routinely used.

Installation Notes

R8 end mill holders are installed and removed by a licensed machinist or trained toolroom technician. Always disengage the machine spindle and ensure the machine is fully powered down before changing holders. Holders are secured using the machine drawbar; never operate the spindle without the drawbar properly tightened. Follow the machine manufacturer guidelines and applicable shop safety procedures when handling and storing collets and holders.
