Value Collection 210-0110 End Mill Holder R8 Taper

Product Description

The VALUE COLLECTION 210-0110 is an R8 taper shank end mill holder designed for use in milling machines equipped with an R8 spindle. The holder accepts end mills with a 3/4 inch shank diameter and provides a projection of 60 millimeters from the spindle face to the tool tip, giving machinists consistent gage length for setup. The R8 taper is a widely used standard in Bridgeport-style vertical knee mills and similar manual milling machines found in job shops and maintenance departments. This holder is installed by machinists and toolroom technicians performing milling operations on ferrous and non-ferrous materials.

This end mill holder is suited for manual vertical milling machines with R8 spindles. The 3/4 inch bore accommodates standard 3/4 inch shank end mills secured by a drawbar through the spindle. The 60 mm projection is appropriate for general-purpose milling work where moderate tool reach is required. No through-coolant feature is present, making this holder best suited for dry cutting or flood coolant applied externally at the cutting zone.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before installing or removing any tool holder, power down the milling machine and verify the spindle has come to a complete stop. The R8 holder is secured using the machine drawbar — tighten the drawbar to the machine manufacturer's recommended procedure before engaging the spindle. Inspect the taper shank and spindle bore for chips or contamination before seating the holder, as debris will prevent proper taper contact and can cause runout.
