Value Collection 210-2118 Milling Machine Arbor R8 Taper

Product Description

The VALUE COLLECTION 210-2118 is a stub-style milling machine arbor with an R8 taper shank, designed for use in vertical milling machines equipped with an R8 spindle. The arbor accepts tooling at a 1.25-inch diameter and measures 196 millimeters (7.717 inches) overall length. The stub style keeps the cutting tool close to the spindle nose, reducing overhang and improving rigidity during milling operations. Machinists and tool and die technicians install this arbor when mounting shell end mills, facing cutters, or similar tooling on R8-compatible machines. Weighing 3.18 pounds, this is a solid, production-grade arbor suitable for job shop and light manufacturing environments.

This arbor is intended for use with vertical knee mills, bed mills, and similar machine tools that accept an R8 taper spindle. The stub configuration is the preferred choice when minimal tool stick-out is needed for face milling, slotting, or peripheral milling operations. The 2-inch shoulder-to-nut length accommodates standard arbor spacers and collars. This part is suited for manual and CNC-converted knee mills commonly found in machine shops, maintenance departments, and vocational training facilities.

Installation Notes

Installation is performed by a machinist or qualified toolroom technician. Power down and lock out the machine before inserting or removing the arbor from the spindle. The R8 taper should be clean and free of chips or burrs before seating; use a clean shop cloth to wipe both the arbor taper and spindle bore. Tighten the drawbar to the machine manufacturer's specification and confirm the arbor is fully seated before initiating any cutting operation.
