Value Collection SA/R8 Slitting Slotting Saw Arbor R8

Product Description

The VALUE COLLECTION SA/R8 is a slitting and slotting saw arbor designed for use in milling operations on R8-taper spindle machines. It features a taper shank with an overall length of 5 inches and an arbor diameter of 1.259 inches (32.0 millimeters). The shank diameter measures 0.945 inches (24.0 millimeters). This arbor accepts cutter hole diameters of 1/2, 5/8, 3/4, 7/8, and 1 inch, making it compatible with a wide range of slitting and slotting saw blades. The projection from the spindle nose to the arbor face is 53.3 millimeters. An Allen key is included. Machinists and toolroom technicians install this arbor in manual or CNC knee mills and vertical machining centers equipped with R8 spindles.

This arbor is suited for slitting, slotting, and parting operations in metalworking, fabrication, and toolroom environments. It fits standard R8 collet-style spindles commonly found on Bridgeport-style knee mills and similar vertical milling machines. The multiple cutter hole diameter options allow one arbor to be used across a variety of saw blade bores, reducing the need for multiple dedicated arbors on the shop floor.
