Robbjack AB-1000-1 Slitting Slotting Saw Arbor

Product Description

The ROBBJACK AB-1000-1 is a straight-shank slitting and slotting saw arbor designed to mount slitting or slotting saws for precision milling operations on metalworking equipment. The arbor features a 1-inch shank diameter and accepts cutters with a 1-inch hole diameter. Overall length measures 5 inches, with a body length of 1 inch and a head diameter of 1.5 inches. A drawbar thread size of 5/16-18 ensures secure retention in compatible milling machine spindles. A hex key is included for cutter installation. This arbor is used by machinists and tool-and-die professionals performing slotting, slitting, and groove-milling operations in job shop and production environments.

Suited for horizontal and vertical milling machines that accept a 1-inch straight shank. Typical applications include cutting slots, keyways, and thin grooves in ferrous and non-ferrous workpieces. The arbor accommodates standard slitting and slotting saw blades with a 1-inch bore. A projection of 0.25 inches positions the cutter at a controlled standoff from the arbor face, contributing to stable, repeatable cuts in both light and moderate stock-removal operations.
