Robbjack AB-1000 Slitting Slotting Saw Arbor 4 in Oal

Product Description

The ROBBJACK AB-1000 is a straight-shank slitting and slotting saw arbor designed to mount slitting or slotting saws in milling machine spindles. It accepts cutters with a 1-inch hole diameter and features a 0.75-inch straight shank for direct chuck or collet mounting. Overall length is 4 inches, with a 1-inch body length and a 1.5-inch head diameter that seats the cutter securely. A 0.25-inch projection positions the blade at the correct standoff. The arbor ships with a hex key for cutter installation. Machinists and tool-and-die professionals install this arbor on knee mills, vertical machining centers, and similar milling platforms for slotting, slitting, and parting operations.

The AB-1000 is suited for horizontal and vertical milling setups where a straight-shank arbor is required. Typical applications include cutting slots, parting stock, and producing narrow grooves in ferrous and non-ferrous materials. The drawbar thread size of 5/16-18 allows positive retention when used with compatible drawbar-equipped spindles. This arbor is appropriate for shop environments running production or maintenance milling work where consistent cutter registration and rigid tool holding are required.

Installation Notes

Installation is performed by a machinist or toolroom professional. Power down and lock out the milling machine before mounting or removing the arbor.
