Robbjack AB-500 Slitting Slotting Saw Arbor

Product Description

The ROBBJACK AB-500 is a straight-shank slitting and slotting saw arbor designed to securely mount slitting or slotting saw blades on milling machines. It features a 0.5-inch shank diameter and an overall length of 2.875 inches, making it a compact, rigid tooling solution for precise slotting and cutoff operations. The arbor accepts cutters with a 0.5-inch hole diameter and includes a hex key for blade clamping. It is well-suited for manual and CNC milling setups where consistent blade positioning and minimal runout are required. A licensed machinist or tooling technician typically handles installation in a machine shop environment.

This arbor is intended for use in milling machine applications requiring slitting or slotting saw operations. It fits standard vertical and horizontal milling machines that accept a straight-shank toolholder. Typical applications include cutting narrow slots, parting operations, and undercutting tasks in metalworking and general machining. The 0.25-inch projection and 0.75-inch head diameter provide clearance geometry suited for shallow-to-moderate depth slotting cuts.

Key Features

• Straight shank design with 0.5-inch shank diameter for direct spindle or collet mounting
• Accepts cutter hole diameters of 0.5 inches for standard slitting and slotting saws
• 0.25-inch cutter projection provides controlled blade exposure during cutting operations
• 0.75-inch head diameter and 0.375-inch body length support secure blade seating
• 1/4-20 drawbar thread size for positive cutter retention
• Includes hex key for on-machine blade changes

Compatibility

Designed as an OEM-style tooling arbor for milling machines that accept a straight-shank arbor with a 0.5-inch shank diameter and use slitting or slotting saw blades with a 0.5-inch cutter hole diameter.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Power down and lock out the milling machine spindle before mounting or removing the arbor. Ensure the collet or spindle bore is clean and free of debris before inserting the straight shank. Use the included hex key to secure the cutter blade firmly against the arbor head before resuming machine operation.
