Pro-Graad Replacement Lap Machine Arbor, Fits Hi-Tech All-U-Need & Cabber

The Pro-Graad Lap Machine Arbor provides a reliable replacement for worn or damaged arbors on compatible lapidary equipment. Designed for use with All-U-Need flat lap machines and Slant Cabber machines, this arbor fits both 6-inch and 8-inch models and securely holds compatible diamond discs and laps during grinding, shaping, sanding, and polishing. The arbor mounts directly onto a 3/8-inch motor shaft and features a 1/2-inch top diameter for laps and diamond discs with 1/2-inch arbor holes. An integrated set screw helps secure the arbor firmly to the machine shaft. Installation and removal are straightforward using a 1/8-inch Allen wrench to tighten or loosen the set screw. Over time, an original lap machine arbor may experience wear that can contribute to unwanted movement or wobble during operation. If you have already narrowed the source of excessive disc or lap wobble to a worn arbor, replacing it can help restore proper mounting, alignment, and smoother rotation. This makes it a practical replacement component for maintaining older machines and extending their useful service life. Built as a direct replacement solution, the arbor allows you to continue using your existing compatible diamond laps and discs without replacing the entire machine. Please verify your machine model, 3/8-inch motor shaft, and 1/2-inch lap arbor hole before ordering. Package includes one replacement lap machine arbor with installed set screw and 1/8” allen wrench.
