The Arbe PM-350 is an American-made variable speed polishing motor built for professional jewelers and metalsmiths in the USA jewelry industry. Delivering smooth, controllable power from a 1/2 HP motor, the PM-350 gives you the flexibility to dial in exactly the right speed for every polishing task — from delicate finishing passes to aggressive buffing. The wide speed range of 0–3600 RPM means you can work confidently across a broad range of materials and buff types without changing equipment.

Designed with practical bench dimensions in mind, the PM-350 measures 16.5 inches tip to tip across the included spindles, with a shaft height of 7 inches to the tip of the tapered spindle — giving you ample clearance for a variety of buff and wheel sizes. Both left and right tapered spindles are included, so you can mount different compounds or buffs on each side and move efficiently through your polishing workflow.
