For producing flat surfaces easily there`s nothing like an oscillating lap! Our redesigned laps use a precision shaft-driven offset that produces a true orbital action of over 1300 cycles per minute. Get flat, smooth surfaces on geodes, bookends and slabs quickly and quietly, without the bounce and splash of ordinary vibrating laps. Our innovative elastomer support system eliminates all of the old-fashioned lap parts - no more springs, balls or cables! The heavy gauge welded steel frame provides great stability and won`t walk around on the floor or bench. Includes cast aluminum grind and polish pans. Comes with heavy-duty bearings & easy to level adjustable feet.
