Patented Anti-Suction Lock Technology

The patented seal design creates a vortex of air around the edge of the shroud, eliminating suction lock and allowing the grinder to float across the surface like a puck on ice. The ease of use doesn’t affect the dust collection, the shroud can still capture up to 99% of the dust. The patented polymer seal can be easily replaced without removing any other parts.
