The Hum-B can cover more square footage in less time, with less effort while focusing on comfort. The ergonomic design allows the user to work standing upright, getting them up off of their knees and reducing fatigue, backaches, and job site injuries. The Hum-B is ideal for concrete, terrazzo, stone, and removing paint, thin-set, adhesives, VCT, mastic and epoxy. The Hum-B is the only edge grinder with the patented Dust Grabber™ shroud. This shroud allows the grinder to float across the surface like a puck on ice, eliminating suction lock and capturing 99% of airborne dust.

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.
