Get into the corners big grinders can’t reach. The Inland Metal Dot Corner Wheel is a metal bond triangle grinding rasp for oscillating multi-tools — designed to grind concrete in tight corners, along edges, and in the detail areas where a planetary or hand grinder simply won’t fit. Its direct connection to the power tool eliminates the velcro overheating and falling-apart problems of stick-on rasps, and it fits a wide range of oscillating tools. Available in 30, 60, and 120 grit.

Why a Corner Wheel?
Every concrete floor has areas the main grinder can’t reach — inside corners, tight edges, spots against walls and obstructions. This triangular rasp mounts to your oscillating multi-tool so you can grind those detail areas to match the rest of the floor. It’s the tool that finishes the job the big machines start.
The Direct-Connection Advantage
Many corner rasps attach with velcro — which overheats during concrete grinding and falls apart. The Metal Dot Corner Wheel connects directly to your oscillating tool, so there’s no velcro to fail. That means a more secure hold and a rasp that holds up to the heat and demands of grinding concrete.
