9″ Grinder. Combines performance, durability and ergonomic comfort in a 9″ grinder. One of the lightest tools in its class, this grinder delivers 6,000 RPMs with its 4.0 max HP, 15-amp motor. Its spiral bevel gears transfer maximum torque to the work piece, while epoxy-coated motor windings provide extended durability. The low-profile gear case allows you to get into tight workspaces.

The grinder also features a 2-finger lock-on trigger switch, a motor access port, and a built-in aluminum tool rest. It converts easily into a sander with a 7″ or 9″ backing pad and disc (sold separately.) The tool comes with a 9″ grinding wheel, 9″ guard, side handle, flange and flange nut, nylon washer and spanner wrench.
