The TEQ-Edge portable floor grinder from Diteq features removable panels that allow for grinding up to the edge of the wall, eliminating the need for hand grinding. The side of the head cover comes off and the adjustable axle enables the grinder to hug the wall for greater ease. Two models are available; a 2-hp electric motor or a 5.5-hp Honda engine model. The grinder comes with an 8-inch segmented grinding head. Replacement grinding heads are available in 2 grit sizes: coarse and medium grit. The unit is designed for repairing worn, damaged or spalled concrete; grinding rough uneven slab surfaces; drainage control; and grinding hard surfaces, featheredging sidewalks, gutters and similar surfaces.
