8 in. x 8 in. 1/2 in. R 3/4 in. D Stainless Steel Walking Groover with no bracket is a strong groover that cuts clean, smooth professional control joints every time. Made from high quality #18 gauge stainless steel. Both sides of the groover are curved up to avoid any gouging while in use. The tool creates a groove in wet cement to control expansion and contraction and relieve stress points. The 8" groover features a 1/2" radius and is 3/4" deep. The single-piece formed groove provides a smooth professional finish. The closed end groover bit eliminates possible build up within the tool. Each Groover is made from hand polished stainless steel that won't rust for an extra smooth working surface. The rivet free design combines an 8" wide groover base, and top plate electronically welded together providing strength to move through concrete. Four bolts protrude from the base to accept a 4-hole bracket of the user's choosing. The Kraft Tool Co.® EZY-Tilt® II Bracket (#CC294) is recommended. Proudly made in the USA.
