8"x12" 3/4"D 1/4"R Orange Thunder® with KO-20™ Technology Square End Groover

The unique walking groover is designed to create control joints in concrete. KO-20™ material allows the blade to move effortlessly across the surface as it moves the 8" aluminum groover bit through the cement. The closed end bit prevents build-up and provides strength to move aggregate to form a perfect groove. This groover bit is 3/4" deep. The bit has a 1/4” radius for smooth edges that won’t chip. A sight helps guide the user to create perfectly straight grooves. The 12” wide blade has square ends to work along forms and into corners. Impact, chemical, corrosion, and rust resistance allow for a long tool life. Steel bar with aluminum bracket runs across the top of the bit providing support. Use with clevis handles or adapters. Hardware for bracket is included.
