Quality groover cuts clean, smooth professional control joints every time. A unique tool won't wear out with extended use in concrete like steel groovers. The single-piece casting insures strength and a quality surface. This concrete groover blade is hand-polished for a smooth professional finish every time. This tool creates a groove in wet cement to control expansion and contraction and relieve stress points. The groover creates a 1/4" radius to prevent the edge of the groove from chipping. This 7-1/2" groover features a bit that is 1/2" wide and extends to 1-1/2" deep. The deep bit extends out from the base to provide ease to the user in moving through the concrete. The closed-end groover bit eliminates build up within the tool. The 4-1/2" wide tool provides coverage for control joints on projects large and small. The strong construction allows for work on hard material such as pervious concrete. The comfortable ProForm® soft grip handle is secured to the casting. The enhanced texture on the handle reduces fatigue and provides a great grip even when wet. The signature orange and black handle is easy to find on a jobsite.
