The groover's precision guide wheels track in the seam to cut a groove for heat welding. Groove starting at the middle of the seam with the front blade, then up close to the wall with the rear blade. Groove curves and circles using a clip-on foot plate that allows the back end to slide. Blade depth is adjustable. Cuttings flow out under the handle, which pivots open for cleaning. All adjustments are made with a 1/8" hex key (included) that stores on the tool. Takes standard blades and comes with two No. 974 4mm blades. Comes with protective bag.
