Review on Efficient 110V/250W Deluxe Tire Grooving Iron Tool for Superior Results by Sean Garrison

This cutter comes with a #4 head and blades. Its width is 3/16 inch to 1/4 inch when cutting rubber. I cut the outer grommets on my Nitto Trail grippers. The factory grooves are almost completely worn out. This makes them slightly wider than the factory. Worked great. Make sure you allow the device to warm up for the recommended time before you start cutting and move slowly while cutting. This is not a race car.
