Tire Grooving Tool Heads for Most Common Grooving and Siping Jobs

A heated tire groover is a great tool to have in a racer’s toolbox. Tire grooving and tire siping can be just the advantage you need for your race car’s tires to help you end up in the winner’s circle after a long night of racing on the dirt. Be sure and have the correct tool head and plenty of blades in your race car’s trailer at the ready trackside for grooving tires and siping tires. We carry a full lineup of cuttingblades for these tire grooving iron heads too. Don’t forget you’ll want to install the head and set the blade to the depth of cut needed before plugging in the groover!
