It fits most air-driven low-speed grinders and stitcher tools, offering a durable cutting dome that refreshes damaged or worn areas so repair material bonds more reliably. The kit includes two 1.5\" domed buffing wheels and a threaded linking rod for quick installation and safe operation.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the Keenso buffer improve tire patch adhesion?\u003c\/h3\u003e\n\u003cp\u003eBy lightly abrading the rubber surface, the buffer creates a rough, clean profile that increases mechanical grip for repair plugs and patches.
