The QEP® Hot Dog Diamond blades are designed for quick cutting of hard tile including porcelain, ceramic, marble, and granite. This blade features a reinforced steel hub, that minimizes flexing, wobbling, and vibration, delivering exceptionally smooth and consistent cuts every time. The exclusive hot dog-shaped cutouts disperse heat during wet cutting, keeping the blade cooler for superior performance and extended lifespan. This diamond blade has a 7 mm rim height for precise cuts with less chipping, superior performance, and a longer life.
