TOYO’s patented Tap-Wheel Technology adds a micro-vibration as the wheel rotates, driving scores deeper with less applied pressure. The result is easier breakouts, cleaner edges, less hand fatigue and a longer lasting tool. Toyo’s Supercutters live up to their name. Comfortable to hold and easy to use, each cutter is self-oiling for a free rolling wheel and consistent score line. The wheel is made of durable carbide steel that outlasts conventional cutters. Cutter heads are replaceable. The Pistol-Grip Suppercutter lets you score glass with little effort. Get light, consistent lubrication with a refined oil-fed system. In four distinctive fluorescent colors, the lightweight clear acrylic grip lets you see how much oil is in the reservoir. Assorted colors, we apologize, color specification is currently not available. Sold individually.
