100% Genuine Toyo Pistol Grip Super Cutter With Tap Wheel Head for thick glass. This clear pistol grip glass cutter features Toyo's patented lubrication system. A spring-controlled brass valve provides a smooth oil flow and a positive shut off. The unique handle provides added leverage, control and comfort. The Tap Wheel Technology incorporated in the head 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 head. The 153 degree angle wheel is designed for scoring glass from 1/4" (6.5mm) to 3/4" (19mm) thick straight cutting. Toyo# TC-600SVB.
