100% Genuine Toyo Replacement Custom Grip Glass Cutter Narrow Head. Designed for Toyo Custom Grip Supercutter models TC21P.
 
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. Wheel hone angle is 140 degrees.
 
The narrow head is designed for pattern glass cutting.
