This head is precision CNC machined and then Nickel plated to increase operating life durability. 
 
 
The head embodies a precision ground, tungsten carbide wheel. A 134 degree angle enables the user to create sharp and accurate score lines with minimal effort. 
The combination of an extremely hard tungsten carbide wheel, ground to a sharp cutting angle, results in the Cutter's Mate Stained Glass CSG-10 Cutting Head being a superior tool for achieving glass scoring with minimal breakage or scoring defects.
