Tungsten carbide glass cutter applied for cutting window glass has the characteristics of good wear resistance, good thermal hardness (up to 900-1000 °C, maintaining 60HRC), high hardness (86-93HRA, equivalent to 69-81HRC), and its lifespan 5-80 times higher than high-speed steel.

The tungsten carbide material used in a glass cutter is sintered and formed, that is, the powder is pressed into a blank, and then heated into a sintering furnace to a certain temperature (sintering temperature), and maintained for a certain time (holding time), and then cooled down, so as to obtain the tungsten carbide material with the required performance.
What should be noted is that if the processing equipment is relatively simple, the inclination of both sides of the blade is artificially controlled, which may result in insufficient consistency, so it is best to perform it on the fixture.
