Advantages of PF Technology
TuffCutter replaces welded hardmetal with Bilt-In tungsten
carbide caps. Tungsten carbide is the wear resistant material
in tooth bit hardmetal. Conventional tooth bits use welding
processes requiring heat input of around 3,000F to properly
bond hardmetal to the steel tooth. Tungsten carbide begins
to dissolve into steel matrix at around 2,160F, losing
its effectiveness to resist wear. The unique PF process
with Bilt-In tungsten carbide caps controls the forging temperature to
2,100F, below the temperature tungsten carbide begins to dissolve. The
result is more effective tungsten carbide with no loss of wear resistance.
