??? WHY CARBIDE ???

There is great difference between cutters made from
carbide or tungsten carbide and those made from 'high speed' or 'high carbon' steel.
High speed or carbon steel is not as hard as carbide and therefore its ability
to maintain a sharp edge is drastically reduced. It may work fine for the first
few jobs, but as it begins to lose its edge it
quickly falls into a downward spiral.



As the cutting edge dulls it rubs rather
than cuts the metal, which generates friction and heat buildup. The buildup of
heat weakens the metal, which leads to more dulling and more heat, etc., and
soon the cutter is worthless. How many times have you been trying to grind off a
rivet head on a case latch while watching the metal turn red hot and start to
melt the plastic on the case!



Carbide provides smooth, rapid removal of metal. And from an economical
viewpoint, one carbide cutter will easily outperform and outlast many cutters
made from high speed or carbon steel.
