??? 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.
