Each mixture is designed to give the carbide a particular balance of hardness and toughness also impact and wear resistance that suits a particular type of machining application — a saw blade to rip hardwoods or composite materials; a router bit for shaping plastics, etc.
The metal powers are carefully measured, then mixed together and combined with alcohol. They are then poured into a large Ball Mill — a sealed spherically-shaped tank filled with stainless steel balls that agitate the mixture kilograms at a time.
The ball mill runs for anywhere between 36 and hours and creates a muddy-looking sludge. After the steel balls are removed, the sludge is transferred to a spray plant — an even bigger steel vessel that resembles a huge dust collection cyclone. The spraying action inside the device evaporates liquids and turns the sludge into zillions of perfectly round, homogeneous droplets.
These teeny carbide balls are between. Next, a tumbling machine smoothes the surface of each ball-like droplet. Smoothing is necessary because the metallic powder must flow freely when it is next poured into tiny molds — one for each little carbide saw blade tooth or router bit insert or shaper knife.
Special automated machines make these teeth, dispensing exact amounts of carbide powder into short rows of molds, then pressing the powder to compact it to give it enough density for it to keep its shape when the tooth is pushed out of its mold. Many dozens of press-molded tips are deposited onto metal trays, which are stacked into holding frames. At this rate of production, the plant churns out around million saw blade tips a week! Next is the most crucial step in the carbide-making process: Sintering permanently transforms the molded greenwork into solid carbide teeth ready for the rigors of woodworking.
If you were to simply heat the powder until all the disparate metals melted, some would evaporate before others had dissolved completely. To put it a different way, sintering carbide is like shaking the salad dressing bottle; the agitation gets the oil, water and vinegar to combine into a well blended mixture.
Proving their commitment to product quality, every Freud woodworking and cutting tool is backed by a lifetime satisfaction guarantee. Any manufacturer willing to put their reputation on the line like that certainly has a number of supporters, and Ohio Power Tool is one of them. Freud is also one of the few manufacturers of woodworking tools in the world that produces its own MicroGrain Carbide with Titanium, called TiCo, a combination of Titanium and Cobalt.
Freud develops different types of carbide for each application to maximize the cutting life and performance of the tool.
Because our customers demand a lot from their power tools, Ohio Power Tool is proud to carry a wide selection of Freud router bits and Freud saw blades. The Freud router bits and shaper cutters we offer include everything from flush trim router bits and straight edge cutters to double flute router bits and door lip cutters. The Freud saw blades we offer include several Diablo options cement saw blades, composite saw blades, metal saw blades, polycrystalline-diamond PCD saw blades, reciprocating saw blades, and wood saw blades , as well as industrial wood saw blades.
