Carbide preform is a kind of carbide rod blank in a special shape which is near the final cutting tool shape, customer can customize the preform. The existence of carbide preform is due to the fact that sintered tungsten carbide is exceedingly difficult to machine and is often done using slow wire EDM or grinding, both of which are time-consuming and costly. However, before sintering, the tungsten density is low, easy to be cut, chamfered, grooved, or trimmed to different shapes, then it is sintered to be a preform with a shape close to final cutter shape, which saves lots of after-sintering machining time, cost and labor.


The T-shape carbide preform is a common preform shape, with one or more steps on the outside diameter of a carbide rod, a very big blade head end, and a short shank end.Carbide preform are customized base on customer’s drawing, sample, or final cutter shape.
