Carbide Preform, Cutter Preform, Carbide Cutter Preform, Net-To-Shape Carbide Cutter Blank

It is difficult to machine the carbide blank after sintering because of its very high hardness, lots labor, high grinding wheel wear rate, lots machining time, and blank waste when unqualified machining happens. In this situation, the net-to-shape carbide preform is required. We custom the shape near your cutter before sintering and after press or extruded, it is not big cost to do the grinding or shaping before sintering, but can save you lots time and money in post sintering machining.

T shape preform is the common preform style, the bigger step of the T cutter has, the more economic to get carbide preform instead of getting carbide rod blank.
