TDW
TDW Series - It is drawing block supported by hard alloy ring, polycrystalline diamond and hard alloy ring bond tightly. It is supporting ring that enhances the strength of block. This series can bear high strength drawing.
According to the drawing application
For each series we have different grain sizes of 1µm, 3µm, 5µm, 10µm, 25µm, 50µm for customer's choice. And customized sizes are available.
