The Centre has successfully designed, manufactured and supplies Nine (9) Cavity Blanking Tool for Rs.5/- with spares for India Govt. Mint, Hyderabad.  The said Blanking Tool will be working in the Schular Press Machine (Model: SAK 125) manufactured by Germany which has a capacity at a maximum speed of 500 strokes per minute. The tool consists of various parts with various materials and some of parts required heat treatment to withstand the shearing load.

There are also 9 Nos. of Tunsten Carbide and 9 Nos. of Carbide Punches in the tool. As the clearance die and punch are very close (i.e., 80 micron), the said tool required to maintain high dimensional and positional accuracy while running in high speed. Earlier this tool is used to be imported by India Govt. Mint. Tool is running successfully.
