Carbide Knives
Cut-off knives and cut-off bushes should never be omitted in any cold working operation. They
enable the capacity of the machine to be better utilised and reduce the production cost. Cut-off knife
cuts the wire uniformly clean even in a large quantity of production and thereby the need for constant
attention to check the burr formation is avoided. Due to the burr free cut surface of the wire, the life
of the cold heading tools is simultaneously increased.
