Carbide drill


Carbide drill

This photo shows a carbide drill-bit for metal work.

Induction heating can be used for brazing.

As a titanium nitride coating has been applied to the cutting edge of the bit, the brazed connection has been made using a zinc and cadmium free silver brazing alloy BrazeTec 6488(working temperature 770°C).

BrazeTec 6488 brazing alloy is chiefly used where components have a PVD vacuum coating such as TiN and where hence zinc and cadmium containing alloys cannot be used. BrazeTec spezial h is recommended for the flux.
