Precise localized heating

Carbide (hard alloy) is used for the tips of cutting tools and drills, which are indispensable for precision machining of metals. The machining of carbide tips(blade) to install or replace worn tips is limited due to the extreme hardness of carbide.


Drill bits of various diameters (0.25" to 1.5") require carbide cutting tip machining on steel drill shafts. Brazing temperatures of approximately 1900°F (1037°C) are suitable for induction heating. Times range from 11 seconds for 0.5" diameter to 32 seconds for 1.5" diameter.

Coupling and heating efficiency are maximized in a 20kW induction heater with a set of custom 4-turn helical coils (for variable sizes).
