The drill bit is a tool in drill, drill press and boring machines and is used to create holes in a workpiece or rock. In the operation, the drill bit rotates with the vertical axis while moving axially to complete the task of drilling.
Because the drill bits in the work will be affected by the great impact and friction, carbide tips or diamond chips can be welded to large drill bit together by induction welding equipment for shield cutter, in order to increase the strength and improve work efficiency, making the drill bit more durable.
In induction welding, carbide tips can be welded fast to the drill bit in induction heating coil of our equipment. Due to application of solder and fast induction heating speed in our machine, this induction brazing process is completed quickly and the surface of the weld place is very smooth. After induction brazing, the carbide tips on drill bit will not easily fall off and the drill bit has long service life.
