The central part of the drill bit consists of cutting edges that rotate around the center. The shape of the plates has a back angle. During drilling, the cutting edge becomes dull and must be sharpened. To do this, you need to use a grinding machine and green silicon carbide wheel.
Brazing of carbide plates is performed using an induction heating unit.
To improve flushing, we make a beveled edges, that reflect the water jet into the cutting zone.
To connect the drill bit with a drill rod you can use an adapter. It is included to kit with each drill bit.
The adapter has a ready made thread for drill bit connection. On the other side you can make your thread for drill rod connection. This is an adapter for threading.
