HSS fully ground jet point tip drill bits
The jet point tip drill bits can reduce drilling resistance and its axial force reduces nearly 30% and torque reduces 15% compare with normal drill bits.
The jet point tip of the drill bits can decrease drilling hear and lower temperature of cutting edge.
The jet point drill bits performs 3-5 time productivity than normal bits.
It is 10 times faster starts cut into work pices for this kind of drill bits, and which have more good centering ability.
