High Performance Button Bits Rock Drilling 127mm T51 With Spherical Buttons

High Performance 127mm T51 Thread Drill Bit for Rock Drill Bit with Spherical Button

Thread Button bits are made by alloy steel bar of quality and tungsten carbides.

Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks.

Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock:

(1)Thread: R22, R25, R28, R32, R35, R38, T38, T45, T51, ST58, T60

(2)Diameter: 38-127mm.

How to choose the bit tooth type:

Spherical buttons: The height of exposed teeth is low, mainly used in the very hard rock formation above F14, to improve wear resistance, to prevent the situation of debris, it should take lower drilling speed.

Ballistic buttons: It can expose more height of buttons, mainly used in soft rock and ordinary rock below F12, with quicker drilling speed, but encountered hard rock, very easily to happen buttons debris phenomenon.
