Thread drill bits are made by high quality alloy steel bar 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.

In addition, 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.

 

New Design Uniface Bit Face Degign

The Uniface comprises a series of three new, patent-protected universal bit-face designs,

one for Ø51-64mm bits;
one for Ø
70-96mm bits;
one for Ø
102-152mm bits.

 

The guidelines for choosing the right Uniface bit are:

1. spherical buttons for very hard rocks;

2. ballistic buttons for less-hard rocks;

3. regular bit-skirt for solid homogenous formations;

4. retrac skirt for mixed, jointed or fractured formations.
