Sales Standard  T38 Threaded drill bit for Drilling

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.

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.
