Retrac/Standard/Straightrac Button Rock Bits Thread
R32/R38/T38/T45/T51 for Tunneling1. Made by high quality alloy
steel bar and tungsten carbides. Through heat
treatment, they are tough enough to meet rock drilling demands and
have the least loss of energy while drilling the rocks. 2. In
addition, customized thread button drill bits are available
according to different drilling application, and custom drill bits
are applicable to drill soft rock, medium hard rock and hard
rock. New Design - Uniface Bit Face
DegignThe Uniface comprises a series of three new,
universal bit-face designs, one for Ø51-64mm bits; one
for Ø70-96mm bits; one for Ø102-152mm 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.
