PDC drilling tools for coal mining

PDC bits

1 .Medium Hard formation drilling

Medium parabolic profile with medium cutter density helps to obtain better ROP in medium hard formations with medium compressive strength and small abrasive layers

2 . Duraset Gauge

Super strong Material promotes gauge wear resistance to provide long bit life

3 . Hydraulics

Cutting removal and bit cooling for bits are optimized by matching the volume of rock removed by the cutter on each blade with the proportional fluid flow
