Description
PDC drag bit/PDC concave drill bit
ABOUT PRODUCTS
Steel / matrixPDC bit is made from PDC cutter brazed to Steel Body. The PDC cutter has high hardness, abrasion resistance and toughness, provides a cutting structure for the rock formations that respond well to failure by shearing and wears by micro-chipping, the bit life is 20-40 times, the drilling efficiency is 50% higher of tungsten carbide bit.
Our products advantage
A. Selected higher quality diamond powder, improved the sintering technique, enhanced the bond combination strength between diamond grain
B.Improved the inner structure of the sintered cavity, the pressure and temperature become more balance, which ensure the cutter has more stable performance
C.Adopted a new type of carbide, which improved the weld strength
D.Optimized the designation of joint face, which reduced the residual stress
Diameter:60,65,75,94,113,133,153mm
Wings:3,4
Thread Size：As requested
Grade: Normal, Enforced, Super forced
◆Balanced Flow Hydraulic Design, avoid balling
◆High abrasion resistance, increased the bit life
◆High drilling efficiency
Applied to rock formation like granite, limestone, sandstone, mudstone,used for water well drilling, geotechnical and environmental drilling, mineral exploration, geothermal wells, geothermal drilling, construction and utility work.
Note: We also can produce and design as per clients’drawings/samples/requirements.
