PDC
cutter consists of PCD layer integrally sintered at ultrahigh
pressure and high temperature to a cemented tungsten carbide
backing. They have high hardness, wear (abrasion) resistance and
impact resistance, are widely used for oil/gas drilling, geology
exploration and mining, applied to soft to medium hard formations.
And also could be used be on some grinding tools and wear resistant
parts.
Standard Size:***4,***4,***4,***6,***8,***4,***8
PDC cutters
forrock drilling, coal mining bits and diamond
tools.
We have VA,VB and HM
series of cutters available.
VA series for rock
drilling, coal mining bits and diamond tools
(normal)
VA cutter is the most
mature in technology and stable in quality.
Feature: good abrasion
resistance, excellent impact resistance, high rate of
penetration
Usage: anchor shank
drill bits, stepped side cuffed core bits, core
bits.
Application: coal
measure stratum and rock formation.
VB series for rock
drilling, coal mining bits and diamond tools
(forced)
VB cutter is improved
from VA series, it’s adopted series of new technologies, its
abrasion resistance is enhanced greatly, the impact resistance is
same as VA cutter, now it has become the first choice in the middle
and high market in domestic market.
Feature: high abrasion
resistance, excellent impact resistance
Usage: forced anchor
shank drill bits, forced core bits, forced non-core
bits.
Application: medium hard
formations, f≤*0.
VB***8 also has
excellent performance in drilling rock formations,
f≥*0.
HM series for rock
drilling, coal mining bits and diamond tools
(super-forced)
HM cutter is the top
product, through lots of research and tests, we improved the
manufacture technology successfully, and the quality become more
and more mature.
Feature: high impact
resistance and abrasion resistance, medium rate of
penetration
Usage: super-forced core
bits, super-forced non-core bits
Application:
conglomerate, granite, quartz, sandstone.
