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≤10.
VB1308 also has excellent performance in drilling rock formations, f≥10.
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.
