Super cement drill bit (for special use, used in tungsten steel die production, high strength armored concrete)

Ultra micro-grain quality carbide materials can used to substitute Denmark cement drill bit, for special use, with good effect.
Can process to HRC64 hard alloy die, cold-heading die etc.
Batch purchase will have unexpected performance-to-price
ratio, we can also produce according to requirement of
drawings, samples, tolerances.
