12mm HQ Impregnated Diamond Core Drill Bits DCDMA Standard with CE certification
SINOCOREDRILL impregnated diamond bits are manufactured using high quality raw materials for optimum drilling performance. As a result of our personnel's more than 40 years of experience in the drilling Industry,We can recommend the optimum design for optimum performance in a variety of applications and conditions. Various face profiles, bonds and diamond qualities are available for superior coring performance and longer bit life resulting in fewer trips in and out of the hole, reducing costs and improving production.
1. ISO9001certificated
2. 10years manufacturing experience
3. Super antiwear characteristic
4. Super long lifetime
5. Solid quality
The impregnated diamond bits are the most commonly useful bits in
the mineral exploration industry, as they have the widest range of
application. The carefully selected grades of high quality
synthetic diamond are distributed in the depth of impregnated bit's
matrix series. The matrix layer of the ZM contains a uniform
distribution of these crystals that are embedded in a powdered
metal bond.
The matrix of our impregnated bits is designed to expose new
diamonds to the bits cutting face as wear occurs. Fast penetration
rate is maintained as a result of this action.
Our impregnated bits are manufactured to give optimum penetration
rates and bit life, which is required to keep the cost of diamond
drilling to a minimum.
