Product Description
HWL3 (HQ3) Impregnated Diamond Core Drill Bits
The impregnated diamond core bits are the most commonly used bits in the mineral exploration industry, offering the widest range of application. Carefully selected grades of high-quality synthetic diamond are distributed throughout the depth of the impregnated bit's matrix series. The matrix layer of the crown contains a uniform distribution of these crystals embedded in a powdered metal bond.
Advanced Matrix Technology
Our impregnated bits are engineered to expose new diamonds to the cutting face as wear occurs, maintaining fast penetration rates throughout the drilling process. This self-sharpening mechanism ensures optimal performance and extended bit life.
