Core Drilling Accessories PWL / PWL3 Impregnated Diamond Core Cutting Drill Bits
1. Impregnated diamond core bit
It is most common and popular in the field of mineral exploration and geological exploration. At present, the three models (main series, navigation series and primary series) produced by our company have been recognized and recommended by many customers. Our company has selected high-grade synthetic diamond particles, which are distributed in the depth of impregnation bit matrix series. The base layer of the crown contains these crystals evenly distributed, which are embedded in the powder metal binder to improve the life and penetration rate. As the best record of our drill bit in South Africa, the life of a single drill bit reaches 614.40m.
