Wireline Diamond Core Drilling Bits / 45mm Core Drill Bit for Granite




The impregnated diamond bits are manufactured using high quality raw materials for optimum drilling performance. These impregnated bits present a metallic layer impregnated of diamonds on its cutting face. These impregnated bits are made by mixing fine diamonds with a metallic powder called matrix. The mixture is then subjected to heat treatment assuring the metallurgical bond of the matrix on the steel blank. To maintain optimal performance during entire bit life, it is important that matrix wear is synchronized with the diamond wear to ensure exposure of new diamonds with sharp edges.


As to the packing, it is first packaged by cartons, and then put into the plywood case.
