Product Description



Wireline Diamond Core Drill Bits For Granite / High Performance Core Drill Bit Geological Drilling NC3


Wedge type NQ bit has a very good fluid evacuation function.

• Helps with the removal of cuttings and debris by flushing the waterways and keeping them free and clean.



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.
