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.
Description:
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.
