BQ,NQ,HQ,PQ Wireline Impregnated Diamond Core Drill Bit for Mineral exploration
Introduction:
The unique protrusions on the face of the bit contain diamonds that enable the bit to begin cutting right out of the box – even in the softest ground. The arrangement of these protrusions also improves the tracking and balance in the hole when drilling begins.
Typical diamond coatings do not create a chemical bond, due to the strong oxide on typical titanium coatings, leading to the same 40% diamond projection as mechanical bonding. As a our bit is drilling and the matrix wears down around the bottom, the diamond stays in place longer and acts like a bigger diamond, which results in more meters per bit.
