Surface set multi-step PCD diamond core bit High Grade Diamond
Product Advantages:
Descriptions:
Surface set bits are still a favoured alternative for softer
formations, or in highly abrasive ground where the balance in an
impregnated bit between matrix erosion and diamond wear would be
upset by the aggressive rock conditions.
The core drill bit with natural-surface set is mainly used to drill
relatively complete medium to high -hard formulations. There are 15
to 100 diamonds set on the matrix surface.
It's mainly made up of particles of diamonds, steel body and
carbide powder. And the diamonds are utilized for making complex
shapes of drill bits.
