Face Discharge Natural Diamond HQ3 Surface Set Drill Bits
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.
Features:
a) In drilling soft sedimentary rocks, our natural surface bit
could be quite efficient.
b) Various diamond core drill bits (natural-surface set) are
available as well as the crown profiles, diamond grades stone sizes
and erosion-resistant features.
c) The profiles of the crown directly effects the drilling speed,
hole diameter and core recovery.
d) Multistep bit drills usually work at the fastest speed but are
less powerful in hard, broken conditions, so round or semi-flat
profiles are preferred.
