BQ NQ HQ PQ Mining Tools Diamond Impregnated Drill Bit
Diamond core bits products include: 1,drill bit: Impregnated diamond diamond drill bit, sufface set diamond drill bit, electroplated diamond drill bit, tc drill bit, PCD drill bit, thin wall drill bit; Hole: alloy reamer, polycrystalline reamer, electroplated reamer,surface set natural diamond reamer;
Impregnated diamond bit:
The impregnated diamond bits are the most commonly useful bits in
the mineral exploration industry, as they have the widest range of
application. The carefully selected grades of high quality
synthetic diamond are distributed in the depth of impregnated bit's
matrix series. The matrix layer of the crown contains a uniform
distribution of these crystals that are embedded in a powdered
metal bond. The matrix of our impregnated bits is designed to
expose new diamonds to the bits' cutting face as wear occurs. Fast
penetration rate is maintained as a result of this action.
The matrix layer of the impregnated diamond core drill bits crown
contains a uniform distribution of these crystal diamonds that are
embedded in a powdered metal bond. The main technical parameters of
impregnated diamond core drill bits are diamond specifications,
like type, size, concentration and grade, as well as matrix
hardness type and crown shapes, which are selected according to the
hardness and abrasiveness of the formation to be drilled. If user
can make rational selections according to the rock formations, then
they can get satisfied drilling performance on various formations
with different hardness.
Product Advantage:
1. Impregnated Diamond Bit: Special mental coated diamonds to
extend the diamond working life.
2. Surface Set Diamond Bit: Choose natural diamond with the fast
drilling speed, espencially used for soft, abrasive and
unconsolidated rock formation.
3. Matrix Height: 7mm-25mm, provide better drilling speed and
drilling life.
4. Drill Bit Design: Standard V-ring,Turbo, Face discharge, Flat
face, Stepped, Vortex type,Pilot type, etc.
