Parabolic Diamond Drill Bit For Mine Coal Drilling Tools
Characteristics:
1. The crown surface of the bit is medium cast surface which
makes the bit suitable for medium hard to hard and strong abrasive
formation.It can used in high rotation speed operation.
2. The design of medium cast surface has the advantages of good
stability,good guidance quality and strong impact resistance. There
are 3 nozzles in the conical surface which can clean the bit better
and clean away the rock debris so that the cutters will not be
repeatedly used to cut rock debris during the drilling.
3. The cutters are symmetrically inset in interlaced way to cut the
rock encompassingly with the caster angle of 15°to 20°. So the bit
has high rate of penetration and good stability.
4. The gauge surface is inset by double-row alloyed gauge strip in
separating way which makes the bit have strong abrasive resistance
and good gauge effect.
5. The angle of the 3 blades is different, so the fluid rock debris
can expel from the hole quickly and the bit will not be wrapped by
the mud when it drills in a high rotary speed. The efficiency will
be improved.
