Concave Metal Drill Bit Steel Body Coal Mine Drilling Equipment
Characteristics:
1. The top surface of the bit is shallow with 3 small nozzles. and
in the circumferential direction of the blades there are 3 big
nozzles. The nozzles can rinse the bit and clean the rock debris
away from the bottom of the hole quickly. They can also prevent the
bit from being wrapped by the mud.
2. The gauge surface is inset by alloyed gauge strip which makes
the gauge highly abrasive resistant and durable.
3. The cutters (model: 1308) are parallelly inset in the blades in
symmetrical way. They are comprehensively high-performance cutters
which makes the bit better abrasive resistant and strongly impact
resistant. The rotary speed is faster.
4. The caster angle of the primary cutter can be adjusted from
16°to 20°, so the bit has the advantages of strong aggressivity,
high rate of penetration and good stability.
