Description

94mm PDC Well Bit Concave Drill Bit Rock Drill Bit Water Drill Bit

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.Avoiding secondary fragmentation. 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.
