API Newest PDC Oil drill Bits - size 3-3/5" to 26"

Newest PDC Oil drill Bits

1)These bits are designed for high speed drilling in shale, limestone, and sandstone formations.

2)Unlike roller cones, these PDC bits are a one piece matrix bodies with no moving parts. The fixed-cutters shave away the rock, making it possible to operate with higher rotation speeds more efficiently in consolidated formations.

Hejian Fanglei Drill Equipment Co., Ltd was founded in 1990, and is one of the most professional companies that specilizes in the drilling equipment. We can supply a large quantity of new and used pdc bits, tricone bits, drill pipe and drill collar etc, and various size is available. Besides, the goods have good quality and reasonable price you are interested in drill bits, please contact me now for a long time. We are waiting for cooperating with you and your company sincerely.

Structure features and applications of the bit:

1. Optimally designed bit profile suitable for drilling medium formation.

2. Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced

which resulting better stability of the bit.

3. Multiple types of high performance PDC cutters are strategically arranged on bit for improved service life

of the bit.

4. Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.

5. Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance cleaning

and cooling effects of the bit to effectively prevent bit from balling.
