Introduction
The Steel Body PDC Bit is designed to achieve higher rates of penetration in soft to medium hard formations with lower compressive strength.
The material of the bit adopts high quality steel and wear-resistance material with high performance is built-up welded on the surface of baldes to prevent matrix mqaterial form eroding.
Bit body is made from an integrated alloy forging and finished by advanced CNC machining center.
Deep and wide junk slots ensure bit cleaning and cooling of drilling fluid ,which benefits fast drilling and anti-balling.

Technology
Importing exclusive cutting teeth and unique curved blade design improve the ability of drilling in hard interlayer.
Features
Durasef Gauge: This incredibly strong material enhances the resistance to wear on the gauge, resulting in a longer lifespan.
Hydraulics: The hydraulic design of the bit ensures optimal movement and cooling of cuttings by matching the chip quantity and displacement of each blade.
Special Backrake Design: To prevent the bit from getting stuck during drilling, a Backrake can be incorporated into the design.
