7 7/8''s516 PDC Drilling Bit Diamond Drill Head for Geothermal Probes

Product Description

HENGJI PDC Drill Bit

Introduction
Design for higher ROP in drilling deeper and harder formations, PDC drill bit always drills from ground to bottom directly with less or even a single run, saving large amount of drill time and cost .
Differ from tricone bit, PDC drill bit runs with lower WOB but Higher RPM, so it usually works with downhole motor to pick up rotating speed.
The performance of PDC drill bit depends a lot on PDC cutters, we provide unique solution to specific requirement on varied formations.
Steel Body PDC Drill Bit obtains better ROP in soft to medium hard formations and lower compressive strength.

Product Description

 

Features
1.Durasef Gauge: Super strong material promotes gauge wear resistance to enhance long lifetime.
2.Hydraulics: The movement and cooling of cuttings can be optimized by the hydraulic design that matches the chip quantity and displacement of each blade.
3.Special Backrake Design: A Backrake can be added in the bit in order to prevent the bit from getting stuck when drilling.

 features

1. Soft to mediun-hard formation application.

Medium parabolic crown profile and heavy cutter density provide high ROP in medium to hard formations with medium compressive strength and small abrasive layers.

1. multi-function hydraulics

The deep blade design can get high ROP in medium to hard formations and can effectively cool the bit in hrad and abrasive formations .

1. longer bit life

High intensified gage design provides for long runs on steerable system through hard and abrasive formations as teering application.
