Availability:

Product Description

Product Specifications:

Basical Specification
Size of bit	6 1/2
Number of Blades	5
Primary Cutter Size	13mm
Nozzle Qty.	5NZ
Thread Connection	3 1/2 REG
Operating Parameters
RPM (r/min)	60~300
WOB(KN)	20~110
Application	Medium-hard to hard formations with low compressive strength, such as hard shale, limestone, sand-stone, dolomite, hard gypsum, marble, etc.

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.

2. 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 .

3. longer bit life

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

Option Features:

PDC Cutters

Different features of PDC cutters can be chosen in different wells or formations for maximizing both drill efficiency and economic

Gauge length

Short：Improved bit steerability and tool face control for directional or horizontal drilling, reduce slide section by achieve builds more quickly.

Extend：Enhances bit stability and allows more area for gauge protection components, improves bole hole quality.

Active gauge

Protect the gauge and improved hole quality
