Recommended Parameter
hydraulic flow rate 550-850 gpm rotary speed 60-350 rpm
weight on bit 4,000-14,000 lbs maximum weight on bit 24,000 lbs
Engineered Cutter Layout
Engineered cutter layout position on the bit is developed for specific applications in order to take design advantage . Cutter placement is critical in providing a total application solution.
Application Of Specific Cutters
The cutter interfaces (RAD, AXSYM and DIAX) have been developed for optimum performance in different drilling environments. These interfaces are then matched to your specific application.
Balanced Flow Hydraulics
Cutting removal and bit cooling for black diamond PDC bits are optimized by matching volume of rock removed by cutters on each blade with proportional fluid flow.
Hydrofoil Gauge Pad
Hydrofoil shape of gauge channels hydraulic fluid and cutting to annulus. This streamlined flow deters balling tendency caused by vortices and eddies.
