Ridgeback D-Force™ Blasthole Bits |
 |
Durable. Dependable. Determined.
Ridgeback D-Force series bits are engineered for highly abrasive and broken ground applications often found in gold bearing formations, as well as some copper and coal bearing formations. D-Force products feature longer-life bearings, heavy duty shirttails, a unique Sidewinder leg design, enhanced air flow system and improved abrasion resistant tungsten carbide inserts, providing added durability and increased penetration rates under a wide variety of operating conditions. D-Force bits are currently available in 6-3/4" (171 mm) through 16" (404.4 mm) sizes.
D-Force features include:
- Advanced bearing package - Designed to minimize heating and provide maximum bearing life
- Enhanced shirttail protection - Abrasion resistant semi-round top (SRT) inserts set into the Varel Sidewinder design create an extremely strong gage beneficial for holding gage while drilling ahead
- Improved cutting elements - Varel's patented High Energy Tumbling (HET) method produces a unique cutting structure surface that extends bit life and increases drilling rate
- Vented cones - Standard in all D-Force series bits 9" and larger in diameter, vented cones allow a continuous air flow throughout the bearing to provide better cooling and cleaning
- Increased hole wall clearance - Keeps the bit body away from the hole wall with raised shirttail inserts, improving evacuation of large cuttings and reducing abrasive wear on the bit body
The D-Force advantage:
- Longer bearing life
- Increased penetration
- Added gage penetration
- Reduced heat generation
- Larger cuttings
- Less dust
