Varel Tricone blast hole bits
Read the complete Varel brochure.
DPSA Mining Products distributes Varel International's Ridgeback Marathon™ series of 3 cone bits. These products are specifically designed for the blast hole industry and feature the most advanced features available today in air circulation rock bits.
- Ridgeback™ Design Technology software enables design changes to be introduced rapidly, aids the engineer with bit design analysis and includes such factors as drill operating parameters, bit geometry and mine lithology. Varel engineers are able to predic
t the effects of design modifications and limit the risks associated with new product development. - Advanced Bearing Design minimises heating. The wear elements feature advanced materials to give the maximum bearing life under a wide variety of operating conditions. Extended bearing life is achieved by the use of specialised rollers, newly designed tungsten carbide thrust buttons, and premium quality “clean” steel.
- High Energy Tumbling™ gives precision manufactured inserts a unique surface toughness that extends bit life.
- Improved Thrust Capacity minimises outward thrust wear and prolongs bearing life.
- Enhanced Cutter Design provides the highest penetration rates and longest life available.
- Maximum Gage Protection - SRT (Semi Round Top) tungsten carbide and welded hardmetal provide superior wear resistance to the shirttailarea. This feature is particularly effective in formations which tend to cave in, or when hole bailing is a problem.
- Vented Cones are standard in all Ridgeback™ and Ridgeback Marathon™ series bits 9” and larger in diameter. Vented cones allow a continuous air flow throughout the bearings to provide better cooling andcleaning.
