RIDGEBACK™ – Hard Rock Drilling

Rotary bits for blasthole drilling in hard rock. Specially designed shirttail to assist in rapid cuttings evacuation. High load open bearings, robust cutting structure and HET carbide treatment provide high penetration rates and long life. Vented cones (9″ diameter and up) provide for additional bearing cleaning and heat reduction.

RIDGEBACK™ products contain longer life bearings, additional gage protection and improved cutting structure elements for use in high pull-down applications.

Features and benefits

NAIL NOZZLE RETENTION
Even in the most abrasive conditions, the loss of nozzles is eliminated.

RIDGEBACK™
This patented shirttail feature allows cuttings to be removed from the hole effectively. This means reduced regrinding, faster drilling and lower total drilling costs.

REINFORCED SHIRTTAIL
A pattern of tungsten carbide inserts and welded hardmetal resist wear and protect the bearing.

MAXIMUM GAGE PROTECTION
Tungsten carbide inserts for superior wear resistance and bit life.

VENTED CONES
Standard feature on all 9" and above Ridgeback™ drill bits. Improves bearing airflow allowing cooler operation. Extends service life in high altitude applications and in areas of excessive groundwater.

ENHANCED CUTTING STRUCTURE
Robust cutting structure providing toughness in transitional ground with high ROP.

SP1 BEARING DESIGN
All Ridgeback™ drill bits incorporate advanced bearings designed to minimize over heating. The wear elements feature advanced materials to give the maximum bearing life under a wide variety of operating conditions.
