CASE STUDY: STAGETM 3 BITS
INCREASED BIT LIFE AND REDUCED ROD TRIPPING
StageTM 3 Coring Bit 8-Month Field Results
After more than a year in the field, the StageTM coring bit has broken bit life records around the world. The design is quickly being recognized for its cost-saving operational impact.
In Sudbury, Canada, a major mine operation realized same-drill cash savings of more than $45,000 within an 8-month period – by making the switch to Stage 3 bits.

By increasing bit life, rod tripping is reduced
per shift and overall core recovery is improved. Savings are seen as the cost-per-meter falls and drill productivity improves.
