CASE STUDY: ULTRAMATRIXTM STAGETM 3 BIT- 07UMXTM
FEWER BITS, LESS TRIPPING
Vital Stats:
• Reduced tripping frequency by more than 300%
• Increased depth drilled per shift by more than 100%
• Significant reduction in total operating costs
LESS TRIPPING, EFFICIENT DRILLING
Core drilling contracts in the large open pit copper mines of the Southwest United States
are very competitive. Drillers need to be fast and efficient, putting more core in the box in less time, to win profitable contracts. The challenge at this test site was twofold. First, find a bit with an extended life capable of significantly reducing the number of times the drillers must trip their rods. Second, find a bit that was highly versatile with increased penetration rates through all of the ground formations encountered throughout the 5,000 to 6,000 foot holes.

Reduced Tripping
“With the 07UMX Stage 3 bits, we now trip rods three times in a 5,000 foot hole as compared to the six to eight times with our pervious bit. Performance like that is just money in the bank”

Other Bits 07UMXTM
The new 07UMXTM bit in a StageTM 3, 25mm, configuration was able to easily penetrate all
of the ground conditions, and the taller crown height provided three to six times the life of the 12 millimeter bits previously used at the site. The site now averages 1,600 to 1,800 feet per bit as compared to 300 to 800 feet with previous bits. In addition, they have more than doubled the number of feet they are able to drill per shift. “It’s all about how often we trip rods, and these bits save a lot of tripping time. We not only get a significant increase in life from the bits, they are so versatile we no longer have to change a bit when ground conditions change.”
