Field Diamond’s PDC Cutters Achieve 60m Single-Bit Run in Chile’s Harsh Ground
In Chile’s copper belt—known for formations with high quartz content, 8–12 rock hardness, and extreme abrasiveness—most drilling tools struggle to maintain penetration speed and tool life. The local mining team had long faced rapid bit wear and unstable drilling progress in copper ore layers containing more than 60% quartz.
To overcome this challenge, the customer equipped their DTH hammer bit with Field Diamond’s high-wear-resistance PDC cutters. The cutters’ durable diamond layer and strong thermal stability helped the bit endure heavy abrasion, while their optimized design improved cutting efficiency in quartz-rich ground. This upgrade allowed the DTH hammer bit to maintain steady performance throughout the entire hole.


Во время полевых испытаний традиционные долота обычно достигали около 30 метров на долото и требовали двух долот для завершения одной скважины, что в среднем составляло 12,98 м/ч. После установки резцов Field Diamond PDC усовершенствованное долото DTH пробурило полную 60-метровую скважину одним инструментом, обеспечило более высокую эффективность проходки и более равномерный износ. В результате значительно сократилось время замены и снизилась стоимость бурения одного метра.
The customer reported over 40% cost savings and a noticeably smoother drilling experience with fewer interruptions. As they summarized: “Using Field Diamond PDC cutters on our DTH bit completely changed the performance in Chile’s harsh copper ore—more stable, more durable, and far more efficient.”
