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.
Durante la prueba de campo, las brocas tradicionales alcanzaban normalmente unos 30 metros por broca y necesitaban dos brocas para terminar un agujero, con una eficiencia media de 12,98 m/h. Con los cortadores PDC de diamante de campo instalados, la broca DTH mejorada perforó un agujero completo de 60 metros con una sola herramienta, proporcionó una mayor eficiencia de penetración y mantuvo un patrón de desgaste más uniforme. El resultado fue una reducción significativa del tiempo de sustitución y un menor coste de perforación por metro.
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.”
