Mining Drilling

Mining Drill Bits & Rock Drilling Equipment

In the mining industry, drill bits are the essential teeth on the excavator's jaw. They chew through rock and earth, creating holes for exploration, blasting, and ultimately accessing valuable minerals and resources. From open-pit copper mines in Arizona to underground coal operations in Pennsylvania, the right drilling tools make the difference between efficient production and costly downtime.

International Driller's Supply has been equipping mining operations since 1960. As the world's largest distributor for Mitsubishi Materials drilling products and the largest US distributor for Terelion, we supply the premium rock drilling tools that mining professionals demand. Our inventory includes DTH bits and hammers for blast hole drilling, top hammer tools for exploration and development, and a complete range of rods, couplings, and shanks to keep your operation running.

Mining Applications We Serve

Surface Mining & Quarrying

Surface mining operations demand drill bits that can withstand extreme conditions while maintaining consistent penetration rates. Whether you're drilling blast holes in a limestone quarry, an aggregate pit, or a large-scale open-pit metal mine, our DTH and top hammer systems deliver reliable performance across all rock types. We carry bits from Mitsubishi Materials, Terelion, Sandvik Rock Tools, and Boart Longyear — giving you options for every formation and budget.

Underground Mining

Underground development requires precision drifting and tunnelling tools built for confined spaces and demanding ground conditions. Our drifting product line includes bits, rods, couplings, and T-thread components designed for face drilling, bolting, and long-hole production drilling. We understand that downtime underground is exponentially costly, which is why we maintain ready stock at 5 warehouse locations for rapid fulfillment.

Exploration Drilling

Mineral exploration demands accuracy and core recovery. From initial surface sampling to deep diamond core drilling programs, International Driller's Supply provides the bits, rods, and accessories that exploration teams rely on. Our Boart Longyear product line is particularly suited for exploration applications, with diamond-impregnated bits designed for maximum core recovery in hard rock formations.

Aggregate & Dimension Stone

Aggregate producers and dimension stone quarries need consistent hole quality and bit life to maintain production schedules. Our top hammer and DTH systems are engineered for the repetitive, high-volume drilling that aggregate operations require. Whether you're producing road base, concrete aggregate, or cutting granite blocks, we have the tooling to match your application.

Mining Drilling Products

We stock a comprehensive inventory of mining-grade drilling tools from the industry's leading manufacturers:

DTH Bits & Hammers

Down-the-hole systems for blast hole drilling in surface mines and quarries. Available in sizes from 3.5" to 12" and beyond, with button configurations optimized for every rock type from soft limestone to abrasive granite.

Top Hammer Tools

Top hammer drill bits, rods, and couplings for bench drilling, secondary breaking, and exploration. Our Mitsubishi and Sandvik top hammer lines deliver industry-leading penetration rates and bit life.

Drifting & Tunnelling

Complete drifting systems for underground development — bits, rods, couplings, and shanks in R-thread and T-thread configurations. Built for the demanding conditions of underground face drilling and production.
