International Driller's Supply maintains operations in Fredericksburg, Pennsylvania, providing drilling contractors, quarry operators, and construction companies across the Northeast with fast access to the premium rock drilling equipment they depend on. As the world's largest Mitsubishi Materials drilling parts distributor and the largest US distributor for Terelion, our Pennsylvania presence puts industry-leading products closer to the jobsites that need them most.
From our Fredericksburg location in central Pennsylvania's Lebanon County, we serve the entire Commonwealth and the broader Mid-Atlantic and Northeast regions — including New Jersey, New York, Maryland, Delaware, and West Virginia. Whether you're operating a crushed stone quarry in the Lehigh Valley, drilling bridge foundations for a PennDOT project, or installing environmental monitoring wells at a remediation site, we carry the DTH bits, hammers, top hammer tools, drifting and tunnelling equipment, and accessories to keep your operation running.
Pennsylvania is one of the nation's top producers of crushed stone and aggregate. From granite and limestone quarries in the Lehigh Valley to trap rock operations across the Piedmont region, quarry operators demand durable DTH and top hammer tooling built for high-volume production. Our Mitsubishi, Sandvik, and Terelion products deliver the penetration rates and bit life that keep quarry operations on schedule across the Commonwealth.
Pennsylvania's extensive highway system — including the Pennsylvania Turnpike, I-76, I-80, and I-81 corridors — requires constant geotechnical investigation and foundation drilling. PennDOT bridge replacements, slide corrections, and new highway construction all depend on reliable drilling equipment. We stock the tools that PennDOT-prequalified drilling contractors count on for test borings, micropile installations, and foundation work across all 67 counties.
Pennsylvania's industrial legacy means ongoing demand for environmental site investigation and remediation drilling. Monitoring well installation, soil and groundwater sampling, vapor extraction, and injection well construction all require specialized drilling equipment. Our inventory includes the drill rods, bits, and accessories used by environmental drilling contractors throughout the Commonwealth — from former industrial sites in Pittsburgh to Superfund cleanups in the Lehigh Valley.
Philadelphia, Pittsburgh, and the Lehigh Valley corridor are among the most active construction markets in the Northeast. Commercial development, residential construction, and infrastructure projects all require foundation drilling through Pennsylvania's diverse geology — from coastal plain sediments in the southeast to Appalachian shale and sandstone in the west. Our top hammer and DTH products handle it all.
We carry a comprehensive inventory of rock drilling equipment and parts from the industry's most trusted manufacturers:
Down The Hole bits and hammers for mining, water well, construction, and quarry applications. Available from Mitsubishi Materials, Sandvik, Center Rock Inc, and Terelion.
Complete range of top hammer drill bits, rods, shanks, and couplings for surface and underground drilling. Mitsubishi Materials, Sandvik, and Boart Longyear product lines in stock.
Specialized drifting and tunnelling rock drill accessories for underground mining and civil construction.
Replacement parts, service kits, O-rings, retainer rings, check valves, and wear items to keep your drilling equipment running at peak performance.
