TEI Rock Drills

What TEI Rock Drills does

TEI Rock Drills, Inc. is a privately held U.S. manufacturer of rock-drill excavator attachments, limited-access drill rigs, drilling safety equipment, and replacement components. Founded in 1980 and headquartered in Montrose, Colorado, the company designs, patents, and builds all of its products in-house at an ISO 9001:2015-certified American manufacturing facility, with core technologies centered on a patented drilling platform that pairs rugged hydraulic systems with patented drifters, rotary heads, and double-rotator configurations for use in soil nailing, micropile installation, mining, and tunneling applications. Its product portfolio includes the TD75 and TD100 Electric Track Drills (limited-access electric rigs), the HCC10X Hydraulic Casing Handler (an excavator-mounted safety attachment that eliminates manual hand-positioning of drill pipe and casing), and a full line of aftermarket drill components and parts.

The company operates a hardware-sales business model, selling equipment primarily through a structured authorized distributor network that spans North America (Western Equipment Solutions, Foothills Drilling Equipment, Selix Equipment), Australia/New Zealand, South America, Mexico, Scandinavia, Central America, South Africa, and China, with pricing conducted on a quote basis and credit/finance options available. End customers include construction contractors (primary segment), mining operators, and tunneling companies, with demand-generation supported by digital channels (LinkedIn, YouTube, website content), trade shows such as CONEXPO-CON/AGG, and an annual Hollow Bar Installation School. The company reports 11-50 employees and, on May 14, 2026, was acquired by Entegra Attachments, LLC of Saint Charles, Illinois, becoming a subsidiary within a larger attachments/equipment manufacturing platform.

Expansion highlights5 records

Broad incumbents

• Epiroc: Sweden-based mining and infrastructure equipment OEM spun off from Atlas Copco, offering a comprehensive range of surface and underground rock drilling rigs, drifters, and exploration equipment — directly competing with TEI's rock drill and excavator attachment portfolio.
• Sandvik: Sweden-based engineering group with a Mining and Rock Solutions division that includes top-hammer and DTH rock drills, rotary heads, and underground drill rigs — competing with TEI on drilling technology across mining and infrastructure applications.
• Atlas Copco: Sweden-based global industrial group with a Power Technique division offering hydraulic and pneumatic rock drills, drill rigs, and excavation equipment for mining, construction, and tunneling — directly overlapping with TEI's core product lines but at vastly greater scale and with broader portfolio breadth.

Direct peers

• Casagrande Group: Italy-based manufacturer of foundation drilling rigs, micropile rigs, and crawler cranes for geotechnical engineering — directly competing with TEI's micropile and foundation drilling products for the same contractor customer base globally.
• Soilmec: Italy-based manufacturer of drilling rigs for foundations, micropiles, ground improvement, and soil investigation — directly comparable to TEI in the foundation/geotechnical drilling segment with a similar product portfolio of compact hydraulic rigs.
• CME (Central Mine Equipment Company): US-based manufacturer of drilling rigs for exploration, geotechnical, and mining applications — comparable niche specialist competing with TEI in the mining and limited access drilling rig segment, similar in scale and customer profile.
• Geoprobe Systems: US-based manufacturer of direct-push and limited access geotechnical drilling rigs for environmental and geotechnical investigations — the closest US-headquartered direct competitor to TEI in the compact/limited access drill rig segment serving similar contractor customers.
• Klemm Bohrtechnik: Germany-based specialist manufacturer of hydraulic drilling rigs for anchors, micropiles, soil nailing, and jet grouting — closely comparable to TEI in product positioning, customer segments (geotechnical contractors), and rig-based drilling technology.

Regional players

• Furukawa Rock Drill: Japan-based manufacturer of hydraulic breakers and rock drills with strong Asia-Pacific presence — competing with TEI in rock drilling attachments and breaker equipment for mining and construction, though primarily serving APAC markets rather than TEI's NA-heavy footprint.

Others

• Boart Longyear: Global drilling services and equipment provider serving mineral exploration and production — adjacent to TEI through drilling equipment manufacturing but primarily services-led, with overlapping customer base in mining and limited overlap in TEI's foundation/micropile niche.
