Over 45 years has led to ingrained RC expertise. Our founder, Art Holte, remains one of the most gifted innovators and experts in the field of RC Drilling technology. Art’s emphasis on comprehension of the complete RC drilling system, and a relentless standard to make high quality tooling, have pervaded the company. We grow with the needs of the industry—not shareholders. Our sales and design teams have literally machined, assembled, and used RC drills. We’ve modified drill rigs to work with RC. Our offices are still on the manufacturing floor where we can hear the sweet sounds of CNCs and testing hammers; where machinists, sales, and designers can interact to make sure our drilling tools lead the industry.

Holte manufacturing began making Top Heads 25 years ago when it became clear that existing products on the market were not meeting the needs for RC drilling. Holte started machining gears and the RC Top Head Drive was born.

Over the last quarter century, our design has matured to be durable, dependable, and straightforward for easy maintenance. Top Heads are customizable for reverse circulation, grout through systems, tilting heads, and more.

The compact, yet powerful, 3000 series fits into the mast of smaller drill rigs. The 3000 features a continuous torque rating of 18,000 ft/lbs with intermittent operation up to 28,000 ft/lbs.
