HammerHead Trenchless

HammerHead® Trenchless, a Charles Machine Works Company, manufactures and delivers a unique combination of rehabilitation, replacement and installation equipment and consumables for the underground construction market. HammerHead products are sold and serviced in more than 63 countries, with worldwide sales, support, service and parts through a network of authorized dealers.

The company was established as Earth Tool Company in 1989, just a few months after co-founder Jon Haas consulted with his friend Rob Crane, a Harley–Davidson experimental mechanic, about designing a better earth piercing tool. Crane in turn invited his coworker Steve Wentworth, a Harley–Davidson product design engineer, to join him for a hands-on look at a piercing tool Haas had on hand at the time.

Although piercing tool technology had been used in the U.S. for many years, little had been done to improve its original design. Crane and Wentworth discovered the legacy piercing tool couldn’t be taken apart. They set about building a tool that was easier to use, maintain and rebuild with greatly improved performance and reliability. The result was the HammerHead® Mole, the namesake of what is now the industry’s most complete offering of trenchless pipe installation, replacement and renovation systems from a single source.

Meanwhile the design team set out to develop and improve other trenchless products such as pipe ramming tools, bursting tools and purpose-built winches and rod-pulling machines. Each reflects the fundamental principles of HammerHead’s winning formula: designs focused on quality, durability, ease-of-use, ease-of-maintenance and low cost of ownership with the ability to rebuild components for longer service life.
In 2010, HammerHead Trenchless was acquired by The Charles Machine Works, a family of brands dedicated to the design, manufacture, marketing, and distribution of a range of equipment for the underground utility construction industry. In late 2014, HammerHead Trenchless relocated its operations to Lake Mills, Wisconsin, having outgrown its Oconomowoc facilities.

Today HammerHead Trenchless solutions include a wide array of equipment and tools to install, repair or replace fiber, communication, water, sewer and gas lines with minimal disruption to landscapes, structures and traffic flow. HammerHead now offers customers the most complete array of equipment, tooling accessories and consumables for use in earth piercing, pipe bursting, pipe ramming, horizontal-direction-drilling (HDD), pneumatic HDD boring, CIPP pipe lining and CIPP point repair.

In North America, select lines of HammerHead Trenchless solutions are available through the Ditch Witch® dealer network and authorized dealers worldwide. Customers can also shop directly using the company’s online store, HammerHeadShop.com. The website provides instant access to technical sheets, manuals, videos and product literature, as well.
