Superior efficiency in precision and time per drilled hole with hammers purpose-matched for all rock types and applications.

DTH hammers

Down-The-Hole hammers are a fast, cost efficient and versatile tools for many applications, from water well drillers to construction companies. TerraRoc’s different hammer ranges can all be adjusted for the requirement and need of different projects.

Drill safely in urban environment

How to drill in densely populated areas without damaging the existing structures around the site? Often the solutions have to be tailored for the specific work sites. DTH drilling is a popular method in both foundation works and in well and geothermal drilling. TerraRoc offers a wide range of productive and reliable drilling equipment designed for percussive drilling.

Low pressure drilling in overburden conditions

In production drilling, especially in hard rock, the use of high pressure air is vital in order to flush the drill bit efficiently. In overburden ground conditions, air from DTH drilling might unconsolidate the ground, decreasing the capacity of existing foundations. This can be an issue especially in urban areas. In geotechnical applications lower air pressure (in the range of 12–18 bar) is therefore recommended. Focus is on reliable and safe operations along with minimal environmental impact.

Terranox – cost efficient and reliable

The Terranox DTH hammers are designed for optimum performance in low pressure operations.

Reliable, well proven technology

The Terranox hammer is based on well-proven technology and over 30 years of successful operations in the industry. In urban areas drilling must usually be accomplished during restricted drilling hours. Reducing downtime is critical. Terranox hammers are rugged, reliable and easily repaired and maintained. We keep spares in stock and are ready to support you whenever necessary.

A dedicated package

The Terranox DTH hammers are very well suited for use together with our well proven casing advancement systems Symmetrix, Odex and Elemex, all committed to reliable and safe geotechnical drilling. With TerraRoc you get a unique in-house turnkey solution for your geotechnical drilling operation.

High-productive and reliable QL hammer

QL hammers have over and over again been proven to be the hammer of choice for many DTH customers. Its multipurpose use and reliability have put the QL hammer series in all kinds of applications, such as oil & gas, water well, construction, and horizontal hammer applications.

PPD120

The Utility Power Pole Drill 120 (PPD120) setup allows you to drill shallow holes from crane or other equipment where a rotation unit can be attached. A swivel with a built-in air cushion/absorber allows you to drill without the risk of damaging your crane, excavator or derrick.

Platforms

The hex connections also makes sure that the hammer doesn’t come apart and makes it easy to disconnect when transporting.
