Precision Tools for Every Bore Size

Geonex DTH hammers cover a wide diameter range from 4” (139.7 mm) to 33” (1320.8 mm), supporting everything from compact utility crossings to large-scale infrastructure installations. Each hammer is matched with compatible casing, button bits, and bit openers to deliver maximum impact energy and optimal flushing performance.

Designed to operate at varying air pressures and flows, they provide consistent power transfer and controlled advancement through mixed ground and rock. With options for different shank types, thread adaptors, and air consumption profiles, Geonex hammers offer both versatility and dependability for trenchless projects that require fully cased bores.
