2.5.2024 | Robit® H Series DTH Hammers
Robit has developed a completely new, modular H series hammer family for DTH drilling.
The H series hammer range currently consists of four different sizes: 4, 5, 6, and 8 inches. Thanks to its unique modular structure, with just a few part changes, customers can get 12 different variations to meet their specific needs. DHD versions are primarily intended for construction and well drilling, while QL versions are thicker in their outer casing, designed as Heavy Duty hammers suitable for quarrying and production use. Released hammers use either drill bits with foot valves or tubeless versions, allowing the use of drill bits without foot valves in challenging drilling conditions.
H series benefits:
- Up to 25% lower fuel consumption
- Best in class performance
- Unbeatable for all conditions

- Robit® DTH Hammer H4 API 2⅜IN Reg Pin
- Robit® DTH Hammer H5 API 3½IN Reg Pin
- Robit® DTH Hammer H6 API 3 ½IN Reg Pin
- Robit® DTH Hammer H8 API 4 ½IN Reg Pin
The assemblies vary between Maximum Performance (MX) and High Efficiency (HF), as well as Foot Valved (FV) and Tubeless (TL) versions of the same Heavy Duty (HD) or Slim Line (SL) hammer. The Maximum Performance assembly offers a high blow energy obtained by high air volume, resulting in a fast penetration rate, and is suitable for deep-hole drilling. The High Efficiency assembly operates on a lower air volume, providing lower blow energy but a higher frequency, keeping the hammer energy efficient, and is ideal for softer or varying ground conditions.
