This size of hammer, which is mainly used in construction projects for consolidation and in open-pit mines for drilling and blasting, is produced in two models:

DS4: Designed for drilling rigs with conventional compressor pressure. This hammer, having reached full maturity in design, has the highest efficiency, the most appropriate speed of operation and the least amount of damage among all hammers available in the market.

DS4 Extreme: This hammer is suitable for powerful drilling rigs with high-pressure compressors. The high speed of operation and penetration rate are the result of the innovative design of this hammer. Its excellent durability and resistance to wear and tear are due to the use of high-quality raw materials and production processes. The 4-piston has a reversible feature and can be reversed when needed.
