The TIGER SETJET 1.8 is used in mines, marble quarries, tunnels, and other engineering drilling applications. It features a high impact frequency at low flow rates, making it suitable for energy-efficient operations. The design is optimized by reducing the number of parts, resulting in fewer mechanical failures and lower maintenance requirements. Its hardened outer body and specially manufactured piston ensure durability in harsh working environments. The unit is engineered for easy assembly, disassembly, and servicing. These characteristics make the SETJET 1.8 a reliable choice for continuous operations in marble extraction and other precision drilling applications.
