Recommended packages
Air compressor match
KG550 air demand runs 15-35 m³/min depending on hammer — pair with a KSCY unit matched to the hammer you run (K4, K5, K6 or K8), with working pressure covering the hammer rating.
DTH hammer & bits
Supports K4, K5, K6 and K8 DTH hammers with φ76/φ89/φ102 drill rods — choose the hammer class by hole diameter, then match the compressor flow to it.
