Recommended packages
Air compressor match
This rig draws 15-22 m³/min at the hammer. Pair it with a KSCY-650/20-700/17T (18-19 m³/min dual-mode 2.0/1.7 MPa) or the next class up, keeping 10-15% flow margin.
DTH hammer & bits
K5/K50 class hammers (135-165 mm) suit the Φ105-152 mm range of this model — confirm the hammer pressure rating against your compressor before ordering.
