Recommended packages
Air compressor match
This rig draws 10-17 m³/min at the hammer (3" or 4"). The standard pairing is a KSCY mobile compressor in the 18-21 m³/min class — e.g. KSCY-310/22 (21 m³/min @ 2.2 MPa) or KSCY-650/20-700/17T (18-19 m³/min dual-mode).
DTH hammer & bits
3" and 4" DTH hammers cover the Φ90-130 mm range — K3/K30C class for 90-105 mm holes, moving up a size for 130 mm holes. Matching button bits order as a set.
