Recommended packages
Air compressor match
Integrated rig — the screw air compressor is built into the machine, so no separate compressor unit is needed. Only confirm the onboard compressor rating (pressure and flow) matches your hammer size.
DTH hammer & bits
Match the DTH hammer class to your hole diameter: K3/K30C for 90-105 mm, K5/K50 for 135-165 mm — see the DTH hammer series page for the full ladder.
