A full self-drilling anchor system includes hollow core bar, extension coupler, drill bits, nuts, plates and drilling equipment.
Typical drilling machines used mostly are surface crawlers like Atlas Copco ROC or Geotechnical Drill Rigs equipped with Drifter or a Rotary/Impact Mechanism like Atlas Copco Mustang and Atlas Copco Boomers.

If smaller sizes rock bolts like R25 and Titan 30/11 Self-drilling Anchor are installed, a handheld drill rig (a rotary percussion drill device) can be used. This is common in narrow headroom works.
This is the drilling process for SDA system. Meanwhile, the grout is ongoing to provide bonding strength between the bar and the soil/rock. A mixing and a pump are required. For example, Gamma GPM Water pump, MAI grout pump M400NT is a famous one pass mixing and pumping unit.
