Choose with confidence.
Start with the application, target depth, hole diameter and ground conditions. Then review the rig, drilling method and supporting equipment together.
Share the application, ground conditions, target depth, hole diameter and project country. Include a preferred drilling method or model if you have one.
Share the rig configuration and drilling method so the required pressure, air flow, hammer, bits and drill rods can be reviewed together. Confirm compatibility against the selected equipment specifications.
Send your proposed configuration and site requirements. Ask our team to confirm the available options and their technical suitability for the project.
Provide the original model, equipment identification, the affected component and a description of the issue. Clear photographs and the relevant operating conditions help the team review your request.
Share the destination or delivery port, equipment configuration and quantity. Packing, shipment arrangements and delivery schedules should be confirmed for the specific quotation.
