| Drilling application | Suitability for mineral exploration, geotechnical investigation, or another specified core-drilling task. | A written configuration proposal based on the project’s geology, access conditions, and target hole design. | Confirm that the proposed rig and tooling match the intended work; a rig’s suitability depends on the complete setup, not its product category alone. |
| Depth and capacity claims | Rated drilling depth, rod and core-barrel configuration, and the conditions behind any quoted capacity. | A model-specific technical datasheet and a clear explanation of the stated drilling configuration. | Do not compare depth figures in isolation: achievable depth varies with ground conditions, hole diameter, tooling, and rig configuration. |
| Core recovery system | Compatibility with the required core-barrel system, including wireline options where appropriate. | Tooling specifications, compatible component details, and operating instructions for the proposed system. | Check that the full tooling package is compatible with the rig and the intended drilling method. |
| Power and site requirements | Power source, required utilities, operating footprint, and transport or setup constraints. | Utility requirements, installation instructions, operating and transport details, and a proposed site layout if needed. | Verify that the equipment can be supplied, transported, and operated under the conditions at the project site. |
| Safety and documentation | Safety provisions, operating procedures, maintenance instructions, and documentation for the destination market. | Manuals, applicable conformity documents, and a list of included safety features for the exact model and configuration. | Check that documents match the supplied equipment and the regulations applicable to the destination and intended use. |
| Manufacturing and quality control | Production controls, inspection procedures, component traceability, and configuration consistency. | Quality-system documentation, inspection records or plans, and a factory or production-process review where practical. | Treat management-system certification as supporting evidence, not a substitute for verifying the specific product’s performance and build quality. |
| Parts and after-sales support | Spare-parts availability, troubleshooting support, warranty terms, and service coverage for the destination. | Written warranty conditions, recommended spare-parts list, support contact process, and stated service arrangements. | Compare the clarity and practicality of the support commitment, including response process and parts delivery arrangements. |
| Relevant project experience | Experience with comparable drilling applications, operating conditions, and equipment configurations. | Customer references, project examples, or installation records that can be independently checked where possible. | Give more weight to verifiable experience relevant to your project than to broad, unsupported claims. |
| Total cost and delivery | Equipment scope, tooling, packing, shipping terms, commissioning, training, and ongoing operating costs. | An itemized quotation with delivery schedule, included and excluded items, payment terms, and applicable warranty coverage. | Compare like-for-like quotations; a lower equipment price may exclude tooling, support, or other project costs. |
