To buy a water-well drill bit, turn the selected drilling method into a clear product specification. Use the water-well selection guide if the tool route is still undecided. This checklist helps contractors, distributors and OEM buyers request comparable configurations and quotations.
Identify the item you are ordering
Start with the product reference or drawing revision. State whether the item is a complete bit, a body, a cutting component or an assembly with additional parts. Separate different sizes and connections into individual line items.
| Order field | What to provide |
|---|---|
| Drilling task and reference | Full-hole drilling, sampling or enlargement; selected product or drawing reference. |
| Dimensions | Required diameter and relevant length or gauge; core and barrel dimensions if sampling. |
| Connection | Thread and seating drawing or exact DTH hammer/shank reference. |
| Ground and equipment | Known formation interval, rig model and flushing arrangement. |
| Quantity and scope | Quantity by configuration; complete tools versus bodies or components. |
| Acceptance | Agreed dimensional checks, applicable material or inspection documents and marking. |
| Commercial comparison | Quotation currency, included supply, packaging, delivery scope and validity. |
Add the fields for your selected tool
For tricone roller bits, identify the tooth or insert configuration, circulation and bearing specification. For DTH bits, identify the hammer and shank as well as the head diameter. For a spiral PDC configuration, specify the cutting face, gauge and thread. These are different specification paths rather than one universal checklist of interchangeable parts.
Compare equivalent quotations
Check whether each offer covers the same configuration, quantity and supplied condition. A bare-body quotation is not directly comparable with an assembled bit. Separate transport and other included items consistently. The PDC pricing guide explains the cost inputs and the difference between purchase price and observed cost per metre.
Define a trial or repeat order
For a trial, record what the comparison is meant to answer and which tool, interval and operating information will be retained. For a repeat order, include the previous drawing revision or part reference and identify any required change. Agree the order-specific sample, inspection and delivery arrangements in the quotation.
Prepare an OEM or distributor specification
Add drawings or sample photographs, material and tolerance requirements, cutter or holder details and the assembly state. Identify marking and packaging requirements where relevant. Use Custom & OEM for a drawing-based requirement; the product name alone does not define the manufacturing and acceptance scope.
Before placing the order
Check the selected configuration, mating connection, quantities, included components, acceptance criteria and commercial terms against the final quotation. Keep the accepted drawing and order reference so the delivered item and subsequent run record can be traced to the same specification.
