Use this route when the task is preparing or checking a gun-drilling setup. The output is a traceable set of inputs and observations, rather than a family-wide parameter recipe.

Identify the tool and supplied material

Read drill construction and geometry to separate solid-carbide, brazed and insert arrangements. Then use materials and catalogue scope to keep grade, condition, tool series and diameter band together.

Retain the exact source entry and applicable operating instructions with the setup. A missing material condition or catalogue revision remains a question to resolve.

Convert values without changing their meaning

Speeds and feeds includes a source-scoped catalogue example and distinguishes feed per revolution from linear feed. Use the conversion calculator for the arithmetic, with explicit metric or inch inputs.

For a cutting-demand estimate, power and torque explains the model and its limits. The result does not size the complete machine or its fluid system.

Establish entry and delivery

Compare the pilot-hole and bushing arrangements. Read coolant supply and return to distinguish the relevant circuit and measurement points.

Keep the tool-specific entry sequence, fluid requirements and approved setup record together. Calculation correctness cannot establish these operating conditions.

Retain the trial and inspection

Record the actual settings, observed chips and inspected bore results. If the trial reveals a fault, move to the fault-investigation route; if the unresolved question is acceptance, use the bore-quality route.
