metric tap drill rule of thumb calculator online
Use metric tap drill rule of thumb online for major diameter mm, pitch mm. Cut-tap approximation; confirm material and thread-standard guidance before use. Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.
How to use it
Enter major diameter mm. Set pitch mm. Select Calculate and check the labeled output. Copy or download the JSON result.
Options and example settings
Calculation method
approximate_drill_mm = positive(major_diameter_mm-pitch_mm) (^ means exponentiation; trig functions ending in d use degrees).

}Choose the right tool
Use cutting data suitable for the actual tool and material. Effective diameter, engagement and chip thickness affect the applicable formulas. Cycle estimates do not generate machine-ready instructions or validate safe operation.
Limitations and common mistakes
- Cut-tap approximation; confirm material and thread-standard guidance before use. Ideal machining arithmetic. Supplied cutting data are illustrative, and tool limits, workholding, machine protection and real cycle behavior require independent review.
- Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
