Basic calculation first. Advanced check second.
Run the simple relationship first, then use the advanced version when the operation needs more variables or machine constraints. The calculators are intentionally stacked, not side by side.
Basic Cutting Speed Calculator
Calculate cutting speed from RPM and diameter.
Cutting Speed Basic
Enter the values you know. The result is calculated in your browser.
Calculation only. Verify toolmaker data, material grade, engagement, machine limits, workholding and actual cutting conditions before production.
Advanced Cutting Speed Calculator
Use the fuller calculator when the dedicated variables and machine constraints matter.

About this calculation
Calculate cutting speed from RPM and diameter. The formulas are transparent and the result should be checked against the actual tool and material data.
