12 FOCUSED TOOLS
Machining feeds, speeds & time calculators
Translate entered cutting parameters into nominal motion and time estimates.
Choose the right calculation
Choose cutting speeds and feeds from suitable tooling and material guidance. These tools translate quantities rather than selecting safe cutting conditions. Effective diameter, engagement, machine limits and setup time need separate attention.

Spindle Speed Calculator
Convert a selected metric cutting speed and diameter into spindle speed.
Cutting Speed Calculator
Find surface cutting speed from tool diameter and rotational speed.
Milling Feed Rate Calculator
Calculate nominal milling table feed from tooth count, chip load and spindle speed.
Feed Per Tooth Calculator
Recover nominal milling chip load from table feed and rotational speed.
Turning Feed Rate Calculator
Convert a turning feed per revolution into linear travel rate.
Milling Removal Rate Calculator
Estimate nominal metal removal rate for a milling pass.
Machining Time Calculator
Estimate feed-motion time for a machining pass.
Tap Drill Estimate Calculator
Estimate a cutting-tap pilot diameter from a metric diameter and pitch.
Drill Point Length Calculator
Find axial point length for an ideal drill tip.
Turning Diameter Reduction Time Calculator
Estimate repeated turning-pass feed time from travel, feed and speed.
Drilling Material Removal Rate Calculator
Find nominal drilling removal rate from hole diameter and feed.
Machining Cost Calculator
Combine estimated machining time with an hourly rate and extra costs.
Does the spindle-speed calculation recommend a cutting speed?
No. You supply the cutting speed. The tool converts it and a diameter into revolutions per minute.
