FREE TOOL

Free Speeds & Feeds Calculator

Calculate spindle RPM and feed rate for milling, turning, and drilling. Built-in SFM/SMM tables for Aluminum, Mild Steel, Alloy Steel, Stainless 304, Cast Iron, Brass, and Titanium — HSS and Carbide. Override any value and export as CSV. No login required.

HOW IT WORKS

  1. Select material and tool material — the calculator looks up the recommended cutting speed (SFM or SMM) automatically.
  2. Choose operation — Milling, Turning, or Drilling. Enter tool diameter and number of flutes.
  3. Override SFM/SMM and chip load (optional) — the recommended values auto-fill; change them for your specific tooling or finish requirements.
  4. Read RPM and feed rate — results update instantly in inch (IPM) or metric (mm/min). Export CSV for your setup sheet.
