Machinist Speeds & Feeds

Avoid burning a carbide tool on the first pass. Get starting RPM and feed in seconds instead of hunting charts at the machine.

Avoid burning a carbide tool on the first pass. Get starting RPM and feed in seconds instead of hunting charts at the machine.

Machinist Speeds & Feeds helps machinists, CNC operators, and machining students turn diameter, material, chip load, and cutting speed into shop-floor starting values without charts, spreadsheets, or a network connection.

Use the free core to:

• turn diameter, cutting speed, chip load, and feed per revolution into starting RPM and feed
• check target RPM, applied RPM, achieved surface speed, and clamp-limited results side by side
• switch between imperial and metric inputs without leaving the setup
• keep starter materials ready for 6061 aluminum, 1018 mild steel, and 304 stainless

Unlock Pro Setup Cards to:

• open the full starter material library for aluminum, steels, stainless, brass, cast iron, tool steel, titanium, plastics, and more
• load quick presets instead of rebuilding the same setup at the machine
• save, pin, reload, and share reusable setup cards for repeat jobs
• hand off a clean setup summary with material, tool, diameter, flute count, clamp state, and result values

Why machinists keep it:

• fewer handbook lookups on the shop floor
• fewer bad first passes when a starting point is needed fast
• faster setup-card handoff for repeat work
• offline, no account, no ads, no tracking

Important: Results are starting references only. Final parameters must still be adjusted by the machinist for toolmaker guidance, machine limits, workholding, coolant strategy, and shop rules before cutting.
