Taylor Tool Life — Uncoated Carbide on Steel
Predicted minutes of tool life from cutting speed via V·Tⁿ = C, preset for uncoated carbide on steel.
With n ≈ 0.25, doubling cutting speed divides carbide life by roughly 16 in steel. The economic sweet spot usually lands at 15–45 minutes of life per edge — long enough to be cheap, short enough to be fast.
Formula
Note: Taylor constants vary widely with grade, coating and coolant — treat presets as order-of-magnitude and calibrate n and C from two timed wear tests on your own setup.

About Taylor Tool Life — Uncoated Carbide on Steel
Taylor Tool Life — Uncoated Carbide on Steel computes the governing relationship V·Tⁿ = C → T = (C/V)^(1/n) live as you type. With n ≈ 0.25, doubling cutting speed divides carbide life by roughly 16 in steel. The economic sweet spot usually lands at 15–45 minutes of life per edge — long enough to be cheap, short enough to be fast. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Taylor Tool Life — Uncoated Carbide on Steel
- 1Enter your values — Cutting speed V, Taylor exponent n, Taylor constant C (sensible defaults are pre-filled).
- 2Read the live results: Predicted tool life, Speed for 30 min life, Speed for 60 min life.
- 3Check the "with your numbers" line to see V·Tⁿ = C → T = (C/V)^(1/n) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Taylor Tool Life — Uncoated Carbide on Steel?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded

Frequently asked questions
What formula does the taylor tool life — uncoated carbide on steel use?+
It evaluates V·Tⁿ = C → T = (C/V)^(1/n), exactly as published. Sources: ISO 3685 — Tool-life testing with single-point turning tools; Kalpakjian & Schmid, Manufacturing Engineering and Technology, 7th ed., ch. 21. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
With n ≈ 0.25, doubling cutting speed divides carbide life by roughly 16 in steel. Taylor constants vary widely with grade, coating and coolant — treat presets as order-of-magnitude and calibrate n and C from two timed wear tests on your own setup.
When is this calculator the right tool for the job?+
Predicted minutes of tool life from cutting speed via V·Tⁿ = C, preset for uncoated carbide on steel. A free cnc machining: speeds, feeds & tool wear tool. The economic sweet spot usually lands at 15–45 minutes of life per edge — long enough to be cheap, short enough to be fast. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
