Work out tool life instantly with clear inputs, formula shown and shareable results.
Taylor's tool life equation V x T^n = C says that cutting speed and tool life trade off along a power law. Because n is small, typically 0.1 to 0.3, life is extremely sensitive to speed: with n = 0.25 a 20 percent speed increase roughly halves tool life.
Taylor tool life
V x T^n = C, so T = (C / V)^(1/n)
V x T^n = C, so T = (C / V)^(1/n). Taylor's tool life equation V x T^n = C says that cutting speed and tool life trade off along a power law.
From cutting trials on the specific tool, material and coolant combination. Published values are starting points only; the constants shift with every change in the setup.
This calculator takes 3 inputs: Cutting speed, Taylor exponent n, Taylor constant C. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
