Taylor Tool Life Calculator

Calculate tool life using Taylor's tool life equation. Compare tool lives at different cutting speeds.

Surface cutting speed.
m/min
Tool material exponent. HSS: 0.1-0.15, Carbide: 0.2-0.3, Ceramic: 0.4-0.6.
Speed for 1-minute tool life. Higher = better tool. Carbide on steel: 200-400.
m/min
Second cutting speed for comparison.
