Taper Calculator

Calculate taper angle, ratio, and dimensions for machining and engineering

Taper Formulas and Standards

Taper Angle (θ) = arctan((D - d)/(2L))

This fundamental formula helps calculate the angle of taper for machining and engineering applications.

Common Taper Types:

  • Morse Taper: Standardized taper used in drill bits and machine tool holders
  • NPT Taper: National Pipe Thread taper used in piping systems
  • Metric Taper: Taper standards used in metric system countries
  • Ball Joint Taper: Specialized tapers used in automotive and mechanical joints

Key Applications:

Machining

Precision calculation of taper angles for lathe operations and tool holding

Piping Systems
