Bolt Circle Calculator

The function of the bolt circle calculator enables the machinist to calculate X and Y coordinates for points arranged equally spaced in a circle, then copy those coordinates to the clipboard ready to send to your printer or paste into a CNC program.
Optionally, you can insert a line of text (such as a sub routine call) between each coordinate line.
For manual machine users, the coordinates can be printed on your computer's printer.

As with all functions of the Machinist's Calculator, linear values can be converted between inch and millimeters, including the x,y coordinates in the answer.
The starting angle must be entered as decimal degrees, but the bolt circle calculator has access to our Angle Converter, which will enable the user to convert between degrees.decimal and degree-minute-second.

The pitch circle calculator can also be found in the Adroid OS and PDA versions of the Machinist's Calculator.
