Equally Spaced Holes Calculators
Overview:
Equally Space Holes Calculators provide hole coordinates for equally spaced holes where the pitch circle diameter is known. It is a simple, smart tool used by people who build things—like machinists, engineers, and DIY enthusiasts—to figure out exactly where to drill or punch a number of holes around a circle such as during the production of a flange.
Calculator for 3 Equally Space Holes
Instructions:
- Enter diameter of pitch circle in available calculator field in any unit of your choosing for example millimeters. refer to diagram for value definition.
- Choose how many decimal places you wish answer to round to, the default value is one.
- Press solve button to find remaining unknown values in same unit used for diameter.
- To perform a new calculation or you wish to clear current values use the reset button
to clear values and start again. - The formula / multipliers used to calculate each missing value are visible as placeholders in the missing value fields prior to a calculation being performed.
If diameter (D) of pitch circle is
value (A):
value (B):
value (C):
requirements not met -
please add value for diameter (D).
