Find the position of a hole relative to other two

This tool helps you accurately determine the X and Y coordinates of Hole C relative to Hole A based on measured distances and hole diameters. Whether you’re working in manufacturing, machining, or inspection, this calculator simplifies geometric positioning for precise outputs of horizontal (X) and vertical (Y) position of the third hole to the first hole.

Please note: This tool requires highly precise measurements. It is recommended for use only when no other reliable method is available to determine the relative hole location — for example, when working with parts that have jagged, radial, or tapered edges.
