Cut Open Bolt Hole

This tool creates the profile for a bolt hole that is rounded on both the entrance and exit sides (e.g., a counterbored hole with fillets).

Detailed Geometry

It allows you to specify not just the width and depth of the hole, but also the fillet radius for the opening, creating a more realistic or specific mechanical detail.

Input

Requires a center point, direction, hole diameter (width), hole depth, and the fillet radius for the entrance.
