Counterbore

Counterbore documents the stepped recess machined to seat a fastener head or feature flush with the surface. The model records both the primary through-hole information and the enlarged cylindrical pocket, including diameters, depths, tolerances, and any angular specifications. It also tracks companion features such as the bolt type or associated threads to help CAM and inspection software determine tooling and gauges. Because counterbores often include sequencing instructions, the object preserves notes and surface finish requirements as well. When you consume this model you can automatically verify that the pocket will accommodate the specified hardware, estimate material removal, or flag conflicts with minimum wall thickness guidelines.
