COUNTERBORE Meaning and
Definition
-
Counterbore is a machining term referring to a specific type of hole made in a workpiece. It is a cylindrical recess that is created at the surface of the material, aiming to accommodate the head of a fastener, nut, or bolt. This recess allows the fastener to be recessed below the surface, resulting in a flush or slightly below the surface finish.
To create a counterbore, a counterboring tool is used, typically in the form of a drill bit or end mill. The tool is designed with a pilot at its tip, which guides the cutting edge to maintain accuracy and alignment. The pilot is followed by a larger diameter section, which cuts the recess to the desired depth. The bottom of the counterbore is usually flat, providing a stable surface for the fastener head to rest against.
Counterboring is essential in various applications, particularly when a smooth and flush appearance is desired, or when it is necessary to prevent interference between protruding fasteners and adjacent components. Common examples include countersinking screws in woodworking projects, creating counterbores for socket head cap screws, or preparing holes for dowel pins.
Overall, a counterbore is a mechanical feature or recessed hole in a material that allows the accommodation of fastener heads or other components, resulting in a flush or slightly below the surface finish.

Etymology of COUNTERBORE
The word "counterbore" is derived from the combination of two separate words: "counter" and "bore".
The term "counter" in this context comes from the Old French word "contre", meaning "against" or "opposite". It later made its way into English through Middle English. In the case of "counterbore", this prefix refers to the action of going against or opposite the original bore.
The word "bore" comes from the Old English word "bor", which means "hole", "pit", or "cavity". It is also related to the Old High German word "borōn", meaning "to bore" or "to drill".
Therefore, "counterbore" can be seen as a compound word combining "counter" (meaning "against" or "opposite") and "bore" (meaning "hole").
