borrsänk

A borrsänk is a specialized tool used primarily in woodworking and carpentry for drilling and enlarging holes in wood and other soft materials. The term "borrsänk" originates from Swedish, where "borr" means drill and "sänk" refers to a countersink or a tool that enlarges or countersinks a hole.

Typically, a borrsänk is a hand-held or machine-mounted device designed with a conical, flanged, or stepped cutting edge. Its primary function is to create a smooth, finished entry or exit point for screws or bolts by widening the diameter of an existing hole or creating a countersink. This ensures that screw heads sit flush with or below the surface of the material, providing both aesthetic appeal and functional benefits such as reducing the risk of material splitting.

Borrsänkar come in various sizes and shapes to accommodate different hole diameters and depths. They are often used in conjunction with standard drill bits and are particularly valuable when working with hardwoods, softwoods, and composite materials.

The tool is commonly employed in furniture making, cabinetry, and other woodworking projects where precise and clean holes are critical. Its design allows for easy manual operation, though power-driven versions also exist for increased efficiency in professional settings.

Overall, the borrsänk is an essential tool for carpenters and woodworkers seeking to achieve clean, professional finishes in their projects.
