What is a jig in woodworking?

A jig in woodworking is specifically a custom-made tool designed to securely hold workpieces in position during various machining operations. This allows for increased precision and efficiency in tasks such as cutting, drilling, or shaping, as the jig often incorporates guides and stops that ensure that each piece is handled consistently and accurately. By stabilizing the workpiece, jigs help woodworkers achieve repeatability and higher quality in their projects.

Other options present concepts related to woodworking but do not accurately define what a jig is. Tools for cutting wood are broader and do not imply the holding and positioning aspect that a jig provides. A finish applied to wood refers to surface treatments for aesthetics or protection, and this is unrelated to the functionality of a jig. Similarly, a type of wood glue pertains to adhesive applications in woodworking, which does not cover the supporting or positioning function inherent to jigs.
