What is a plunge cut?

A plunge cut is a type of cutting technique used in woodworking or metalworking, where the tool is plunged vertically into the surface to create a cut. This is different from traditional cutting, where the tool is moved along a horizontal plane to create the cut. Plunge cuts are used to create precise holes or slots in materials, and can be performed with a variety of cutting tools, including saws, routers, and drills. Plunge cuts require a steady hand and careful control of the tool, as mistakes can result in damage to the material or injury to the user. Some tools may have specialized guides or features to help facilitate accurate and safe plunge cuts.
