A vee groove is a V-shaped channel cut into wood or panels to create decorative lines, spacing, or controlled joints.

A vee groove (often written as V-groove) is a V-shaped channel milled into the surface or edge of wood, plywood, MDF, or panel products. It is commonly used to create decorative shadow lines, simulate board separation, or allow panels to fold or align cleanly. Vee grooves are widely used in finish carpentry, cabinetry, and architectural millwork.

In construction applications, vee grooves are often found in wall paneling, ceilings, doors, and soffits. They help define individual boards or panels without requiring separate pieces, reducing material use and installation time. Vee grooves may also be used to control cracking or expansion by providing a deliberate relief point in the material.

From a fabrication and installation standpoint, vee grooves are typically cut using routers, shaper cutters, CNC machines, or specialized milling equipment. Groove depth, angle, and spacing vary based on design intent and material thickness. Proper finishing of vee grooves enhances visual contrast and contributes to a clean, professional appearance in both residential and commercial interiors.

Vee grooves are often used in modern panel systems to mimic the look of traditional tongue-and-groove boards—without the added labor or material cost.
