The Hoffmann Dovetail Joining System is a versatile solution widely used across woodworking, furniture manufacturing, window and door production, architectural millwork, store fixtures, custom and production picture framing, and prefab housing industries worldwide. Designed to accommodate a growing range of joining applications, the system offers five different Hoffmann Dovetail Key sizes, each with corresponding Dovetail Router Bits: W-0, W-1, W-2, W-3, and W-4. The ?W? designation indicates the cross-section of the Keys (resembling a "bowtie"), and each size is available in various lengths to suit diverse project requirements. This flexibility makes the Hoffmann system a trusted choice for precision and efficiency in professional woodworking and manufacturing.

Hoffmann Dovetail Keys, size W-3, are a popular size for a wide range of woodworking applications including miter joints, butt joints, compound miter joints and end-to-end joints. The W-3 Dovetail Keys are larger in both width and height compared to W-2 Keys, and are therefore exerting more clamping pressure and holding strength in all types of miter and butt joints. Typical uses include cabinet and furniture frames, straight and curved handrail joints, heavy column bases, bar and chair rails, wooden ceiling systems, outdoor furniture as well as institutional and commercial mitered cabinet doors. In addition, heavy wood components with large cross section, such as casket lids and casket side panels, sauna and steam-room components, post and beam construction etc. often require the use of W-3 Keys.
