Product Description
The Hoffmann Dovetail Joining System is used in woodworking, furniture manufacturing, window and door production, architectural millwork designs, store fixtures, custom and production picture framing shops, pre-fab housing and much more, in shops and plants around the globe.
To best suit an ever expanding range of joining application, a total of five different Hoffmann Dovetail Keys and corresponding Dovetail Router Bit sizes are offered, designated as W-0, W-1, W-2, W-3 and W-4.
The “W” designations refer to the cross-sections of the Keys (the size of the "bowtie"), and Keys in each size are available in a variety of different lengths.
The cross-section dimensions of W-3 Hoffmann Dovetail Keys are approx. 1/2” wide and 3/8” tall (13mm by 9.5mm).
W-3 Dovetail Keys are available in lengths from 1/2” up to 4” (12.7mm – 100mm) – see chart below.
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.
Special applications, for example mitered doors with heavy glass or mirror panels and floor-to-ceiling type doors for laboratories and schools, are often joined with W-3 Dovetail Keys as well.
