W-0 Dovetail Keys, brown

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-0 Hoffmann Dovetail Keys are approx. 11/64” wide and 1/8” tall (4.3mm by 3.2mm).


W-0 Dovetail Keys are currently available in three lengths from 3/8” to 1 3/8” (10mm – 35mm) – see chart below.

Typical applications for W-0 Dovetail Keys include very small decorative moulding frames for wall paneling and interior and exterior doors, glass stops, small picture frame molding, delicate and thin shadow-box moldings and window mullions.
W-0 Dovetail Keys are preferred for very small or thin stock lacking enough material to use a W-1 Dovetail Key.
