The most common sign-making bits are V-groove bits for incised lettering, point-cutting bits for fine engraving lines, plunge ogee bits for decorative incised profiles, and radius grooving bits for rounded channels. The 8-piece Sign Making Router Bit Set includes the most useful profiles in one package.

A 90-degree V-groove bit is the most versatile for block lettering and geometric designs—the wide angle creates a clean, clearly visible channel. Narrower angles (60 or 45 degrees) produce deeper, more dramatic grooves suited to fine detail work.

Freehand lettering with a router requires significant practice and is difficult to keep consistent. Using letter templates with a guide bushing or a bearing-equipped V-groove bit with bearing produces far more consistent results for most woodworkers.

A V-groove bit cuts a simple V-profile and is guided freehand or with a straight edge. A lettering bit is engineered specifically for following letter templates and may have a smaller tip radius to reproduce fine letter details accurately.

Both 1/4" and 1/2" shank options are available. Use 1/2" shank bits when your router accepts them—the larger shank reduces vibration for cleaner lines in detail carving. For compact trim routers used with sign templates, 1/4" shank bits are appropriate.

Raised lettering is typically created by routing away the background around raised letter forms, using a straight or spiral bit with a template. Flush-trim and pattern bits from our flush-trim collection can also be used for this technique.

Clear pine, basswood, cedar, and redwood carve cleanly with V-groove bits and are popular for outdoor signs. Cherry, walnut, and maple produce sharp, crisp letter edges for indoor or display signs. Avoid highly figured grain where tear-out can obscure letter details.

Many V-groove and point-cutting bits can be used in CNC routers with compatible collets. For dedicated CNC sign work, browse our CNC collection for bits and machines optimized for machine routing.
