Creative

Sliding-Lid Keepsake Box

Build a compact box from 3/4 in stock and plow a 3/8 in wide stopped groove near the top of the sides for a sliding lid. Use the bit to rabbet the bottom panel into the box and to create a shallow finger-pull recess on the lid. The 25/32 in cutting length comfortably handles grooves and rabbets in 3/4 in material.


Modular Desk Organizer Grid

Create a desktop organizer from a flat base with a grid of 3/8 in dados that accept removable dividers. Space the dados at regular intervals (for example, every 2 in) to let you reconfigure compartments for pens, sticky notes, and cables. The straight bit makes clean, square-bottom grooves that fit 3/8 in plywood dividers perfectly.


Epoxy Inlay Wall Art

Route 3/8 in wide channels in a hardwood panel following a paper template of a city skyline or geometric pattern. Fill the recesses with tinted epoxy or contrasting wood strips, then sand flush and finish. The carbide-tipped edges leave crisp walls that make the inlay lines look sharp and intentional.


Rabbeted Picture Frame/Shadow Box

Cut precise rabbets on the inner back edges of frame stock to seat glass, artwork, and a backer. Add shallow dados for internal shelves if making a shadow box for collectibles. The controlled depth of cut helps keep passes consistent along long miters.


Finger-Jointed Tea Caddy

Use a simple router table jig to cut 3/8 in finger joints on box corners for a strong, decorative tea caddy. The bit’s width sets finger size, and the straight, square cuts ensure tight, repeatable fits. Finish with a rabbeted bottom and a hinged lid.
