Creative
Mini Bluetooth Speaker
Build a compact Bluetooth speaker using 2.5-inch full-range drivers. The 2-9/16 in hole saw makes clean driver cutouts and rear bass ports in plywood or plastic. Use the ejected wooden plugs as stand-off feet or decorative accents. Check driver datasheets (many call for 63–66 mm cutouts) and line the enclosure for better sound.
Grid Wall Art with Inlays
Drill a geometric grid of 2-9/16 in holes in a hardwood panel, then use the cut plugs as contrasting inlays (stain the panel dark, leave the plugs natural, or vice versa). The deeper saw lets you cut through 2x stock to make chunky inlays. Mount over a colored backing or felt for a striking, modern look.
Toy Car Wheels
Cut uniform hardwood discs for sturdy toy car or tractor wheels. Sand edges, drill centered 1/4 in axle holes, and add a small chamfer with sandpaper or a router. The hole saw’s continuous slot simplifies plug ejection for batch production.
Cable-Grommet Charging Station
Make a desktop charging caddy with one or more 65 mm cable grommets. Cut holes in a wooden box lid, drop in 60–65 mm desk grommets, and route USB-C/Lightning cables and a power strip inside. Add a wireless charger pad and felt lining for a clean, organizer-style look.
Perforated Acoustic Panel
Create a decorative acoustic panel by drilling a pattern of 2-9/16 in perforations in plywood or MDF and backing it with acoustic felt/foam. The large holes reduce weight and improve sound absorption while the pattern doubles as wall art.
