Project Ideas

Business

On-Site Desk Cable Grommet Retrofit

Offer a mobile service adding clean cable pass-throughs to desks, conference tables, and media cabinets. The bi-metal teeth handle wood, laminate, and thin metal tops; upsell rubber grommets, brush inserts, and cable management kits.


Door Hardware Installation Service

Provide precise doorknob and deadbolt hole drilling on wood or steel-clad doors using appropriate hole saw sizes and jigs. Package with hardware selection, installation, and strike plate alignment for property managers and homeowners.


Van/RV/Boat Pass-Throughs

Specialize in cutting clean holes for electrical, plumbing, vents, and accessory mounts in vans, RVs, and boats. The tool’s ability to cut wood, metal, and plastic lets you service cabinetry, sheet metal, and composite panels; bundle with grommets, glands, and sealants.


Craft Supply Packs of Plugs

Produce and sell sorted packs of wooden and plastic plugs (the ejected cores) for makers and teachers—perfect for mosaics, game pieces, and inlays. Include size labels and mini templates; sell via Etsy and local craft stores.

Creative

Chickadee Birdhouse Village

Use the hole saw to cut perfect 1-1/4 in entrance holes in cedar or pine birdhouses (ideal for chickadees). The deeper saw body handles 2-by walls in one pass, keeping holes clean and uniform. Create a cluster of small houses on a shared backer for a charming garden feature.


Plug Mosaic Wall Art

Leverage the plug-ejection slot to harvest clean wooden plugs from different species (walnut, maple, cherry) and plastics. Arrange the plugs like pixels to create geometric patterns, gradients, or a custom logo on a plywood panel, then sand and finish for a striking, tactile artwork.


Tea Light and Bud Vase Centerpiece

Bore 1-1/4 in recesses into a 2x6 or 2x8 beam for tea lights or small glass vials as bud vases. The bi-metal edge cuts wood and thin metal tea light cups cleanly; set varying hole depths for visual interest and add a natural oil finish.


Perforated Acoustic Art Panel

Create a grid of partial-depth cuts in plywood or MDF to form a decorative, sound-scattering panel. Vary the hole spacing and depth to blend aesthetics with function, then back the panel with dark fabric for contrast and hang as wall art.
