Project Ideas
Business
Decorative Vent & Radiator Covers
Produce custom perforated wood covers with consistent 1/4 in hole or slot patterns. Offer design templates, measured installs, and finishes (paint, clear coat) for a premium look.
On-Site Panel Modification Service
A mobile service for contractors/homeowners: add wire pass-throughs, grommet holes, and access ports in cabinetry, closets, and wall panels. The pilot point enables clean plunge cuts without pre-drilling.
Acoustic Treatment Packages
Sell and install slotted/perforated acoustic panels for home studios, offices, and cafes. Use templates and the single-flute bit to produce repeatable patterns; upsell frames and mounting hardware.
Trade Show & Pop-Up Backdrops
Fabricate lightweight perforated panels with branded patterns that accept hooks and signage. Rent or sell modular sets; the bit enables quick production in MDF/ply ≤3/4 in.
Van/RV Upfit Cutout Solutions
Offer precise cutouts in plywood skins and insulation for lights, vents, and cable management. The drill-through pilot speeds entry and reduces tear-out in thin panels during mobile installs.
Creative
Backlit Perforated Wall Art
Lay out a starfield or geometric pattern on thin plywood, use the drill-through pilot point to plunge clean 1/4 in holes, then route shallow wire channels on the back. Add LED strips and a diffuser for a glowing wall piece.
Custom Pegboard Tool Wall
Create bespoke pegboards with non-standard spacing and shapes. The pilot point starts each hole precisely; the single flute evacuates chips in plywood/MDF for crisp 1/4 in perforations.
Acoustic Slot Panels
With a straightedge guide, plunge and route 1/4 in slots through MDF or plywood (≤3/4 in thick). Back the panel with acoustic felt to build stylish noise-dampening wall treatments.
Camper Ceiling Constellations
Perforate thin ply ceiling panels with constellation patterns using the pilot point for accurate starts, then backlight for a starry-night effect in vans or tiny homes.
Foam Board Architectural Models
Cleanly drill windows, doors, and cable channels in XPS or foam insulation boards. The single flute reduces melting and clogging, ideal for quick model-making and mockups.
