Project Ideas
Business
Species-Specific Birdhouse Kits and Workshops
Produce and sell CNC-cut or hand-cut birdhouse kits with precisely sized entry holes (1-1/8 to 1-3/16 in) and optional sheet-metal predator guards. Offer weekend workshops where participants assemble and finish on-site. Market locally and online; the arbor’s HSS durability handles reclaimed, nail-embedded stock for a sustainable story.
Custom Enclosure and Panel Modding
Provide a service adding clean pass-throughs for panel-mount connectors, switches, and cable glands in metal/plastic enclosures (9/16–1-3/16 in). The 135° split-point pilot prevents walking on sheet metal for professional results, and the hex shank speeds mobile jobs with an impact driver. Target makers, synth/FX builders, robotics teams, and small OEMs.
On-Site Pass-Through Drilling for Trades
Partner with electricians, low-voltage installers, and plumbers to drill cabinet, rack, and light-gauge metal pass-throughs sized for EMT, PEX, and bushings (e.g., 1-1/8 in for 3/4 in EMT). The adjustable/replacable pilot bit minimizes tear-out in finished cabinetry and speeds bit changes mid-job. Offer per-hole or hourly pricing with rapid response.
Batch-Made Candle Blocks and Organizers
Manufacture small-batch taper candle blocks and pen/brush organizers using hardwood offcuts. The arbor’s range covers popular hole sizes, enabling fast, repeatable production runs. Sell via Etsy, craft fairs, and wholesale to boutiques; brand with a stamp and offer custom engraving add-ons.
Van/RV Upfit Hole Prep
Specialize in drilling clean holes in thin sheet metal and interior panels for cable glands, water lines, and ventilation grommets (3/4–1-3/16 in). The split-point pilot bit bites quickly into metal skins without wandering, and the HSS build withstands mixed materials. Partner with mobile upfitters and charge per cut or bundled package pricing.

Species-Specific Birdhouse
Build birdhouses from reclaimed fencing or barn wood and cut precise entry holes sized to the species (1-1/8 in for chickadees, up to 1-3/16 in for wrens). The arbor’s hardened HSS and split-point pilot bit handle nail-embedded wood and thin sheet-metal predator guards cleanly. Adjust the pilot bit shorter to reduce blowout on the exit side, and pop the core free for a tidy edge.
Taper Candle Block Centerpiece
Create minimalist hardwood blocks with 7/8 in to 1 in holes for taper candles or ferrules. The adjustable pilot lets you set shallow depth for blind holes, or remove/shorten it to avoid poking through on thinner stock. Batch multiple holes evenly in maple or walnut for a sleek table centerpiece.
Test Tube Spice Rack
Make a countertop spice rack that holds 25 mm (≈1 in) glass tubes. Use the hole saw to drill clean, repeatable holes in hardwood slats and add a thin sheet-metal label strip; the 135° split-point pilot prevents skating on metal. The hex shank works with an impact driver for quick batch production.
Electronics Cable Pass-Through Panel
Build a small MDF or acrylic panel with 3/4 in to 1 in holes sized for rubber grommets and cable glands. The split-point pilot starts cleanly in plastic and sheet metal project boxes, while the HSS arbor stays sharp across materials. Use the quick pilot-bit swap to change lengths when switching between thin enclosures and thicker panels.
Pen and Brush Desk Organizer
Glue up a hardwood block and drill a grid of 9/16 in to 1 in holes to fit pens, markers, and paintbrushes. Vary diameters for different tools within the arbor’s range. Adjust the pilot bit to just scribe and guide without breaking through for a cleaner look on shallow recesses.
