Predrilled Craft/Birdhouse Kits
Produce birdhouse and kids’ woodworking kits with precise 1/16 in pilot holes to prevent splitting and simplify assembly. Batch drill components in pine or MDF, label parts, and sell as ready-to-build kits at markets and online with customization options.
Cabinet Hardware Pilot-Hole Service
Offer a mobile or in-shop service to mark and predrill 1/16 in pilot holes for knobs, pulls, hinges, and trim. The split point starts on finished wood and laminates without a center punch, speeding up clean, accurate installs billed per door/drawer or by the hour.
Skyline Night Lamps
Create and sell personalized lamps by drilling city skylines or custom patterns through thin wood or metal panels and backlighting them. The speed-helix flute helps maintain pace in aluminum and hardwoods, allowing efficient small-batch production for Etsy and craft fairs.
Upcycled Metal Jewelry
Turn washers, flatware, and stamped metal blanks into pendants, earrings, and charms by drilling 1/16 in holes for jump rings. Offer custom sets and gift packaging; the black oxide bits handle copper, brass, and aluminum reliably for consistent results.
Electronics Enclosure Modding
Provide precision drilling for small plastics and aluminum project boxes: ventilation grids, LED indicator holes, cable tie points, and pilot holes for fasteners. Market to hobbyists, IoT startups, and makerspaces with per-unit pricing and quick turnaround.
Creative
Constellation Light Box
Lay out star maps on thin plywood or sheet metal and drill 1/16 in holes for each star; backlight with LEDs to create glowing constellations. The split point keeps the bit from skating on smooth metal, and the speed-helix helps clear chips in wood and acrylic for crisp points of light.
Upcycled Wind Chimes
Drill tiny hanging holes in old keys, spoons, and copper tubing to string them into melodic wind chimes. The black oxide finish holds up well on metals, and the split point starts on contact without a center punch on curved surfaces like spoons.
Scale Model Detailing
Add micro rigging points, portholes, and rivet patterns to balsa, styrene, and brass on model ships and planes. The jobber-length bit is easy to control by hand or in a pin vise, and the split point reduces walking on brass and aluminum parts.
Perforated Lantern
Drill repeating dot patterns in thin aluminum or steel sheet, roll and seam into a cylinder, and place an LED tea light inside. 1/16 in holes create delicate light projections while the speed-helix flute prevents heat buildup during long pattern runs.
Acrylic Charms and Bookmarks
Cut acrylic strips or small wood blanks and drill clean 1/16 in holes for jump rings or tassels. The bit’s geometry evacuates chips efficiently in plastics and hardwoods, producing smooth, chip-free edges ready for polishing.
