Project Ideas
Business
On-site drilling and tapping service
Offer mobile precision hole-making for metal: enlarging to 33/64 in for tight 1/2 in bolt clearance and pre-drilling for 9/16-18 taps in structural steel, trailers, gates, and equipment. Market to general contractors, fabricators, and property managers who need clean, aligned holes without shop downtime.
No-weld metal furniture kits
Design and sell bolt-together steel furniture (shelves, benches, racks). Pre-drill 33/64 in holes so customers assemble with common 1/2 in hardware. The deeper-reach bit helps you produce straight, through-tubing holes for professional alignment using only a 1/2 in drill press.
Fixture plates and brackets with 9/16-18
Manufacture and sell steel fixture plates, angle brackets, and positioning blocks tapped 9/16-18. Use the 33/64 in drill as the tap drill for fast production. Target makers, welders, and machine shops needing robust fixturing without CNC lead times.
Drilling jig and hardware bundle
Create a kit: this reduced-shank bit, a simple tube-drilling jig, layout template, cutting fluid, and 1/2 in hardware. Sell to DIYers who want accurately aligned through-holes in square or round tubing without a mill. Upsell replacement bits and consumables.
Workshops and content monetization
Run classes on drilling/tapping steel and publish short-form videos showing techniques for deep, straight holes using a 1/2 in drill press. Monetize via course fees, sponsorships, affiliate links to tools/consumables, and downloadable project plans that leverage 33/64 in and 9/16-18 hardware.

Bolt-together industrial shelf/bench
Build modular steel shelves or a workbench using 1/2 in bolts. Drill 33/64 in close-clearance holes in angle iron and square tube so parts align cleanly. The 4 in working length makes it easy to drill through both walls of tubing in one setup for perfectly coaxial pass-through holes.
Welding table with 9/16-18 threaded grid
Lay out a grid and pre-drill with the 33/64 in bit as the tap drill for 9/16-18 threads. Tap the holes to accept clamps, stops, and jigs. The reduced shank lets you use a standard 1/2 in drill press, and the black oxide finish helps with chip evacuation in thicker plate.
Hitch-mounted accessory rack
Fabricate a receiver-mounted rack for coolers, tools, or bikes. Use 33/64 in holes for tight 1/2 in bolt connections and tap 9/16-18 where you want adjustable anti-rattle screws or clamp knobs. The extended bit length helps drill through boxed sections neatly.
Industrial floor lamp with hidden wiring
Make a steel-tube floor lamp or coat rack. Drill clean access and pass-through holes in tube and plate for wiring runs and fasteners. The long working length makes routing holes in deeper sections practical while keeping holes aligned.
Smoker/grill bolt-on accessory system
Add bolt-on shelves, hooks, and thermometer mounts to a smoker or grill. Use 33/64 in close-clearance holes for 1/2 in hardware, and tap select points to 9/16-18 for adjustable feet or clamp-on accessories.
