Project Ideas
Business
Office desk cable management retrofits
Offer a service installing 3 in cable grommets and flush wireless chargers in offices and classrooms. Drill clean 2-7/8 in holes on-site in wood, laminate, and thin metal tops. Charge per hole plus hardware; minimal mess thanks to efficient chip removal.
Hydroponic lid production
Produce and sell pre-drilled bucket and tote lids with 2-7/8 in cutouts for 3 in net pots. Cater to home growers and garden shops. The bi-metal saw makes quick, clean work of plastic lids and thin aluminum covers, enabling small-batch and custom spacing.
Branded coaster and ornament shop
Mass-produce 2-7/8 in wooden coasters from reclaimed 2x lumber. The deep cup allows single-pass cuts; the plug-eject slot speeds throughput. Add engraving or UV-printed logos for breweries, cafes, and wedding favors.
Dust collection retrofit service
Install 2-1/2 in PVC ports in hobby woodshops and makerspaces. Your 2-7/8 in holes provide a snug fit for 2.875 in OD pipe and couplers. Upsell blast gates, hoses, and custom manifolds for a turnkey airflow upgrade.
RV/van/boat cup-holder and pass-through installs
Mobile service adding recessed cup holders and cable pass-throughs that commonly specify 2-7/8 to 3 in cutouts. Bi-metal teeth handle plywood, fiberglass backers, and thin aluminum skins, letting you work across platforms from camper vans to small boats.

Hydroponic lids for 3" net pots
Cut 2-7/8 in openings in tote or bucket lids to press-fit standard 3 in net pots (many specify a 2-7/8 in cutout). The bi-metal teeth slice through plastic lids and thin sheet metal covers cleanly, and the 1.75 in cutting depth is more than enough. Build tidy Kratky or DWC rails by spacing multiple holes evenly.
Compact DIY speakers
Build desktop or bookshelf speakers using 3 in full-range drivers that commonly call for a 73 mm (2-7/8 in) cutout. The deeper saw design handles 3/4 in panels easily for driver and port holes. Capture the wooden plugs for badges or feet.
Wooden coasters and ornaments from plugs
Drill into 2x offcuts to pop out 2-7/8 in wooden discs suitable for coasters, ornaments, and game tokens. The large slot speeds plug ejection, and the depth lets you make thick, single-pass coasters. Sand, inlay resin, or woodburn designs for a polished set.
Desk cable grommets and wireless chargers
Add 2-7/8 in holes to desks or nightstands for 3 in cable grommets and many flush-mount Qi chargers (typical 70–76 mm cutouts). Bi-metal construction gives clean edges in hardwood, laminate, and thin metal tops for a factory-finished look.
Dust collection manifold
Cut 2-7/8 in holes in plywood to press-fit 2-1/2 in schedule 40 PVC pipe or couplers (2.875 in OD). Create a wall-mounted manifold or tool hoods to organize shop-vac connections and reduce hose juggling.
