Old-Home Trim Salvage & Reuse
Offer on-site removal and refit of vintage casing, baseboards, and shiplap. Use controlled plunge/flush cuts to free pieces and slice through hidden nails without splintering, thanks to the bi-metal teeth and vibration damping. Monetize by reselling cleaned trim or reinstalling it after repairs.
Retrofit Niche and Cutout Specialist
Provide clean interior cutouts for recessed shelves, medicine cabinets, speaker grilles, and low-voltage boxes. Curved-Tec enables precise starts without overcutting corners; StarlockMax quick changes keep throughput high. Price per opening plus finishing upsells (beads, patching, paint).
Accent Wall Installer (Reclaimed/Pallet)
Install wood accent walls efficiently. The blade’s BIM teeth handle surprise nails, letting you scribe, notch, and cut boards around outlets, trims, and vents on the fly. Offer material sourcing, layout design, and one-day installs for premium margins.
Mobile Van/Closet Upfit Cuts
Customize van interiors and closet systems: plunge vents, cable pass-throughs, and accessory mounts in plywood, laminate, and PVC. The 4 in segment blade speeds straight, repeatable cuts in tight spaces, while the StarlockMax mount delivers torque for dense materials.
A/V and Smart Home Cutout Partner
Partner with integrators to cut precise openings in drywall, cabinets, and MDF for in-walls, touch panels, and cable plates. Controlled plunge cuts reduce blowout and cleanup time. Bill per location with add-ons for backboxes and paint-grade finishing.
Creative
Reclaimed Nail-Kissed Mosaic Wall Art
Slice and shape thin tiles from reclaimed lumber (even with embedded brads) using the bi-metal teeth. Use controlled Curved-Tec plunge cuts to create facets and arcs, then puzzle them into a mosaic panel. The wide 4 in segment edge lets you true edges quickly, while side-set teeth keep cuts fast and clean.
Geometric Lattice Room Divider
Layout a hex or triangle grid on 1/2 in plywood and plunge the interior starts with the curved edge—no pilot holes needed. Connect lines with the extra-wide segment blade for straight, repeatable cuts. The vibration-reduction slots help keep kerfs crisp for a modern, airy divider.
Drywall Recessed Display Niches
Mark stud bays and use controlled plunge cuts to open drywall precisely for niches, shelves, or medicine cabinets. The 1 in immersion depth handles single-layer drywall cleanly. The segment form hugs corners, reducing overcuts for a pro-looking recess ready for trim.
PVC Lantern/Light Sculpture
Cut repeating windows and curves into PVC pipe or sheet to create a patterned lantern. The bi-metal teeth chew through PVC cleanly, and the curved plunge lets you start inside shapes. Finish with LED strip lighting for a durable, weather-resistant light feature.
Cable-Channel Picture Ledge
Build a wall shelf with hidden wire management by plunge-cutting a rear channel and side exits in the stock. The 4 in segment blade makes long, straight recesses easy; if you hit an old nail, the BIM teeth keep you moving. Add a snap-on cover strip for a clean look.
