Business

Electrical Box Cutout Specialist

Offer precision cutouts for outlets, switches, and low-voltage boxes after drywall hanging. The 2-1/8 in blade matches single-gang box width for fast, accurate openings, and the PlungePoint blade enables clean starts without overcutting—ideal for drywall contractors seeking speed and reduced patchwork.


Trim and Jamb Undercutting for Flooring

Provide door jamb and casing undercuts so new flooring slides underneath seamlessly. The oscillating setup makes controlled, flush cuts without removing trim. Bundle with transition installs and baseboard notching for a profitable add-on service to flooring crews.


Selective Deconstruction & Lumber Salvage

Specialize in carefully dismantling built-ins, cabinetry, and reclaimed lumber where nails are present. The carbide-tipped blade handles nail-embedded wood, enabling you to preserve material quality for resale or reuse. Market to renovators and eco-builders needing clean, reusable components.


Targeted Access for Leak/Pest Diagnostics

Partner with plumbers, HVAC techs, and pest control companies to open small, strategic inspection ports. Use controlled plunge cuts to minimize damage and dust, then patch neatly. Offer same-day cut-and-patch packages to streamline trades’ service calls.


Smart Home Retrofit Cutouts

Install smart switches, sensors, and cable pass-throughs in finished spaces. The tool’s precise plunge capability allows tidy openings for single-gang and retrofit boxes, plus tight slots for wire routing. Bundle with device setup for a turnkey homeowner service.

Creative

Recessed Stud-Bay Wall Niche

Create sleek wall niches between studs for books or decor. Use the 3-sided 2-1/8 in drywall blade to plunge and rip along the layout lines, and the PlungePoint blade to start tight, controlled corners. Build a shallow box to fit between studs and slide it into the opening for a clean, built-in look.


In-Wall Charging Nook

Make a tidy, recessed shelf for phones and tablets with a flush outlet. The 2-1/8 in blade matches single-gang box width for perfectly sized electrical openings, while the PlungePoint blade handles precise cable pass-throughs. Finish with a small trim frame for a professional result.


Reclaimed Accent Wall with Metal Inlays

Upcycle pallet or barn wood into an accent wall. Use the carbide-tipped blade to deal with hidden nails and to trim metal inlays. The PlungePoint blade lets you notch boards for LED strip channels, and the general-purpose blade cleans up end cuts for tight seams.


Hidden Magnetic Knife Strip

Recess a magnetic knife holder into a kitchen backsplash or pantry wall. Plunge cut a shallow cavity in drywall with the 3-sided blade, then mount a wood face with embedded magnets. The controlled plunge lets you avoid stud and wire zones while keeping the recess crisp.


Removable Access Panel Disguised as Art

Cut a clean, framed opening to reach valves, traps, or junctions, then cover it with a magnetic picture frame. The 3-sided blade gives square, repeatable cuts, and the PlungePoint blade helps fine-tune corners so the panel sits flush and gaps are minimal.
