Creative

Reclaimed Wood Mosaic Headboard

Upcycle pallet and barn wood into a geometric headboard. Use the Dual-Tec plunge edge to free boards and notch joints even when nails are present, and the segmented edge to straighten and flush-trim pieces. The BIM blade shrugs off hidden nails while vibration-reduction slots help maintain crisp, repeatable cuts for tight mosaics.


Hidden AV Cable Pass-Through

Create a clean, pro-looking cable port between studs behind a TV. Plunge cut a perfect rectangle in drywall, run PVC conduit between openings, and flush-trim the plate opening with the segmented edge. The Starlock mount lets you quickly swap to sanding or scraping accessories for finishing.


Acoustic Diffuser Art Panel

Build a wall-mounted diffuser that doubles as art. Plunge cut staggered pockets and channels in softwood blocks, and use the segmented edge to square ends and flush-trim faces. If using reclaimed stock, the BIM blade handles wood with stray nails without ruining the teeth.


Sculptural PVC + Wood Lantern

Combine PVC pipe and a hardwood base into an LED lantern. Plunge organic cutouts in PVC for light patterns, then flush-trim the wood base and cut a wire chase. The blade’s control and narrow kerf make it easy to refine apertures and register repeat shapes.


Secret Compartment Picture Frame

Make a deep frame with a concealed cavity for keys or cash. Plunge cut the recess in the rear frame stock, then use the segmented edge to square corners and tune a snug magnetic lid. The vibration-reduction slots help keep delicate cuts precise.
