Project Ideas

Business

On‑Site Countertop Re‑Laminate Service

Offer quick kitchen/bath refreshes by overlaying worn countertops with new HPL. Pre-cut sink/faucet openings in the substrate or template, then bond laminate and use the bit to bore and flush-trim openings cleanly on site with minimal dust and downtime.


Commercial Desk & Tabletop Refacing

Refurbish office desks, school tables, and cafeteria tops with durable laminate overlays. Reopen cable grommets and accessory cutouts by boring and flush-trimming through the new laminate, delivering factory-quality edges without chipping.


RV/Van/Marine Panel Overlays

Provide lightweight, easy-clean laminate overlays for interior wall and cabinet panels in vans, RVs, and boats. Use templates to quickly bore and flush-trim for speakers, vents, lights, and outlets, ensuring precise, rattle-free openings in thin panels.


Template Kits for Trades

Design and sell acrylic template sets for common cutouts (outlets/switches, grommets, sink corners, speaker grilles). Paired with this bit, installers can rout perfect openings and flush-trim laminates reliably, reducing callbacks and speeding installs.


Custom Arcade & Control Overlays

Produce and install custom laminated overlays for arcade cabinets, pinball lock bars, and mixer/FX controller faceplates. Pre-drill substrates, apply printed HPL, and use the bit to trim holes and perimeters flush, offering small-batch, high-margin personalization.

Creative

Mid-Century Wall Clock Face

Laminate a clock face onto a plywood/MDF blank with a pre-cut center shaft hole and hour marker recesses. Use the bit to bore through the laminate at the center and trim the laminate perfectly flush to the pre-cut openings and outer edge using a circle template. The single-flute design leaves chip-free holes in HPL or veneer for a crisp, retro look.


Arcade/Controller Panel Overlay

Apply decorative HPL or polycarbonate laminate over a pre-drilled control panel. Use the bit to open and flush-trim joystick and button holes from the laminate using the substrate as a guide, yielding clean, round, chatter-free edges that won’t snag wiring boots.


Geometric Inlay Coasters

Cut simple geometric pockets in MDF coaster blanks, glue contrasting laminate sheets on top, then use the bit with a template to flush-trim the inlays to the pockets. The 1/4 in working length is perfect for thin laminates and gives tight, sharp details with minimal sanding.


Decorative Outlet/Switch Covers

Dress up basic outlet/switch plates by laminating them with patterned HPL. Bore through the laminate at the device openings and trim flush off the underlying plate using the bit as a guided cutter. Finish with beveled edges for a custom hardware set.


Laminated Photo Frame

Make a frame blank with a pre-cut inner aperture, glue on a thin laminate face, then use the bit to bore and flush-trim the inner opening perfectly to the substrate. Use corner templates for tight, splinter-free inside corners and a clean gallery finish.
