Office cable-grommet upgrades
Partner with offices and millwork shops to add 90–92 mm desk and conference-table grommets. Provide clean, chip-free holes in laminate, MDF, and veneer, and supply matching flip-top or Qi-charging grommets. Price per hole with volume discounts.
Garage cubby wall kits
Manufacture and sell ready-to-install plywood panels pre-drilled with 3-5/8 in holes and include cut-to-length 3 in PVC tubes. Offer sizes for standard stud spacing, color options, and optional labels. Sell online and to builders as a modular storage system.
Custom planter walls
Produce vertical herb/succulent boards drilled for 3 in nursery pots using 2x stock (one-pass cuts speed production). Offer finishes from rustic to painted, include drip trays, and sell locally at markets and garden centers with installation as an upsell.
Small-batch coaster brand
Turn the ejected plugs into premium coaster sets: hardwoods, live-edge offcuts, metal-and-wood hybrids. Add CNC-engraved logos for corporate gifting. Streamlined production thanks to fast plug ejection; package with branded holders for higher margins.
Creative
Reclaimed-wood coaster set
Use the hole saw to pop out 3-5/8 in disks from 1/4–3/4 in reclaimed boards. The large slot makes it easy to eject clean plugs. Sand the edges, add resin or inlay rings, and finish with oil or polyurethane. Bundle in sets with a simple holder made from a scrap offcut.
Wall-mounted succulent board
Drill 3-5/8 in holes through 2x lumber to hold standard 3 in nursery pots (the rim sits nicely in the opening). The deeper saw cuts 2-by stock in a single pass for quick production. Add a French cleat on the back and a drip tray below.
Wine bottle display rack
Cut angled 3-5/8 in through-holes in a wide board (e.g., 2x10). The opening cradles the 3–3.2 in body of most wine bottles. Add felt-lined edges or a thin backing rail to keep bottles secure, and mount horizontally or as a leaning floor rack.
PVC-cubby tool organizer
Drill a grid of 3-5/8 in holes in a plywood panel to friction-fit 3 in Schedule 40 PVC pipe (OD ≈ 3.5 in). Glue short PVC sections into the holes to create durable wall cubbies for tools, spray cans, and hardware bins.
Elevated pet bowl stand
Cut 3-5/8 in openings in a 1x or 2x board to drop in small stainless pet bowls. The bi-metal edge handles thin metal trim if you add a ring. Personalize with a name plaque and adjustable legs for pet comfort.
