Creative
Perforated Tile Light Panel
Drill patterned arrays of holes in large porcelain tiles to create a backlit wall panel or cabinet door insert. Use 1/4 in and 3/8 in bits (DDB14, DDB38) for varied dot sizes. Mount LED strip lighting behind the tile so light glows through the holes, creating a starfield or geometric motif.
Upcycled Tile Wind Chimes
Turn leftover porcelain tile samples into elegant wind chimes. Use the 5/16 in bit (DDB516) to drill two top mounting holes and smaller 1/4 in holes (DDB14) along the edges for suspending strands. String with fishing line and metal tubes for a crisp, modern sound.
House Number Plaque with Standoffs
Make a weatherproof address plaque on a porcelain tile slab. Drill 3/8 in holes (DDB38) for metal standoffs and 1/4 in holes (DDB14) to pin metal numerals. The vacuum-brazed diamond tip keeps holes clean and chip-free for a gallery-quality finish.
Tile Serving Board with Handles
Build a cheese/charcuterie board using a porcelain tile as the top. Drill 1/2 in holes (DDB12) for low-profile handle posts or 5/16 in for screws to attach leather strap handles. Add cork or wood feet beneath for a stable, food-safe serving piece.
Hanging Tile Planter Panel
Create a wall-mounted planter panel: drill aligned 1/4 in holes (DDB14) in a porcelain tile to thread paracord or macramé, forming pockets to cradle small pots. The dry-drilling design and built-in wax help keep holes precise near tile edges.
