Bubbling Boulder Fountain
Drill a 3/4 in channel through a large landscape rock to run pump tubing for a bubbling fountain. The 36 in length lets you pass through thick boulders; the open flutes help evacuate slurry if you wet-drill. Seat the rock over a hidden basin and add river stones for a natural water feature.
Stone-and-Wood Bench with Hidden Pins
Create a sculptural outdoor bench by drilling 3/4 in holes into a stone base and the underside of a hardwood slab. Epoxy #5 rebar or 5/8 in stainless rod into the stone to act as concealed dowels. The long bit allows deeper embedment for a rigid, minimalist look.
Rock-Anchored Garden Trellis or Kinetic Art
Drill angled 3/4 in holes into boulders to epoxy stainless rods that support a vine trellis or kinetic sculpture. The carbide head tolerates incidental rebar if you’re working near a reinforced footing, and the wear mark keeps hole sizing consistent for sleeves or grommets.
Hidden Geocache or Time Capsule
Drill a 3/4 in bore in a discreet spot in a masonry wall or boulder to house a weather-sealed capsule. Use a tight stone plug or faux rock cap to conceal. The long usable length lets you create a deep cavity for secure, long-term storage.
Low-Voltage Wall Lighting Conduits
Add dramatic uplighting to a retaining wall by drilling 3/4 in runs to pass low-voltage wires and brass sleeves to small fixtures. The elongated helix helps keep holes clean for neat terminations and safer cable pulls.
