Patio Tea-Light Constellation Pavers
Use the 1-3/4 in core bit to bore shallow 1–2 in recesses in concrete pavers or stepping stones to seat tea lights or small LED puck lights. Arrange holes in constellation patterns or along path edges. The wave-flute design clears dust quickly, letting you make a clean, repeatable series of pockets.
Succulent Pocket Wall
Core 1-3/4 in cups into the face of thick pavers or CMU caps to plant mini succulents and moss. A 1.5–2.5 in depth gives just enough soil volume for shallow-rooted plants. Create a grid of pockets for a living wall effect without full-depth penetrations.
Backlit Concrete Address Plaque
Cast a concrete plaque, then core 1-3/4 in cavities behind translucent number cutouts to house LED modules and wiring. The integral spline shank provides direct power transfer for precise, controlled recesses, and the one-piece construction resists wobble for crisp cavities.
Weighted Umbrella Base from Stacked Pavers
Stack several concrete pavers and core aligned 1-3/4 in holes to create a sleeve for a 1-1/4 in schedule 40 pipe (≈1.66 in OD). Grout the pipe in place to form a sleek, low-profile umbrella stand that’s heavy, stable, and patio-friendly.
Bubble Fountain Stone
Core a 1-3/4 in pocket in a garden stone or concrete block to seat a small LED ring and create a bubbling water outlet. Add a shallow pass-through channel for tubing. The wave-style flute helps evacuate slurry for smoother pockets in masonry.
