SDS Max masonry drill bit with a four-cutter carbide head. The bit uses a heat/strengthening process (referred to as Iron Blast Technology) to improve fatigue resistance. The full-carbide, four-cutter head is intended to extend service life and better tolerate contact with rebar. Includes a wear mark to indicate remaining usable diameter and a manufacturer replacement policy if the bit fails while the wear mark is still visible (exclusions apply).
Project Ideas
Business
Adhesive Anchor and Railing Installations
Offer a service drilling precise 7/8 in holes for post-installed adhesive anchors (e.g., 5/8 in threaded rod) in slabs, stairs, and balcony edges. The rebar-tolerant, four-cutter head minimizes downtime when you hit steel, and the wear mark provides QA documentation that hole diameters met spec for code-compliant handrails, guards, and bollards.
Seismic Retrofit & Rebar Doweling
Provide epoxy doweling for structural tie-ins (shear walls, ledger replacements, sill plate upgrades). Drill 7/8 in holes for #5 bars per engineer specs; the bit’s durability through concrete, aggregate, and incidental rebar keeps productivity high. Bundle with pull-testing and reporting for inspectors and GCs.
Retaining Wall Weep Hole Service
Mitigate hydrostatic pressure by drilling 7/8 in weep holes in concrete or CMU retaining walls and installing sleeves/vents. The four-flute design speeds chip evacuation, reducing clogging in wet or sandy cores. Package with gravel backfill and filter fabric upgrades for a turnkey moisture solution.
Landscape Water Feature Fabrication
Specialize in drilling through natural stone and precast blocks to build custom bubbling boulders, spillways, and illuminated rock columns. The full-carbide head handles hard rock, and the wear mark helps you match fittings and tubing every time. Sell complete kits (pump, basin, lighting) and on-site installation.
Industrial Equipment & Racking Anchoring
Anchor machinery bases, guard rails, and warehouse racking into cured concrete with adhesive anchors requiring 7/8 in holes. The bit’s rebar-hit tolerance reduces surprises in heavily reinforced slabs, and the wear mark supports QA logs for audited facilities. Offer layout, drilling, cleaning, adhesive injection, and torque verification as a bundled service.
Creative
Boulder Bubbling Fountain
Drill a clean 7/8 in pass-through in a landscape boulder to route pump tubing for a bubbling fountain. The four-cutter carbide head and four-flute design chew through hard stone and evacuate slurry efficiently, while the wear mark helps ensure a consistent diameter for bulkhead fittings or grommets. Pair with a submersible pump, basin, and optional LED lighting for a premium garden feature.
Stone Wind Chimes/Mobile
Turn river rocks or thin pavers into a tonal garden mobile by drilling suspension holes and threading stainless rod or cable. The bit’s full-carbide, four-cutter head resists wandering on uneven stone and survives incidental aggregate or rebar if you’re repurposing reinforced fragments. Mix sizes and spacing for varied tones and a sculptural look.
Concrete Planter Art with Patterned Drainage
Cast minimalist concrete planters, then drill geometric 7/8 in drainage patterns or cable pass-throughs for integrated lighting. The wear mark ensures uniform openings so rubber grommets and mesh screens fit snugly. If planters include reinforcing mesh, the rebar-tolerant head helps avoid damage if you make contact.
Illuminated Cobblestone Path Markers
Drill vertical 7/8 in bores into cobblestones or pavers to inset small LED pucks or acrylic light rods. Route low-voltage wiring through drilled channels. The four-flute design clears dust to prevent blowout at exit points, leaving cleaner edges for lenses or diffusers.
Ventilated Fire Pit Ring
Improve airflow in a cast-concrete or block fire pit by drilling an evenly spaced ring of 7/8 in intake holes near the base. Use the wear mark to keep hole diameters consistent for aesthetics and predictable combustion. If the ring is lightly reinforced, the four-cutter head tolerates incidental rebar contact.
