SDS Max masonry drill bit with a 1‑1/2 in. cutting diameter, 31 in. usable length and 36 in. overall length. The bit uses a full‑carbide, four‑cutter head and a process referred to by the manufacturer as IRON BLAST to increase resistance to fatigue. It is intended for use with SDS Max rotary hammers for drilling in poured concrete and other masonry. The head geometry is designed to tolerate encounters with rebar. Manufacturer replacement policy applies if the bit fails while the wear mark is still visible (exclusions apply).
Project Ideas
Business
Conduit and sleeve retrofits (EV/HVAC/low-voltage)
Offer fast 1-1/2 in. penetrations through existing concrete for electricians and HVAC installers—perfect for mini-split line sets, EV charger conduit, and low-voltage bundles. Market the rebar-tolerant, full-carbide bit as a schedule saver vs. waiting on a core drill crew. Charge per hole plus mobilization; upsell firestop systems and sleeve installation.
Drainage and weep-hole upgrades
Partner with landscapers to add 1-1/2 in. weep holes to retaining walls and planters, including PVC sleeves, back-side drainage media, and face-side decorative outlets. Package as a fixed-price per hole with discounts for quantity. Emphasize dust control and clean bores verified by the wear mark for snug-fitting sleeves.
Restaurant patio anchor and utility retrofits
Specialize in drilling deep 1-1/2 in. holes in existing patios to install removable umbrella sleeves, heater posts, and power/gas conduit routes without heavy coring. Provide off-hours service for minimal disruption. Offer stainless hardware kits and flush caps as add-ons.
Event rigging anchor service
Provide temporary-to-permanent anchor solutions in concrete venues: drill 1-1/2 in. holes for grout-in sleeves or heavy drop-ins used for stages, art installations, or safety lines. After events, cap or plug holes flush. Bill by hole count and anchor spec; highlight quick turnaround and minimal spalling thanks to the 4-cutter head.
Mobile deep-hole drilling for DIYers and small contractors
A ‘we drill, you install’ service for homeowners and handypeople who need a handful of clean, deep holes. Flat rate includes SDS‑Max hammer, dust extraction, and this 31 in. bit; client supplies location and layout. Sell accessory kits (PVC sleeves, grommets, corrosion-resistant edge protectors) and use the wear mark to certify bore size for inspection.
Creative
Smokeless-style concrete fire pit retrofit
Add secondary combustion air to an existing concrete fire ring by drilling a ring of 1-1/2 in. intake holes near the base and angled inner jets near the burn chamber. The 31 in. usable length lets you reach through thick cast rings, and the 4-flute design clears debris efficiently. Insert stainless sleeves or high-temp liners in the holes to protect edges and improve durability.
Water-feature wall pass‑throughs
Create a clean, hidden route for plumbing through a thick concrete or block garden wall for a spillway or rain curtain. Use the 1-1/2 in. bit to bore a straight, deep channel that accepts 1 in. copper or PVC with insulation. The rebar-tolerant head helps if you encounter reinforcement, and the wear mark helps verify a consistent bore for watertight grommets.
Retaining wall weep holes with decorative spouts
Drill 1-1/2 in. weep holes in a concrete retaining wall to improve drainage, then sleeve with PVC and add bronze or copper spouts for a crafted look. The long bit can penetrate thicker sections in one pass. Finish with filter fabric and gravel on the back side to prevent clogging.
Modular planter blocks with glass insert cups
Transform solid concrete pavers or cast blocks into modular planters by drilling 1-1/2 in. sockets to accept borosilicate glass cups or plastic net pots for herbs and succulents. The four-flute bit evacuates dust while keeping holes true; use the wear mark to ensure diameter consistency across a grid for a tidy, repeating pattern.
Hidden cable routes for patio lighting and audio
Bore 1-1/2 in. tunnels through stair stringers, curbs, or slab edges to run low-voltage cables and conduit without surface raceways. The 31 in. reach lets you cross most residential features in a single shot. Add rubber grommets and UV-stable bushings for a finished, professional look.
