Meet the Diablo Rebar Demon 7/16 in. x 12 in. Carbide Hammer Drill Bit with an SDS-Plus Shank—engineered to conquer reinforced concrete and heavy masonry with precision and durability. This isn’t just another masonry bit; it’s a purpose-built solution for tough drilling tasks where rebar and dense aggregate meet their match.
-
Carbide tip delivers exceptional wear resistance in hard masonry and reinforced concrete, helping you get longer life from a single bit when drilling through demanding substrates.
-
SDS-Plus shank enables quick, secure bit changes on compatible rotary hammers, minimizing downtime and keeping you in the job longer.
-
Dimensions — 7/16 in drill size, 12 in overall length, with a 10 in flute length for efficient material removal and deeper holes.
-
Packaging — carded, single-piece design focused on practical use and easy stack-and-store convenience.
-
Brand lineage — Diablo Rebar Demon, a lineup crafted to tackle concrete work where rebar is present, delivering reliable performance when it matters most.
The extended reach of 12 inches paired with a 10-inch flute means cleaner holes with less clogging, even when you’re drilling near edges or overhead. This bit is especially well-suited for installing anchors, bolts, or conduit in walls and slabs where reinforced concrete is involved, as well as for electrical and plumbing runs that must pierce through tough, rebar-containing material.
What sets this Diablo bit apart is its dedicated focus on reinforced concrete and its durable carbide construction, designed to withstand the wear and tear of real-world drilling. It offers a clear advantage over standard masonry bits when you’re drilling through hard, concrete-rich substrates, helping you complete jobs faster with fewer tool changes.
Practical use tips for optimal results:
- Pair with a compatible SDS-Plus rotary hammer and use hammer mode for efficient material removal.
- Start with a light touch to establish the hole, then progressively increase feed rate while maintaining steady pressure.
- Keep the bit cool and avoid overheating—pause briefly if you notice signs of heat build-up.
- When approaching embedded rebar, slow down slightly and allow carbide to do the cutting to minimize wear.
