When you’re tackling deep, heavy-duty drilling in reinforced concrete, the Diablo Rebar Demon 7/8 in. x 18 in. L Carbide Hammer Drill Bit with SDS-Plus Shank is built to perform. This long-reach bit is purposefully engineered to withstand the rigors of modern construction, delivering crisp, fast holes where standard bits struggle.
Why this bit stands out
-
Carbide tip for extended life: The carbide cutting edge stays sharper longer under the load of concrete, masonry, and occasional embedded steel, so you waste less time sharpening or replacing bits.
-
Long-reach design: With an 18" overall length and a 16" flute, you can drill deep holes for through-anchor bolts, conduits, and other long-in-wall installations without an extension bit.
-
SDS-Plus shank: This shank type provides a secure, precise fit in compatible hammer drills, enabling efficient energy transfer and minimizing wobble during heavy bit engagement.
-
Large-diameter capability: At 7/8" drill size, it creates substantial holes for robust anchors and fasteners in concrete and masonry, reducing the number of passes and accelerating your project timeline.
-
Built for the Rebar Demon lineage: Optimized for demanding jobs where reinforced concrete and dense masonry are the norm, offering dependable performance when others falter.
Ideal use cases
- Drilling deep holes for anchor bolts in poured concrete walls and floors.
- Creating through-holes for electrical conduits, plumbing lines, or ventilation runs in reinforced masonry.
- Situations where you need a long, durable bit that can handle contact with rebar and other dense materials.
Practical guidance for best results
- Use with a compatible hammer drill set to appropriate drilling mode; maintain a steady, perpendicular angle for clean holes.
- Apply moderate pressure and let the carbide edge do the cutting—pushing too hard can cause bit binding or bit wander.
- Keep the bit cool and manage dust with active drilling techniques; pause to clear debris if needed during long-hole drilling.
