The Diablo Rebar Demon 1 in. x 18 in. L Carbide Hammer Drill Bit with SDS-Plus Shank is built for seriously tough masonry tasks. When you’re drilling through reinforced concrete or chasing channels for anchors, this long, carbide-tipped bit delivers reliable performance, day in and day out.
Why choose the Diablo Rebar Demon 1" x 18" Carbide Hammer Drill Bit
-
Carbide performance for rebar and reinforced concrete – a durable carbide tip is engineered to bite through tough masonry and steel reinforcement without dulling quickly, minimizing repeat drilling and downtime.
-
Extended reach for deep installations – with an 18" overall length and a 16" flute length, you can access deep anchors, thick walls, and embedded conduits without flipping bits or switching tools.
-
SDS-Plus shank compatibility – designed to fit a wide range of rotary hammers and hammer drills that use SDS-Plus, enabling fast, secure bit changes and efficient work flow.
-
Precision-oriented geometry – optimized flute design aids dust removal and reduces wandering, helping you start cleanly and maintain a straight, true bore even in challenging substrates.
-
Purpose-built for serious jobs – part of the Rebar Demon line, this bit is specifically tuned for tough masonry environments where rebar and hard concrete are common obstacles.
Ideal use cases
- Installing anchor bolts or conduit passes in reinforced concrete slabs and walls
- Drilling deep pilot holes for heavy-duty fasteners in masonry structures
- Running electrical or plumbing lines through thick concrete where access is limited
Practical tips for best results
- Use in hammer mode with an SDS-Plus compatible rotary hammer or hammer drill for best impact efficiency.
- Operate at a moderate speed to reduce heat buildup; pause to cool the bit if you’re drilling long sections.
- Keep the bit tip and drill bit cool with brief intervals and clear dust regularly to maintain cutting performance.
- Let the bit do the work—avoid excessive force that can cause bit deflection or tip impact damage.
