Conquer reinforced concrete and stubborn masonry with confidence using the Diablo Rebar Demon 3/8 in. x 18 in. Carbide Hammer Drill Bit with SDS-Plus Shank. Built for serious contractions and retrofit work, this bit blends industrial-grade carbide with a long reach to power through rebar-infused substrates and thick concrete with precision.
Why this bit stands out
-
Carbide tip for extended wear life — engineered to hold its edge when encountering embedded rebar and dense aggregates, reducing dwell time and the need for frequent bit changes.
-
16 in flute length, 18 in overall length — designed for deep holes and efficient debris removal in deep concrete sections, masonry cores, and anchor installations.
-
SDS-Plus shank — provides a secure, chatter-free connection to modern rotary hammers and SDS-Plus drills, delivering consistent impact energy for faster drilling.
-
Single-piece, carded packaging — ready to slot into your toolbox or job-site kit, ensuring you always have the right bit on hand for demanding projects.
Ideal applications and who benefits
- Professional masons, general contractors, and tradespeople tackling anchors, electrical or plumbing passes, or rebar-dense concrete installations.
- DIY enthusiasts working on basement walls, concrete floors, or structural repairs where long, through-holes are required.
- Projects demanding long reach without sacrificing durability—drill deep into thick concrete slabs, pillars, or retrofits where encountering rebar is likely.
How this tool solves real-world problems
- Protects project timelines by delivering longer service life in abrasive environments, reducing downtime from dull or failed bits.
- Delivers cleaner, more accurate holes in reinforced concrete, enabling precise anchor placement and faster installation of fixtures and equipment.
- Maintains performance under demanding conditions thanks to carbide construction and robust SDS-Plus compatibility, minimizing tool wear and maximizing workflow efficiency.
Practical tips for best results
- Use in hammer mode with an SDS-Plus compatible drill for optimum impact delivery and bit stability.
- Start with a light bite to establish a clean pilot hole, then increase feed pressure gradually—let the bit do the work to avoid accelerated wear or binding.
- Periodically withdraw the bit to clear debris and cool the tip on dense material—hot drilling can shorten bit life.
- For deep holes, plan the drilling sequence to maintain straight, true holes and minimize bit wander.
