Meet the Diablo DMAPL4160-P25 Rebar Demon™ SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bits—your trusted partner for tackling reinforced concrete with embedded rebar. This 25-pack delivers consistent, precise holes fast, even in the toughest jobs.

Unmatched durability for reinforced concrete and rebar

Diablo’s Rebar Demon bits fuse advanced carbide technology with a purpose-built design. The 4-cutter full-carbide head features up to 2X more Dura-Carbide, enabling the bit to endure extreme heat—up to 1800°F—where standard bits falter at around 800°F. Built to withstand the impact and stress of high-powered SDS-Plus hammer drills, these bits bite through concrete while smartly negotiating rebar by taking small bites, reducing carbide wear and delivering measurable longevity—up to 7X longer life compared with typical heads.

• Full-carbide head with Tri-Metal Fusion Welding for superior heat resistance and breakage prevention in extreme impact.
• 4-cutters engineered to minimize vibration, stabilize the start, and share the cutting load for cleaner, faster holes.
• Precision Tip delivers stable starts and accurate hole placement, ideal for anchor setting in reinforced concrete.
• 2X more Dura-Carbide withstands brutal heat and rebar contact, extending overall life in demanding jobs.

Why this matters for your projects

When anchor-work or fixture installation requires reliable penetration through reinforced concrete, every second counts. The Rebar Demon bits divide heavy-duty concrete from rebar with controlled carbide wear, which means fewer bit changes, less downtime, and more consistent hole quality. The result is faster installation, tighter tolerances, and less temptation to push a bit beyond its design—all while keeping tools cooler and wear lower under load.

Ideal use cases

• Anchor setting in reinforced concrete where rebar is present
• High-velocity drilling in concrete slabs, foundations, and structural walls
• Deeper drilling tasks where longer bit life reduces maintenance and replacements
• Professional applications across construction, electrical, plumbing, and masonry jobs

What sets it apart from standard bits

The Rebar Demon series stands apart by combining a robust, full-carbide head with an optimized 4-cutter geometry and a heat-tolerant construction. The result is:

• Better performance in high-throughput scenarios thanks to reduced downtime from fewer bit changes.
• Quieter, steadier drilling thanks to reduced vibration and a stable start.
• Superior endurance in tough environments where rebar and dense concrete challenge typical bits.

Practical tips for best results

• Use a compatible SDS-Plus hammer drill with sufficient impact energy to maximize the 4-cutter design.
• Let the bit do the work—avoid excessive feed pressure to minimize carbide wear and heat buildup.
• Allow brief pauses during deep holes to cool the bit and maintain consistent performance.
• Pair with proper PPE and follow site safety guidelines to ensure efficient, safe operation.
