Meet the Diablo DMAPL4180 1/2" x 4" x 6" Rebar Demon™ SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit—the tough, no-nonsense solution for reinforced concrete and stubborn rebar. Built for pros who want speed, durability, and reliable performance when drilling through concrete and steel alike.

Key Features & Design

• Size: 1/2" diameter x 4" flute length x 6" overall length
• SDS-Plus 4-Cutter Full Carbide Head—designed to deliver fast, precise holes with a tougher head that resists rebar impacts
• Material & Construction: Rebar Demon™ full-carbide head with Tri-Metal Fusion Welding for up to 3X stronger weld to keep the full carbide head intact during extreme impact such as rebar
• Dura-Carbide™ Durability: features up to 2X more carbide that withstands up to 1800°F of intense heat, versus standard bits that fail at 800°F
• Heat & Vibration Performance: impact-resistant 4-cutter head extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration to deliver fast, precise holes
• Precision Tip: delivers the stability and accuracy required for fast, precise holes
• Application: Reinforced concrete and concrete; Ideal For: Up to 7X longer life versus standard 2-cutter hammer drill bits

Engineered for serious drilling sessions, the Rebar Demon bit stays cooler under pressure, minimizes wobble, and keeps cutting through tough materials with confidence. If your project involves anchor settings in reinforced concrete, this bit is engineered to outperform and outlast the rest—without turning your drill into a space heater.
