Meet the Diablo DMAPL4210 5/8" x 4" x 6" Rebar Demon SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit—built for reinforced concrete work and rebar-heavy projects. If you want fast, precise holes and a tool that actually survives the job, this bit delivers without the drama.

Key Features & Design

• Size: 5/8" diameter, 4" working length, 6" overall length (fits SDS-Plus hammer drills)
• Rebar Demon™ 4-Cutter Full Carbide Head: Impact resistant and designed to withstand the stress of high-powered hammer drills and the impact of rebar by taking small bites of rebar to deliver controlled carbide wear and reduced vibration
• Diablo Dura-Carbide™: up to 2X more carbide that withstands up to 1800°F of intense heat to combat rebar hits versus standard bits that fail at 800°F
• Tri-Metal Fusion Welding: features up to 3X stronger weld to keep the full carbide head intact during extreme impact such as rebar
• Precision Tip: delivers the stability and accuracy required for fast, precise holes in reinforced concrete for anchor setting
• Application: Reinforced concrete and concrete
• Durability: Up to 7X longer life versus standard 2-cutter hammer drill bits

Designed to stay cool under pressure and resist heat, the Rebar Demon bit keeps cutting longer and with less vibration, so you can move faster with less downtime. If you’re drilling through concrete that has rebar, this bit is engineered to bite efficiently and wear slowly—giving you reliable performance in tough jobs and tough conditions.
