Diablo DMAPL4050 3/16" x 6" x 8" Rebar Demon™ SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit is engineered for reinforced concrete and concrete with rebar. If you demand fast, precise holes while facing tough rebar, this bit keeps its cool—literally, by resisting heat that would melt a lesser tool.

Key Features & Design

• Rebar Demon™ 4-Cutter Full Carbide Head — up to 2X more Dura-Carbide to withstand up to 1800°F of intense heat whereas standard bits fail at 800°F.
• Impact Resistant 4-Cutter Full Carbide Head — extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration to deliver fast, precise holes.
• 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 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.
• Material & Build — Dura-Carbide design with a full-carbide head built to endure high heat and heavy impact.
• Size — 3/16" x 6" x 8"
• Drill Type — SDS-Plus hammer drill compatibility for quick, secure bit changes and powerful performance.

Designed to resist heat, reduce vibration, and outlast the competition, the Diablo Rebar Demon bit tackles reinforced concrete with confidence. If you’re drilling through steel-reinforced masonry, this bit is not just a good choice—it might be the only choice you’ll brag about at the end of the project.
