Meet the Diablo DMAPL4280 7/8" x 8" x 10" Rebar Demon™ SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit—the go-to choice for reinforced concrete projects. Designed for professionals (and those who take their anchors seriously), it blends speed, durability, and cooler operation in one formidable bit.

Key Features & Design

• Size: 7/8" x 8" x 10"
• Head: SDS-Plus 4-Cutter Full Carbide Head
• Carbide Technology: Dura-Carbide™ features 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
• Durability & Performance: 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
• Construction: Tri-Metal Fusion Welding features up to 3X stronger weld to keep the full carbide head intact during extreme impact such as rebar
• Precision: 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

Produced with Tri-Metal Fusion Welding and leveraging Dura-Carbide™ technology, this bit is built to resist heat, stand up to rebar hits, and keep going when lesser bits would quit. If you’re setting anchors in reinforced concrete, the Rebar Demon delivers precise holes with less vibration and extended life—because your drill deserves a bit that actually keeps up with your workload.
