Diablo DMAPL4220 5/8" x 6" x 8" Rebar Demon SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit is built for professionals who tackle reinforced concrete with confidence. This bit blends durability, speed, and heat resistance for fast, precise holes—even when rebar tries to crash the party.

Diablo’s revolutionary, most complete range of SDS-Plus and SDS-Max Rebar Demon™ 4-cutter full-carbide head hammer drill bits are the only bits designed to be the most durable, fastest and coolest solutions on the market. The Rebar Demon bits feature up to 2X more Dura-Carbide to withstand up to 1800°F of intense heat whereas standard bits fail at 800°F. Diablo’s impact resistant 4-cutter full-carbide head withstands the stress of high-powered hammer drills and the impact of rebar by taking small bites of rebar to deliver controlled carbide wear, reduced vibration and up to 7X longer life. Produced with Tri-Metal Fusion Welding, the full-carbide head resists heat and prevents breakage in extreme impact situations. Precision Tip delivers the stability and accuracy required to produce fast, precise holes in reinforced concrete for anchor setting.
