Diablo The revolutionary, most complete range of SDS-Plus and SDS-Max rebar Demon 4 cutting bits made of solid carbide head 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 2000 degrees F of intense heat while standard bits fail at 215°C. Diablo impact-resistant 4-flute solid carbide head withstands the stress of powerful hammer drills and the impact of rebar by taking small bites from rebar to achieve controlled carbide wear, reduced vibration, and up to 7 times longer service life. Made with Tri-Metal Fusion Welding, the solid carbide head resists heat and prevents breakage in extreme impact situations. The precision tip delivers the stability and accuracy required to create fast, precise holes in reinforced concrete for anchor adjustment.
