The SDS-Plus and SDS-Max Rebar Demon 4-cutter full-carbide head hammer bits range in size from 5⁄32 in. to 11⁄8 in. for the Plus and 3⁄8 in. to 2 in. for the Max. Designed for rebar applications, the bits can drill holes into concrete without a rebar cutter. The bits are made with tri-metal diffusion bonding technology and are heat resistant to prevent breakage. A precision tip helps with accuracy, according to the manufacturer. The bits are compatible with corded and cordless SDS Plus and SDS Max rotary hammers. Diablo; www.diablotools.com
