Freud DMAPL4080 Sds-plus Hammer Bit 1/4x6x8 Carbide

Product Description

The FREUD DMAPL4080 is a 0.25-inch x 6-inch x 8-inch SDS-Plus hammer drill bit built for drilling through concrete containing rebar. Marketed under the Diablo Rebar Demon line, this bit features a 4-cutter full-carbide head constructed using tri-metal diffusion bonding technology, which bonds the carbide head to resist heat buildup and reduce breakage under sustained hammer drill stress. The precision-ground tip promotes straight, accurate hole entry in hard concrete substrates. This bit is engineered to meet ANSI standards for anchor-setting applications, making it a reliable choice when tolerance and hole quality matter. Licensed contractors and concrete drilling crews will find it suited for high-output production work.

This bit is designed for use in corded and cordless SDS-Plus and SDS-Max rotary hammer drills. It is well suited for residential and commercial concrete drilling tasks where rebar is present in the substrate — common scenarios include anchor bolt installation, post-base setting, and structural fastener work. The 0.25-inch cutting diameter and 8-inch overall length allow access to moderate-depth embedment holes. Sold in a package quantity of five, making it practical for job-site stocking.

Compatibility

Optimized for use in corded and cordless SDS-Plus and SDS-Max rotary hammer drills. Suitable for drilling reinforced concrete and meets ANSI standards for anchor-setting applications.

Installation Notes

Installation is typically performed by licensed concrete or general contractors, structural ironworkers, or experienced tradespeople. Always ensure the rotary hammer is set to the correct mode (hammer-drill, not rotation-only) before drilling into reinforced concrete. Verify embedment depth requirements against the anchor manufacturer specifications and applicable building code before drilling. Wear appropriate PPE including eye protection and hearing protection when operating high-powered rotary hammer equipment.
