Freud DMAPL4140 Sds-plus Hammer Bit 3/8x4x6 Full Carbide

Product Description

The FREUD DMAPL4140 is a 3/8-inch x 4-inch x 6-inch SDS-Plus hammer drill bit from the Diablo Rebar Demon line, featuring a full-carbide 4-cutter head designed for high-output rotary hammer use. The full-carbide head is produced using tri-metal diffusion bonding technology, which resists heat buildup and prevents tip breakage under sustained impact loads. The precision-ground tip provides the stability needed for fast, accurate hole placement in concrete containing rebar, and meets ANSI standards for anchor-setting applications. This bit is built for professional concrete work where rebar interference is expected and downtime from bit failure is not an option.

The DMAPL4140 is suited for commercial and residential concrete drilling where SDS-Plus rotary hammers are used. Typical applications include anchor bolt installation, post-installed reinforcement, and through-slab penetrations in rebar-heavy concrete. The bit is optimized for use in both corded and cordless SDS-Plus rotary hammers operating at high impact energy. Concrete contractors, structural trades, and electrical or mechanical crews setting anchors in reinforced concrete slabs and walls are the primary installers. This SKU is packaged as a quantity of 5 per unit.

Installation Notes

Installation is performed by concrete, structural, or mechanical tradespeople using SDS-Plus rotary hammers. Always power down and disconnect the tool before changing bits. Wear appropriate PPE including eye protection and hearing protection when operating rotary hammer equipment. Follow ACI and applicable local code requirements for minimum edge distance and embedment depth when setting anchors in reinforced concrete.
