Freud DMAPL4220 Sds-plus Hammer Bit 5/8 X 6 X 8 Inches

Product Description

The FREUD DMAPL4220 is a 5/8-inch diameter SDS-Plus rotary hammer drill bit built for drilling through concrete that contains rebar. Part of the Diablo Rebar Demon series, this bit features a 4-cutter, full-carbide head produced using tri-metal diffusion bonding technology. That process bonds carbide to the head at a molecular level, resisting heat buildup and reducing the risk of tip breakage under the sustained impact of high-powered rotary hammer use. The bit measures 5/8 inches in diameter with a 6-inch working length and 8-inch overall length, and weighs 0.42 pounds. It is intended for use by concrete and masonry tradespeople who need reliable, accurate holes for ANSI-approved anchor setting.

This bit is designed for applications where standard carbide-tipped bits fall short — specifically in reinforced concrete where rebar contact is likely or unavoidable. The 4-cutter head geometry maintains cutting speed and directional accuracy even when the tip contacts steel rebar, reducing deflection and preserving hole position. It is suited for residential and commercial concrete work including foundation anchoring, structural fastening, and mechanical system attachment points where anchor placement must meet ANSI tolerances. The precision tip supports accurate hole placement in slabs, walls, and columns. Each package contains 3 bits.

Installation Notes

Installation should be performed by qualified concrete or masonry tradespeople familiar with rotary hammer operation and anchor-setting procedures. Disconnect or de-energize the tool before inserting or removing the bit from the chuck. Wear appropriate PPE including eye protection and hearing protection during use. Follow all applicable anchor manufacturer guidelines and local building code requirements when setting anchors in reinforced concrete.
