Freud DMAPL4090 Sds-plus Hammer Bit Full Carbide 4-cutter

Product Description

The FREUD DMAPL4090 is a 1/4-inch x 10-inch x 12-inch SDS-Plus hammer bit designed for drilling through concrete containing rebar. Built with a full-carbide 4-cutter head, this bit is engineered to handle the impact and stress of high-powered rotary hammer drills without tip breakage. Tri-metal diffusion bonding technology bonds the carbide head to the shank, reducing heat buildup and extending service life. The precision tip geometry delivers fast, accurate hole placement in concrete for ANSI-approved anchor setting applications. Sold in a package of 5, it is suited for masonry and concrete tradespeople who regularly encounter embedded rebar on the job.

This bit is intended for use in residential and commercial concrete drilling applications where rebar is present. Typical scenarios include anchor bolt installation, concrete forming, and post-installed fastener work. It is optimized for both corded and cordless SDS-Plus and SDS-Max rotary hammers, making it compatible with common tool platforms used by concrete, masonry, and general construction trades.

Installation Notes

Installation is performed by masonry and concrete tradespeople using rotary hammer drills with SDS-Plus or SDS-Max chuck systems. Confirm the bit shank is fully seated and locked in the chuck before operation. Wear appropriate PPE including eye protection and hearing protection when operating rotary hammers in concrete. Follow anchor manufacturer specifications and applicable building codes for hole diameter, depth, and cleaning procedures prior to anchor setting.
