Freud DMAPL4160 Sds-plus Hammer Bit 3/8x10x12 Full Carbide

Product Description

The FREUD DMAPL4160 is a 3/8-inch x 10-inch x 12-inch SDS-Plus rotary hammer drill bit engineered for drilling through concrete that contains rebar. Built with a full-carbide head and a 4-cutter geometry, this bit is manufactured using tri-metal diffusion bonding technology, which bonds the carbide head to the steel shank to resist heat buildup and prevent tip breakage under sustained impact. The precision-ground tip maintains hole accuracy and stability needed for ANSI-approved anchor-setting applications. This bit is sold in a 5-piece package and weighs 1.65 pounds total. Licensed concrete and masonry tradespeople, anchor installers, and structural contractors rely on this bit for high-cycle drilling in reinforced concrete.

The DMAPL4160 is designed for use in reinforced concrete slabs, walls, columns, and footings where rebar strike is expected. It performs in both corded and cordless SDS-Plus rotary hammers and is also compatible with SDS-Max rotary hammers using an appropriate chuck adapter. Typical applications include anchor bolt installation, through-slab penetrations, and mechanical fastener prep work on commercial and residential concrete structures. This is a 5-piece pack, making it suitable for crews running multiple drills or jobs requiring frequent bit rotation to maintain drilling speed.

Key Features

• Tri-metal diffusion bonding technology bonds carbide head to shank, resisting heat and breakage
• Precision tip geometry provides accurate hole placement for ANSI-approved anchor setting
• Compatible with corded and cordless SDS-Plus rotary hammers
• 3/8-inch diameter x 10-inch working length x 12-inch overall length
• Sold as a 5-piece pack for job-site continuity

Compatibility

Designed for use in corded and cordless SDS-Plus rotary hammers. Also optimized for SDS-Max rotary hammer platforms. Suitable for drilling through reinforced concrete for ANSI-approved anchor-setting applications.

Installation Notes

Install and remove this bit only while the rotary hammer is powered off and the chuck is fully disengaged. Confirm the SDS-Plus chuck is clean and free of debris before inserting the bit shank. When drilling into reinforced concrete, reduce feed pressure slightly upon rebar contact to prevent bit deflection. Follow applicable OSHA and jobsite safety protocols, including eye and hearing protection, when operating rotary hammer equipment.
