Freud DMAPL4250 Sds-plus Hammer Bit 3/4 X 10 Inch Carbide

Product Description

The FREUD DMAPL4250 is a 3/4 inch x 8 inch x 10 inch SDS-Plus rotary hammer drill bit built for drilling through concrete containing rebar. It features a full-carbide head with four cutting edges, manufactured using tri-metal diffusion bonding technology that resists heat buildup and reduces the risk of breakage under sustained impact loads. The precision-ground tip maintains stability and accuracy during hole formation, making it suitable for ANSI-approved anchor-setting applications. This bit is designed for use in corded and cordless SDS-Plus and SDS-Max rotary hammers and is sold in a package of 10 units. Concrete drilling contractors, anchor installation crews, and commercial construction trades are the primary installers.

This bit is built for applications where concrete and embedded rebar must both be penetrated cleanly. Typical uses include post-installed anchor drilling in reinforced concrete slabs, walls, columns, and footings in both residential and commercial construction. The 3/4 inch diameter and 10 inch overall length suit medium-depth anchor installations where standard carbide-tipped bits are prone to premature wear or tip failure on contact with rebar. The full-carbide head design extends service life in high-cycle drilling environments where bit replacement downtime is a cost factor.

Key Features

• Full-carbide head with 4-cutter geometry for penetration through both concrete and rebar
• Tri-metal diffusion bonding technology bonds the carbide head for heat resistance and breakage prevention
• Precision tip geometry supports accurate hole placement for ANSI-approved anchor setting
• Compatible with corded and cordless SDS-Plus and SDS-Max rotary hammers
• 10 inch overall length with 8 inch working depth for medium-depth anchor applications
• Sold as a package of 10 bits

Compatibility

Designed for use in corded and cordless SDS-Plus and SDS-Max rotary hammers. The SDS-Plus shank interface is the standard fitment for this bit series.

Installation Notes

Installation is performed by qualified concrete drilling and anchor installation trades. Verify rotary hammer shank compatibility before use — this bit uses an SDS-Plus shank. Wear appropriate PPE including eye protection, hearing protection, and dust respiratory protection when drilling concrete. Follow anchor manufacturer specifications and applicable building codes for hole diameter, depth, and cleaning procedures before setting anchors.
