Freud DMAPL4300 Sds-plus Hammer Bit Full Carbide Head

Product Description

The FREUD DMAPL4300 is an SDS-Plus rotary hammer drill bit built for drilling through concrete that contains rebar. The 4-cutter, full-carbide head is produced using tri-metal diffusion bonding technology, which bonds the carbide to the steel shank for resistance to heat and breakage under sustained impact. At 1 inch in diameter with an 8-inch usable length and 10-inch overall length, this bit is sized for anchor-setting applications requiring ANSI-approved hole tolerances. The precision tip geometry maintains stability and accuracy during penetration, reducing bit walk and producing clean, consistent holes for wedge and sleeve anchor installations.

This bit is designed for concrete and masonry applications where embedded rebar is present — a common condition in structural slabs, foundations, tilt-wall panels, and block walls. The full-carbide head construction addresses the primary failure mode of conventional hammer bits: tip fracture or deformation on rebar contact. It is compatible with corded and cordless SDS-Plus and SDS-Max rotary hammers. Typical users include concrete anchoring crews, post-installed anchor installers, and commercial concrete contractors. Package quantity is 10 bits per unit.

Key Features

• Full-carbide 4-cutter head — resists fracture and deformation on rebar contact
• Tri-metal diffusion bonding technology bonds carbide head to shank for heat and impact resistance
• Precision tip geometry for fast, accurate hole production in concrete with rebar
• ANSI-approved anchor-setting tolerance for wedge and sleeve anchors
• Compatible with corded and cordless SDS-Plus and SDS-Max rotary hammers
• 10 bits per package for high-volume anchoring work

Compatibility

Optimized for use in corded and cordless SDS-Plus and SDS-Max rotary hammers. Designed for drilling through concrete containing rebar for post-installed anchor applications.

Installation Notes

Install and remove this bit only with the rotary hammer in the off position and the tool disconnected from power or battery removed. SDS-Plus bits seat with a push-and-twist motion — confirm the bit is fully locked before drilling. Wear appropriate PPE including eye protection and hearing protection when operating rotary hammer equipment. Anchor installations in structural concrete should comply with applicable building codes and manufacturer torque specifications for the anchor being set.
