Freud DMAPL4180 Sds-plus Hammer Bit Full Carbide Head

Product Description

The FREUD DMAPL4180 is a 0.5-inch x 4-inch x 6-inch SDS-Plus rotary hammer drill bit built for drilling through concrete containing rebar. This is a 4-cutter, full-carbide head design produced using tri-metal diffusion bonding technology, which bonds the carbide head to the steel shank for improved heat resistance and breakage prevention. The bit is engineered to handle the combined stress of high-powered rotary hammer operation and direct rebar contact. The precision tip geometry maintains hole accuracy and stability, making it suitable for ANSI-approved anchor setting applications. It ships in a package of 3 bits.

This bit is intended for use by concrete drilling contractors, anchor installation crews, and trade professionals working in structural concrete, masonry, and post-installed anchor applications. It is optimized for use in both corded and cordless SDS-Plus and SDS-Max rotary hammers. Typical applications include drilling through reinforced concrete slabs, walls, and footings where rebar contact is expected during the drilling process. The full-carbide head maintains cutting performance through rebar strikes that would damage standard hammer bits.

Key Features

• Full-carbide head construction resists heat and breakage during rebar contact
• 4-cutter geometry increases material removal rate in reinforced concrete
• Tri-metal diffusion bonding technology bonds carbide head to shank for extended service life
• Precision tip designed for ANSI-approved anchor setting accuracy
• Compatible with corded and cordless SDS-Plus and SDS-Max rotary hammers
• Package includes 3 bits per unit of measure

Compatibility

Designed for use with corded and cordless SDS-Plus and SDS-Max rotary hammer drills. Suitable for anchor setting applications requiring ANSI-compliant hole tolerances in reinforced concrete.

Installation Notes

Installation should be performed by qualified concrete drilling or anchor installation professionals. Before drilling, shut down adjacent systems or equipment that may be affected by vibration. Verify the SDS-Plus chuck is fully engaged and the bit is seated before operating the hammer drill. Follow applicable building codes and anchor manufacturer specifications for hole depth, diameter tolerance, and cleaning procedure prior to anchor setting.
