Freud DMAPL4030 Sds-plus Hammer Bit 3/16 X 4 Inch Carbide

Product Description

The FREUD DMAPL4030 is a 3/16-inch x 2-inch x 4-inch SDS-plus hammer bit engineered for drilling through concrete containing rebar. Built with a full-carbide head and a 4-cutter geometry, this bit is produced using tri-metal diffusion bonding technology, which bonds the carbide head to resist heat buildup and prevent tip breakage under heavy impact loads. The precision-ground tip delivers accurate, stable hole placement required for ANSI-approved anchor setting. This bit is designed for licensed contractors, concrete tradespeople, and experienced installers working with high-powered rotary hammer drills in demanding structural applications.

The DMAPL4030 is suited for drilling into reinforced concrete slabs, walls, and foundations where rebar contact is expected. The full-carbide head construction handles the impact stress of rebar strikes that would fracture conventional hammer bits. It is optimized for use in both corded and cordless SDS-plus rotary hammers, making it practical for job sites where power access varies. This bit is sold in a package of 5, supporting crews running multiple drills or requiring consistent hole quality across anchor arrays.

Key Features

• Full-carbide head withstands direct rebar contact without fracturing
• 4-cutter geometry increases material removal rate and reduces drilling time in reinforced concrete
• Tri-metal diffusion bonding technology resists heat and extends bit life under sustained impact
• Precision tip supports accurate hole placement for ANSI-approved anchor setting
• Compatible with corded and cordless SDS-plus rotary hammers
• Sold in a package of 5 units

Compatibility

Optimized for maximum performance in corded and cordless SDS-plus rotary hammers. Also compatible with SDS-max rotary hammers using an appropriate chuck adapter.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with rotary hammer operation and concrete anchor requirements. Verify the hammer drill is powered off and the chuck is fully released before inserting or removing the bit. Eye and hearing protection are required when operating rotary hammer drills in concrete. Follow applicable building codes and anchor manufacturer instructions for minimum embedment depth and edge distance when setting anchors in reinforced concrete.
