Freud DMAPL4230 Sds-plus Hammer Bit 5/8x12 in 3-pack

Product Description

The FREUD DMAPL4230 is a 5/8-inch diameter by 12-inch overall length (10-inch working length) SDS-Plus rotary hammer drill bit built with a full-carbide head and a 4-cutter geometry. Marketed under the Diablo brand, this bit uses tri-metal diffusion bonding technology to fuse the carbide head to the steel shank, resisting heat buildup and preventing tip breakage under sustained hammer drill loads. The full-carbide head design is engineered to cut through concrete that contains rebar without shattering, making it a reliable choice for anchor-setting work that requires ANSI-approved hole tolerances. Comes in a package of 3 bits. Total package weight is 1.83 pounds.

This bit is intended for use in concrete, masonry, and reinforced concrete applications where standard carbide-tipped bits fail prematurely due to rebar strikes. Typical use cases include setting anchors in structural slabs, tilt-wall panels, and concrete block where embedded rebar is likely. It fits SDS-Plus rotary hammers, both corded and cordless, and is optimized for the higher impact energy of professional-grade tools. Concrete and masonry trades, as well as structural steel crews setting post-installed anchors, are the primary users.

Key Features

• Full-carbide head construction survives direct rebar contact without tip loss or shattering
• 4-cutter head geometry accelerates material removal and improves hole straightness
• Tri-metal diffusion bonding technology bonds carbide to shank for heat and impact resistance
• Precision tip geometry meets ANSI tolerances required for code-compliant anchor setting
• Compatible with both corded and cordless SDS-Plus rotary hammers
• Packaged in a quantity of 3 for high-volume or crew use

Compatibility

Designed for use in corded and cordless SDS-Plus and SDS-Max rotary hammer drills. Fits any standard SDS-Plus chuck interface.

Installation Notes

Installation should be performed by qualified concrete or masonry tradespeople familiar with rotary hammer operation and anchor-setting procedures. Confirm the hammer drill is powered off and the bit is fully seated and locked in the SDS chuck before operation. When drilling in reinforced concrete, maintain consistent forward pressure and allow the hammer action to do the work — forcing the bit increases heat and wear. Follow anchor manufacturer specifications and applicable building codes for hole depth, diameter tolerance, and cleaning procedures before setting anchors.
