Freud DMAPL9920-S7 Sds-plus Hammer Bit Set 7 Piece

Product Description

The FREUD DMAPL9920-S7 is a 7-piece SDS-Plus Rebar Demon hammer bit set built for drilling through concrete that contains rebar. Each bit features a 4-cutter, full-carbide head produced with tri-metal diffusion bonding technology, which resists heat buildup and prevents head breakage during high-impact drilling. The set includes six bit configurations spanning 3/16 inches through 1/2 inches in diameter and 4 inches or 6 inches in working length. Designed for licensed contractors, concrete tradespeople, and anchor-setting crews who need consistent, ANSI-compliant holes in reinforced concrete without sacrificing bit life.

This set is suited for commercial and residential concrete work where anchor setting in rebar-laden slabs, walls, or footings is required. The precision tip geometry delivers hole accuracy that meets ANSI standards for anchor setting applications. The SDS-Plus shank fits standard SDS-Plus rotary hammer drills commonly used in concrete drilling. Typical applications include anchor bolt installation, structural attachments, and through-penetrations in reinforced concrete. The included bit sizes cover the most commonly specified anchor diameters on construction job sites.

Key Features

• Full-carbide head with 4-cutter geometry for aggressive material removal in rebar-reinforced concrete
• Tri-metal diffusion bonding technology bonds the carbide head to the steel shank for heat resistance and breakage prevention
• SDS-Plus shank interfaces with standard rotary hammer chucks for positive bit retention under heavy impact
• Precision tip provides drilling accuracy required for ANSI-approved anchor setting
• 7-piece set covers six bit configurations: 3/16 x 4 inches, 1/4 x 4 inches, 1/4 x 6 inches, 5/16 x 6 inches, 3/8 x 6 inches, and 1/2 x 6 inches
• Ultra-hardened full-carbide head rated to withstand stress from high-powered hammer drills

Compatibility

Designed for use with SDS-Plus rotary hammer drills. Bit shank conforms to the SDS-Plus interface standard, making this set compatible with SDS-Plus chuck systems from major rotary hammer manufacturers.

Installation Notes

SDS-Plus hammer bits are installed and removed by licensed contractors or qualified tradespeople using SDS-Plus rotary hammers — no separate chuck key is required. Confirm the hammer drill is set to hammer-drill mode before use in concrete. Always wear appropriate PPE including eye protection and hearing protection when operating rotary hammers. Inspect each bit for carbide head cracking or shank wear before use and remove from service any bit showing visible damage.
