Freud DMAPL4055 Sds-plus Hammer Bit 3/16x10x12 Full Carbide

Product Description

The FREUD DMAPL4055 is a 3/16-inch x 10-inch x 12-inch SDS-Plus hammer bit engineered for drilling into concrete where rebar is present. Built around a full-carbide head with a 4-cutter geometry, it delivers fast, clean penetration without the head fractures common to standard brazed-tip bits. Tri-metal diffusion bonding technology bonds the carbide head to the steel shank, resisting heat buildup and preventing breakage under sustained hammer-drill loads. The precision tip geometry produces stable, accurate holes that meet ANSI standards for anchor-setting applications. Sold in a 5-piece package at 0.8 pounds total.

This bit is suited for concrete and masonry work where rebar interference is expected — foundation anchoring, structural retrofit, post-installed anchor work, and through-slab drilling. The SDS-Plus shank interfaces with standard SDS-Plus rotary hammers, both corded and cordless. The full-carbide head design is particularly valuable on high-powered hammer drills where brazed-tip bits tend to fail early due to heat and impact stress. Installers working on ANSI-approved anchor-setting jobs will find the precision tip geometry meets the dimensional accuracy requirements those specifications demand.

Key Features

• Full-carbide 4-cutter head resists breakage and heat under high-impact hammer drilling
• Tri-metal diffusion bonding technology secures carbide head to shank for maximum durability
• Precision tip geometry produces fast, accurate holes in concrete with rebar for ANSI anchor-setting compliance
• Compatible with corded and cordless SDS-Plus and SDS-Max rotary hammers
• Sold as a 5-piece package for jobsite supply

Compatibility

Optimized for use with corded and cordless SDS-Plus and SDS-Max rotary hammers. Designed for drilling concrete containing rebar in applications requiring ANSI-approved anchor-setting hole tolerances.

Installation Notes

Installation is performed by concrete and masonry tradespeople using SDS-Plus or SDS-Max rotary hammer drills. Before bit changes, power down the tool and confirm the chuck is fully released. Wear appropriate PPE including eye protection and hearing protection during hammer drilling. Do not use this bit in a standard drill chuck or drill/driver — the SDS-Plus shank requires a compatible SDS chuck to transmit hammer energy correctly.
