Freud DMAPL4332 Sds-plus Hammer Drill Bit 7/16 in 3-pack

Product Description

The FREUD DMAPL4332 is a Rebar Demon SDS-Plus 4-cutter full-carbide head hammer drill bit sized at 7/16 inches diameter, 6 inches working length, and 8 inches overall length, sold in a 3-pack. It is engineered for drilling through reinforced concrete where rebar contact is expected. The full-carbide head is produced using tri-metal fusion welding, which resists heat and prevents breakage under high-impact conditions. The carbide formulation is rated to withstand up to 1800 degrees F of heat, compared to 800 degrees F for standard bits. Licensed electricians, concrete contractors, and construction tradespeople rely on this bit for anchor-setting work.

This bit is designed for use in SDS-Plus rotary hammer drills on reinforced concrete applications such as anchor setting, dowel placement, and utility penetrations in structural slabs and walls. The 4-cutter geometry takes controlled, incremental bites through rebar rather than binding or shattering, making it suitable for commercial and residential concrete work where embedded steel is common. The 3-pack quantity supports production drilling scenarios where multiple holes or bit rotation between heavy-use intervals is required.

Key Features

• 4-cutter full-carbide head handles direct rebar contact with controlled carbide wear
• Dura-Carbide formulation rated to 1800 degrees F, more than double the heat threshold of standard bits
• Tri-metal fusion welding bonds the carbide head to the shank for breakage resistance under impact
• Precision tip geometry delivers accurate hole starts and stable drilling in reinforced concrete
• Reduced vibration design supports extended use in high-powered SDS-Plus hammer drills
• 3-pack quantity supports high-volume anchor-setting jobs

Compatibility

Designed for use with SDS-Plus rotary hammer drills. Fits any tool with a standard SDS-Plus chuck interface. Intended for drilling reinforced concrete, masonry, and similar hard substrates where rebar may be present.

Installation Notes

Installation should be performed by qualified tradespeople familiar with rotary hammer operation and concrete anchor specifications. Confirm the SDS-Plus chuck on the tool is clean and the bit seats fully before drilling. Follow anchor manufacturer requirements for hole diameter, depth, and cleaning procedure before setting fasteners. Wear appropriate PPE including eye protection and hearing protection when operating hammer drills in concrete.
