Diablo SPEEDemon Hammer Drill Bit DMARG1100 5/16 Inch x 6 Inch (Carbide Tipped Impact Strong Hex Shank For Concrete Masonry Stone And Brick Drilling)

The Diablo DMARG1100 5/16-inch by 6-inch SPEEDemon Red Granite Hammer Drill Bit is engineered for high-speed, durable performance in concrete, masonry, brick, and natural stone. Featuring an impact-resistant carbide tip and a specialized Grip Point Tip PLUS geometry, this bit ensures stable, precise hole initiation while delivering four times the service life of conventional masonry bits. The Impact Strong hex shank provides a high-torque connection for both corded and cordless hammer drills and impact drivers, while the optimized U-flute design ensures rapid dust evacuation to minimize heat buildup and maximize drilling speed.

Best Used For:

• Concrete and Masonry Anchoring: Provides rapid, clean boring for expansion anchors and wedge bolts in foundation walls and structural slabs.
• Stone and Tile Installation: Enables precise hole drilling in delicate materials like marble and granite without fracturing the substrate.
• Brick and Block Renovation: Facilitates efficient drilling through residential and commercial masonry facades for utility routing or mounting fixtures.

Key Performance & Safety Features

• Impact Resistant Carbide Tip: Specialized brazing and hardening technology withstands extreme thermal and physical stress to significantly outlast standard bits.
• Grip Point Tip PLUS: Aggressive geometry acts as a centering pilot, preventing bit walking and ensuring surgical hole accuracy on smooth surfaces.
• Impact Strong Hex Shank: Industry-standard hex interface eliminates rotational slippage in high-torque chucks, enhancing user safety and stability.
• Optimized U-Flute Design: High-volume flute geometry accelerates dust removal, maintaining a cooler cutting environment for increased bit longevity.
• Cordless Optimization: Engineered for minimal friction, this bit maximizes power transfer, resulting in more holes drilled per battery charge cycle.

Technical Specifications

Pro-Tip: When drilling into hard granite or marble, use a light mist of water to cool the bit and reduce dust; this simple step prevents the carbide tip from overheating, effectively doubling its service life in high-density stone applications.
