Diablo Hammer Drill Bit DMARG1030 3/16 Inch x 6 Inch (Carbide Tipped Impact Strong Hex Shank For Concrete Masonry Stone And Granite Hole Boring)

The Diablo DMARG1030 3/16-inch by 6-inch SPEEDemon Red Granite Hammer Drill Bit is engineered for high-speed, durable performance in concrete, masonry, brick, and natural stone substrates. 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 thermal buildup and maximize drilling speed.

Best Used For:

• Concrete and Masonry Anchoring: Provides rapid, clean boring for small-diameter expansion anchors, tapcons, and pin fasteners in structural slabs and walls.
• Stone and Tile Installation: Enables precise hole drilling in high-density materials like marble and granite without fracturing or shattering the substrate.
• Commercial Masonry Facade Work: Facilitates efficient drilling through brick and concrete block structures for utility routing or mounting electrical components.

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 or hard surfaces.
• Impact Strong Hex Shank: Industry-standard interface eliminates rotational slippage in high-torque chucks, enhancing user safety and drilling 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 rotational drag, this bit maximizes power transfer, resulting in more holes drilled per battery charge cycle.

What's Included

• (1) Diablo 3/16-Inch x 6-Inch SPEEDemon Red Granite Carbide Tipped Hammer Drill Bit (DMARG1030)

Technical Specifications

Pro-Tip: When drilling into high-density natural stone like granite, apply consistent, firm downward pressure and let the hammer action do the work; pulling the bit back slightly every few seconds helps the U-flute eject packed dust, which prevents thermal buildup.
