Diablo Hammer Drill Bit DMARG1020 5/32 Inch x 6 Inch (Carbide Tipped Impact Strong Hex Shank For Concrete Masonry Stone And Granite Hole Boring)

The Diablo DMARG1020 5/32-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 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 tapcon screws, anchor sleeves, and pin fasteners in foundation walls.
• Stone and Tile Installation: Enables precise hole drilling in high-density materials like marble and granite without fracturing or fracturing the substrate.
• Commercial Masonry Facade Work: Facilitates efficient drilling through brick and concrete block structures for mounting conduit clamps or junction boxes.

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

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.
