Diablo Hammer Drill Bit Set DMARG1030-P5 3/16 Inch (5 Pack 6 Inch Length Carbide Tipped Impact Strong Hex Shank For Concrete Masonry Stone Drilling)

The Diablo DMARG1030-P5 5-Piece SPEEDemon Red Granite Hammer Drill Bit Set is engineered with impact-resistant carbide tips to deliver four times the service life of standard masonry bits in high-density substrates. Featuring a 3/16-inch diameter, a 4-inch working length, and specialized Grip Point Tip PLUS geometry, these bits ensure stable, skid-free hole initiation in concrete, brick, and natural stone. The universal Impact Strong hex shank provides a high-torque connection that prevents spinning in both corded and cordless impact drivers or hammer drills, while the integrated U-flute design rapidly ejects abrasive dust to minimize thermal buildup and maximize holes per battery charge.

Best Used For:

• Mechanical Fastener Installation: Bores precise, small-diameter anchor holes for tapcon screws and sleeve fasteners in structural concrete block.
• Natural Stone Detailing: Enables accurate, non-slip plunge drilling into premium polished granite and marble facades without surface cracking.
• Electrical and Utility Rough-ins: Facilitates high-efficiency masonry drilling through brick walls for routing wiring, conduit, and mounting clips.

Key Performance & Safety Features

• Impact Resistant Carbide Tips: Specialized brazing and hardening technology withstands extreme thermal shock and high-impact percussion forces.
• Grip Point Tip PLUS: Multi-ground tip architecture serves as a precise centering pilot, eliminating bit walk on slick or uneven stone surfaces.
• Impact Strong Hex Shank: Standardized high-torque hex geometry eliminates chuck slippage, optimizing operator safety and rotational power transfer.
• Optimized U-Flute Geometry: High-volume dust extraction pathways pull abrasive masonry debris away from the cutting tip to maintain a cool operating temperature.
• Cordless Power Maximization: Low-friction structural engineering reduces tool motor drag to deliver more drilled holes per runtime battery charge.

What's Included

• (5) Diablo 3/16-Inch x 6-Inch SPEEDemon Red Granite PLUS Carbide-Tipped Hammer Drill Bits (DMARG1030)

Technical Specifications

Pro-Tip: When boring multiple anchor holes in cured foundation walls, pull the bit back slightly every few seconds without stopping the motor; this mechanical purging allows the deep U-flute to eject heavy dust packing, lowering tip friction and preventing carbide degradation.
