Diablo Multi Material Drill Bit Set DMAMM1190 5 Piece (Hex Shank Carbide Tipped Concrete Tile Wood Metal Anchor Fastening)

Diablo DMAMM1190-S5 5-Piece Multi-Material Carbide Hammer Drill Bit Set

The Diablo DMAMM1190-S5 is a 5-piece multi-material hammer drill bit set engineered with 1/4-inch hex shanks and heat-resistant carbide tips for penetrating tile, masonry, concrete, wood, and metal without requiring mid-task bit changes. Featuring five standard anchor bit sizes ranging from 5/32-inch to 3/8-inch with a uniform 4-inch working depth, this kit utilizes a multi-ground Grip Point Tip to prevent bit walking on smooth surfaces like ceramic glaze or sheet metal. Optimized for high-torque cordless impact drivers and corded hammer drills, the integrated U-flute geometry rapidly evacuates abrasive dust to lower operating temperatures, extending bit life by up to 4X during complex mixed-substrate structural anchoring tasks.

Best Used For:

• Mixed Construction Substrate Anchoring: Drilling continuous anchor pilot holes through exterior brick masonry, wood framing studs, and interior drywall without swapping bits.
• Ceramic Tile & Bathroom Fixture Mounting: Penetrating smooth porcelain or ceramic tile and the underlying concrete backer board precisely for plumbing fixture installation.
• Metal & Concrete Structural Fastening: Sinking pilot holes through structural steel plates and directly into poured concrete foundation walls for heavy-duty mechanical anchors.

Key Performance & Safety Features

• 4X Extended Carbide Life: Proprietary heat-resistant carbide tip withstands severe friction and mechanical shock to outlast standard multi-purpose bits.
• Multi-Ground Grip Point Tip: Precision-milled centering tip grips smooth surfaces instantly to eliminate walking and face scratching.
• Impact Strong Hex Shank: Universal 1/4-inch hex base absorbs high torque spikes and prevents chuck slippage in cordless impact drivers.
• Rapid Debris Evacuation U-Flute: Wide flute channels clear concrete dust and metal shavings quickly to preserve tip hardness.
• Rotary & Hammer Mode Versatility: Operates efficiently in both rotary-only and percussion hammer drill modes for ultimate jobsite flexibility.

Technical Specifications

Pro-Tip: Disengage the hammer mode on your drill when initially breaking through delicate ceramic tile or glass to prevent shattering, then switch the hammer percussion back on once the carbide tip reaches the masonry backer board.
