Diablo Multi Material Drill Bit DMAMM1120 1/2 x 6 Inch (Hex Shank Carbide Tipped Tile Masonry Concrete Wood Metal Fastening Anchor Drilling)

Diablo DMAMM1120 1/2-Inch x 6-Inch Multi-Material Carbide Hammer Drill Bit

The Diablo DMAMM1120 is a 1/2-inch diameter by 6-inch overall length multi-material hammer drill bit engineered with a 4-inch working depth and an Impact Strong hex shank for drilling structural anchor holes across tile, masonry, concrete, wood, and metal substrates. Manufactured in Switzerland with a heat-hardened carbide tip that delivers 4 times longer service life than standard multipurpose bits, this versatile rotary-percussion bit eliminates bit changes when transitioning between mixed jobsite materials. Featuring a self-centering Multi-Ground Grip Point Tip that prevents bit walking on smooth ceramic glaze alongside an optimized U-flute geometry for fast debris evacuation, it maintains low operating temperatures in high-torque cordless impact drivers and corded hammer drills.

Best Used For:

• Mixed Construction Substrate Anchoring: Drilling 1/2-inch passage and anchor holes directly through ceramic tile, backer board, and underlying concrete framing without swapping bits.
• Structural Timber & Metal Framing Assemblies: Sinking clean pilot holes through wood studs, sheet metal plates, and structural brick masonry in a single pass.
• Cordless Impact Driver Field Drilling: Executing multi-material rotary and hammer drilling operations using 18V/20V cordless impact drivers while maximizing battery charge efficiency.

Key Performance & Safety Features

• 4X Extended Life Carbide Tip: Formulated tungsten carbide Matrix withstands high friction heat and mechanical shock across abrasive masonry and metal.
• Multi-Ground Grip Point Tip Centering: Precision-milled tip geometry grips smooth tile and metal surfaces instantly to eliminate walking and face glaze scratching.
• Impact Strong Hex Shank Base: Engineered 1/4-inch hex shank absorbs high torque spikes and prevents chuck slippage in cordless impact drivers.
• Rapid Debris Evacuation U-Flute: Wide flute channels clear concrete dust, metal shavings, and wood chips quickly to keep the carbide tip cool.
• Rotary & Hammer Mode Versatility: Operates efficiently in both rotary-only and hammer drill percussion modes for maximum tool flexibility.
• Optimized Cordless Battery Runtime: Low-friction cutting geometry lowers motor current draw to deliver more holes per battery charge.

What's Included

• (1) Diablo 1/2" x 4" x 6" Multi-Material Carbide-Tipped Hammer Drill Bit (DMAMM1120)

Technical Specifications

Pro-Tip: Disengage hammer action when starting holes in delicate ceramic tile, then engage hammer percussion once the carbide tip penetrates into underlying concrete or masonry backer.
