Diablo DMAMM1050 1/4-Inch x 6-Inch Multi-Material Carbide-Tipped Hammer Drill Bit

The Diablo DMAMM1050 1/4-Inch x 6-Inch Multi-Material Carbide Hammer Drill Bit bores precise anchor holes through ceramic tile, poured concrete, masonry brick, structural wood, and sheet metal. Engineered with an aggressive multi-ground Grip Point carbide tip, this multi-purpose bit delivers immediate self-centering starts without wandering across glazed tile or polished metal. Featuring an Impact Strong™ 1/4-inch hex-compatible shank, 4 inches of usable drilling depth, and high-efficiency dust clearing flutes, this versatile hole cutter equips electricians, plumbers, and commercial remodelers with seamless, one-bit drilling across mixed jobsite substrates using impact drivers, standard drills, or hammer drills.

Best Used For:

• Concrete & Masonry Anchor Installation: Drilling standard 1/4-inch anchor clearance holes for heavy-duty concrete screws, drop-in anchors, and sleeve fasteners.
• Bathroom Fixture & Cabinet Mounting Through Tile: Boring through ceramic and porcelain tile surfaces into wall studs or masonry backing without surface fracturing.
• Multi-Layer Wood & Metal Framing: Sinking clean pilot holes through sheet metal cladding, steel studs, and dimensional lumber in a single continuous pass.

Key Performance & Safety Features

• Multi-Ground Grip Point Tip: Precision-sharpened carbide tip bites into smooth surfaces on contact to eliminate bit walking and surface scratching.
• Impact Strong™ Hex Shank: 1/4-inch quick-change hex shank absorbs severe impact driver torque loads and prevents chuck slippage in standard drills.
• Thermal-Resistant Carbide Tip: Industrial carbide braze withstands high friction heat and continuous hammer impact for extended cutting life.
• Optimized Debris Clearing Flutes: High-capacity spiral flutes extract concrete dust and wood shavings rapidly to keep the cutting tip cool.
• Universal Tool Compatibility: Operates seamlessly across cordless impact drivers, standard rotary drill drivers, and hammer drills.

Technical Specifications

Pro-Tip: When installing 1/4-inch masonry sleeve anchors, use rotary mode to break through brittle tile surfaces smoothly before engaging hammer action for the underlying concrete; this two-stage method prevents tile edge cracking around anchor holes.
