Diablo Hammer Drill Bit DMAMM1090 3/8 Inch x 6 Inch Multi Material (Carbide Grip Point Tip Masonry Concrete Tile Wood Metal Fast Boring Tool)

Diablo DMAMM1090 3/8-Inch x 6-Inch Multi-Material Carbide-Tipped Hammer Drill Bit

The Diablo DMAMM1090 3/8-Inch x 6-Inch Multi-Material Carbide Hammer Drill Bit bores clean anchor holes through layered ceramic tile, cured concrete, masonry brick, structural wood, and sheet metal. Engineered with an aggressive multi-ground Grip Point carbide tip, this multi-purpose bit delivers instant centering starts without wandering across smooth or glazed surfaces. Featuring an Impact Strong™ hex-compatible round shank, 4 inches of usable drilling depth, and high-volume debris evacuation flutes, this versatile drill bit equips electricians, plumbers, and commercial remodelers with seamless, one-bit boring across mixed construction materials.

Best Used For:

• Tile-to-Concrete Anchor Boring: Drilling through porcelain or ceramic tile directly into masonry substrate without cracking glazed faces.
• Multi-Layer Metal & Wood Framing: Penetrating sheet metal cladding, metal studs, and structural wood framing in a single pass.
• Masonry & Brick Electrical Rough-In: Setting 3/8-inch expansion anchors, tapcons, and conduit pipe clamps into concrete block.

Key Performance & Safety Features

• Multi-Ground Grip Point Tip: Precision-ground carbide tip bites into hard surfaces immediately to eliminate bit skidding and surface marring.
• Thermal-Resistant Carbide Formulation: Industrial carbide braze withstands severe friction heat and impact stress for extended boring longevity.
• Optimized Debris Clearing Flutes: High-capacity spiral flute geometry channels concrete dust and wood shavings away rapidly to run cooler.
• Dual-Mode Drill Compatibility: Operates seamlessly in standard rotary drills as well as heavy-pulsing hammer drills.
• Impact Strong™ Shank Architecture: Reinforced steel shank resists torsional shear forces and slippage inside high-torque drill chucks.

Technical Specifications

Pro-Tip: When drilling tile over a masonry backer, start the hole in rotary-only mode to cleanly penetrate the fragile glaze layer without chipping; once through the tile face, switch to hammer mode to power through the concrete backing quickly.
