Diablo Hammer Drill Bit DMAMX1080 9/16 Inch Rebar Demon (SDS Max 4 Cutter Full Carbide Head 31 Inch Working Depth 36 Inch Overall Length Concrete)

Diablo DMAMX1080 9/16-Inch SDS-Max Rebar Demon 4-Cutter Full Carbide Head Hammer Drill Bit

The Diablo DMAMX1080 9/16-Inch SDS-Max Rebar Demon 4-Cutter Full Carbide Head Hammer Drill Bit is an industrial masonry percussion bit engineered for deep-reach drilling through heavily reinforced concrete and steel rebar. Built with a solid 4-cutter Dura-Carbide head and a 31-inch working length (36-inch overall length), this SDS-Max accessory connects to corded and cordless rotary hammers. Utilizing Tri-Metal Fusion Welding that withstands temperatures up to 1,800°F, this bit solves carbide shearing and tip breakage challenges during deep foundation anchoring.

Best Used For:

• Deep Foundation Anchoring: Drilling precise 9/16-inch anchor holes through thick concrete footings and foundation walls up to 31 inches in depth.
• Reinforced Concrete Rebar Penetration: Boring cleanly through embedded structural rebar without bit binding or tip head shear.
• Commercial Structural Retrofitting: Setting chemical and mechanical anchors in dense concrete slabs, masonry walls, and brickwork.

Key Performance & Safety Features

• 4-Cutter Full Carbide Head: Solid Dura-Carbide tip extracts smaller fragments of steel rebar to deliver up to 7 times longer life than standard 2-cutter bits.
• Tri-Metal Fusion Welding: High-strength welding process creates a joint up to 3 times stronger to prevent head separation during severe rebar strikes.
• Extreme Heat Resistance: Dura-Carbide formulation withstands thermal stress up to 1,800°F encountered during continuous heavy drilling.
• Optimized 4-Flute Geometry: Rapidly evacuates concrete dust and abrasive slurry to keep the carbide tip cooler and maintain drilling velocity.
• Precision Centering Tip: Prevents bit wandering on smooth concrete surfaces to ensure exact hole placement for code-compliant anchors.
• SDS-Max Power Transfer: Engineered to absorb and transfer maximum mechanical impact energy from heavy SDS-Max rotary hammers.

What's Included

• (1) Diablo DMAMX1080 9/16 in. x 36 in. Rebar Demon SDS-Max Hammer Drill Bit

Technical Specifications

Pro-Tip: Withdraw the 36-inch bit slightly every 6 inches of depth to assist the 4-flute spiral in clearing packed concrete dust from deep foundation holes and prevent bit binding.
