Diablo Rebar Demon SDS-Plus 4-Cutter Full-Carbide Hammer Drill Bit

Diablo Rebar Demon SDS-Plus 4-Cutter Full-Carbide Hammer Drill Bit

The Diablo Rebar Demon™ is an SDS-Plus 4-cutter full-carbide head hammer drill bit engineered for drilling through reinforced concrete where rebar strikes are unavoidable. This Diablo bit family is available in Bit Diameters ranging from 1/4 in. to 3/4 in. and Bit Lengths from 6 in. to 18 in., covering nearly every anchor-hole drilling need on the jobsite. Every size in this line is built with up to 2X more Dura-Carbide™ than standard bits, withstanding up to 1800°F of heat generated during high-impact rebar contact versus standard bits that fail at 800°F. The impact-resistant 4-cutter full-carbide head takes smaller, controlled bites of rebar across the entire range, reducing vibration while delivering fast, precise holes in reinforced concrete, brick, and block.

Key Features

• Size Range: Available in Bit Diameters from 1/4 in. up to 3/4 in. and Bit Lengths from 6 in. to 18 in. for precise anchor-hole drilling in reinforced concrete.
• Durable Construction: Full Carbide Head with Tri-Metal Fusion Welding delivers up to 3X stronger weld strength to keep the carbide head intact during extreme rebar impact.
• 4-Cutter Configuration: Impact-resistant 4-cutter full-carbide head extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration.
• SDS-Plus Shank: Fits corded and cordless SDS-Plus rotary hammers for fast bit changes and secure engagement across the entire size range.
• Heat Resistance: Diablo-made Dura-Carbide™ withstands up to 1800°F of intense heat versus standard bits that fail at 800°F.
• Optimized Flute Design: Removes dust faster, keeping the carbide head cooler for ultimate strength and durability across every length in the range.
• Wear Mark Indicator: Ensures precise hole making throughout the life of the bit.
• Extended Life: Up to 7X longer life versus standard 2-cutter hammer drill bits.
