The Diablo Rebar Demon 5/32 in. x 2 in. x 4 in. SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit is engineered for professionals who demand maximum durability, speed, and precision when drilling through reinforced concrete, concrete, brick, and block. Built with Diablo's exclusive Dura-Carbide formula, this hammer drill bit withstands up to 1800 deg. Fahrenheit of intense heat - more than double the threshold of standard bits that fail at 800 deg. Fahrenheit - making it the go-to solution for anchor setting in rebar-laden concrete where lesser bits break down fast. Designed for use with corded and cordless SDS-Plus rotary hammer drills, this 4-cutter full carbide head bit delivers controlled, consistent performance in the most punishing drilling conditions.

Key Features

• Up to 7X longer life versus standard 2-cutter hammer drill bits - fewer bit changes mean less downtime and lower cost per hole on the job site.
• Dura-Carbide with up to 2X more carbide material - withstands up to 1800 deg. Fahrenheit of intense heat versus the 800 deg. Fahrenheit limit of standard bits, keeping the bit functional even after direct rebar contact.
• Impact Resistant 4-Cutter Full Carbide Head - extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration, delivering fast, precise holes with less operator fatigue.
• Tri-Metal Fusion Welding with up to 3X stronger weld - keeps the full carbide head intact during extreme impact such as rebar strikes, preventing dangerous breakage in high-powered applications.
• Precision Tip - delivers the stability and accuracy required for fast, precise holes, making it ideal for anchor setting in reinforced concrete.
• Optimized flute design removes dust faster - keeping the carbide head cooler for ultimate strength and durability throughout the life of the bit.
• Wear mark indicator - ensures precise hole depth control so anchors seat correctly every time.
• Optimized for maximum performance in corded and cordless SDS-Plus rotary hammers - giving contractors flexibility across their full range of power tools.

Why This Product

• Rebar contact destroys standard 2-cutter bits quickly - this Rebar Demon bit is specifically engineered to handle rebar hits with controlled carbide wear and a fusion-welded head that lasts up to 7X longer, reducing replacement costs on demanding concrete drilling projects.
• The full carbide head survives heat that would cause an ordinary bit to fail - with Dura-Carbide rated to 1800 deg. Fahrenheit, crews can drill through thick reinforced concrete slabs and walls without stopping to cool down or swap bits.
• The 4-cutter geometry and optimized flute design work together to remove debris faster, reduce vibration, and maintain hole accuracy - critical qualities for anchor setting applications where placement precision matters.
• Made in Germany to tight manufacturing tolerances, this 5/32 in. bit fits standard SDS-Plus rotary hammers and is sold individually, making it easy to stock exactly the size your application requires.

Frequently Asked Questions

What makes the Rebar Demon bit different from a standard hammer drill bit?

Unlike standard 2-cutter bits, the Rebar Demon features a 4-cutter full carbide head constructed with Dura-Carbide that withstands up to 1800 deg. Fahrenheit - compared to the 800 deg. Fahrenheit failure point of standard bits. The Tri-Metal Fusion Welding process produces a weld up to 3X stronger, and the result is a bit that lasts up to 7X longer when drilling through reinforced concrete and rebar.

What shank type and tools are compatible with this bit?

This bit uses an SDS-Plus shank and is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammer drills.

What materials can this bit drill through?

This Rebar Demon bit is designed to drill through reinforced concrete, concrete, rebar, brick, and block - making it suitable for a wide range of structural and masonry drilling tasks.

What do the diameter, working length, and overall length specs mean in practice?

The 5/32 in. diameter defines the hole size produced, the 2 in. working length is the fluted cutting portion that engages the material, and the 4 in. overall length determines how deep into a structure the bit can reach. These dimensions make this bit well suited for shallow anchor holes in reinforced concrete walls and slabs.
