The Diablo Rebar Demon 1/4 in. x 2 in. x 4 in. SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit is engineered for professionals who demand durability, speed, and precision when drilling into reinforced concrete, concrete, brick, and block. Built with Diablo's proprietary Dura-Carbide technology and a full carbide head bonded through Tri-Metal Fusion Welding, this SDS-Plus bit is purpose-built to cut through rebar without sacrificing bit life or drilling accuracy - making it the go-to choice for anchor setting and structural drilling in the most demanding jobsite 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
• Dura-Carbide full carbide head features up to 2X more carbide that withstands up to 1800 deg. Fahrenheit of intense heat, compared to standard bits that fail at 800 deg. Fahrenheit - keeps cutting through rebar strikes that would destroy lesser bits
• Impact Resistant 4-Cutter Full Carbide Head extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration - delivers fast, precise holes without rough handling or operator fatigue
• Tri-Metal Fusion Welding features up to 3X stronger weld to keep the full carbide head intact during extreme impact such as rebar - prevents head separation even under repeated heavy-duty hammer strikes
• Precision Tip delivers stability and accuracy required for fast, precise holes - essential for reliable anchor setting in reinforced concrete where hole placement matters
• Optimized flute design removes dust faster, keeping the carbide head cooler for ultimate strength and durability - reduced heat buildup extends bit life and maintains cutting performance over long drilling runs
• Wear mark indicator ensures precise hole making - gives the operator a clear reference for consistent hole depth without guesswork
• Optimized for maximum performance in corded and cordless SDS-Plus or SDS-Max rotary hammers - compatible with the power tools already on your jobsite

Why This Product

• Designed specifically to survive rebar contact - where standard 2-cutter bits crack, chip, or fail outright, the 4-cutter full carbide head takes controlled small bites of rebar and keeps drilling, extending usable bit life up to 7X longer
• Handles extreme heat that destroys conventional bits - Dura-Carbide withstands up to 1800 deg. Fahrenheit versus the 800 deg. Fahrenheit threshold where standard carbide bits break down, making this bit far more reliable in high-friction, high-heat drilling conditions
• Tri-Metal Fusion Welding provides up to 3X stronger head attachment, so the carbide head stays bonded under the repeated impact of high-powered rotary hammer drilling - reducing the risk of catastrophic bit failure mid-hole
• Made in the United States and built to perform in reinforced concrete, concrete, brick, and block - a single 1/4 in. bit size that covers the range of anchor setting and structural drilling applications found on most commercial and residential job sites

Frequently Asked Questions

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

The Rebar Demon uses a 4-cutter full carbide head rather than the 2-cutter design found on standard hammer drill bits. This allows it to take smaller, more controlled bites of rebar, reducing vibration and carbide wear while delivering up to 7X longer bit life. In addition, Dura-Carbide withstands up to 1800 deg. Fahrenheit - more than twice the heat tolerance of standard carbide bits that fail at 800 deg. Fahrenheit.

Will this bit work with my cordless rotary hammer?

Yes. The Rebar Demon 1/4 in. SDS-Plus bit is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammer drills. Its SDS-Plus shank provides a secure, tool-free bit insertion compatible with the SDS-Plus chuck standard used across most major rotary hammer brands.

What materials can I drill with this bit?

This bit is designed for use in reinforced concrete, concrete, rebar, brick, and block. It is especially effective in reinforced concrete applications where rebar strikes are likely, thanks to its impact-resistant full carbide head and Tri-Metal Fusion Welding construction.

Is this product made in the United States?

Yes. This Diablo Rebar Demon SDS-Plus hammer drill bit is a product of the United States.
