Diablo Rebar Demon 3/8 in. x 10 in. x 12 in. SDS-Plus 4-Cutter Full Carbide Head Hammer Drill Bit is engineered for professionals who need maximum durability and speed when drilling through reinforced concrete, standard concrete, brick, and block. Designed by Diablo as part of their revolutionary Rebar Demon line, this SDS-Plus hammer drill bit delivers faster drilling, cooler operation, and dramatically longer service life compared to standard 2-cutter bits - making it the go-to choice for anchor setting and heavy-duty concrete work where rebar contact is unavoidable.

Key Features

• Up to 7X longer life versus standard 2-cutter hammer drill bits - dramatically reduces bit replacement frequency and downtime on the jobsite, lowering overall cost per hole.
• Diablo-made Dura-Carbide with up to 2X more carbide - withstands up to 1800 deg. Fahrenheit of intense heat where standard bits fail at just 800 deg. Fahrenheit, keeping the bit intact even after rebar strikes.
• Impact Resistant 4-Cutter Full Carbide Head - extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration, delivering fast, precise holes through reinforced concrete.
• Tri-Metal Fusion Welding with up to 3X stronger weld - keeps the full carbide head securely bonded during extreme impact situations such as direct rebar contact, preventing breakage and head loss.
• Precision Tip design - delivers the stability and accuracy required for fast, precise holes, which is critical when setting anchors in reinforced concrete where hole placement tolerances are tight.
• Optimized flute design removes dust faster - keeping the carbide head cooler for ultimate strength and durability throughout the drilling cycle, reducing heat-related wear.
• Wear mark indicator - ensures precise hole depth making so anchors are set at the correct embedment depth every time.
• Optimized for maximum performance in corded and cordless SDS-Plus rotary hammers - compatible with a wide range of professional-grade tools for versatile jobsite use.

Why This Product

• Reinforced concrete drilling is one of the most demanding applications for any hammer drill bit - the Rebar Demon's 4-cutter full carbide head and Tri-Metal Fusion Welding are specifically designed to survive rebar hits that destroy standard bits, making it the right tool when rebar location is unknown or unavoidable.
• The Dura-Carbide formulation tolerates up to 1800 deg. Fahrenheit of heat - more than double the threshold of standard bits at 800 deg. Fahrenheit - which means less bit failure, fewer work stoppages, and more holes per bit in high-temperature drilling environments.
• The optimized flute design actively clears debris and keeps the cutting head cooler during sustained drilling, extending the working life of the bit and maintaining consistent hole quality from the first hole to the last.
• Made in the United States and compatible with both corded and cordless SDS-Plus rotary hammers, this 3/8 in. bit is a reliable, high-performance choice for anchor setting, concrete fastening, and penetration work across a wide range of professional applications.

Frequently Asked Questions

What makes the Rebar Demon bit different from a standard 2-cutter hammer drill bit?

The Rebar Demon features a 4-cutter full carbide head produced with Tri-Metal Fusion Welding, Dura-Carbide that withstands up to 1800 deg. Fahrenheit of heat, and an optimized flute design that removes dust faster to keep the head cooler. Together, these features deliver up to 7X longer life versus standard 2-cutter hammer drill bits, along with reduced vibration and more consistent hole quality when drilling through reinforced concrete.

Can this bit handle hitting rebar during drilling?

Yes. The impact resistant 4-cutter full carbide head is specifically designed to take small bites of rebar, delivering controlled and consistent carbide wear rather than sudden catastrophic failure. The Tri-Metal Fusion Welding - with up to 3X stronger weld strength - keeps the carbide head intact during the extreme impact of a rebar strike, and the Dura-Carbide material withstands temperatures up to 1800 deg. Fahrenheit where standard bits fail at 800 deg. Fahrenheit.

What size rotary hammer is this bit compatible with?

This bit has an SDS-Plus shank and is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammer drills. It is not compatible with SDS-Max chucks without an adapter.

What is the working length and total length of this bit?

This Rebar Demon hammer drill bit has a total length of 12 in. and a working length of 10 in., with a diameter of 3/8 in. The wear mark indicator helps ensure precise hole depth during anchor setting and concrete fastening work.
