The Diablo 1" x 8" x 13" Rebar Demon SDS-Max 4-Cutter Full Carbide Head Hammer Drill Bit is engineered for professionals who demand durability, speed, and precision when drilling through reinforced concrete, concrete, brick, and block. Designed for use with SDS-Max rotary hammer drills, this bit combines advanced carbide technology with impact-resistant construction to deliver consistently fast, accurate holes - even when rebar stands in the way. Whether you are setting anchors in structural concrete or working through heavily reinforced slabs, the Rebar Demon is built to outlast and outperform standard 2-cutter bits in the most demanding jobsite conditions.

Key Features

• Up to 7X longer life versus standard 2-cutter hammer drill bits - dramatically reduces bit replacement frequency, lowering cost and downtime on the job.
• Diablo Dura-Carbide with up to 2X more carbide - withstands up to 1800 deg. Fahrenheit of intense heat from rebar impact, whereas standard bits fail at 800 deg. Fahrenheit, keeping the bit cutting longer under extreme conditions.
• Impact Resistant 4-Cutter Full Carbide Head - extracts smaller bites of rebar for controlled, consistent carbide wear and reduced vibration, delivering fast and precise holes through reinforced concrete.
• Tri-Metal Fusion Welding with up to 3X stronger weld - keeps the full carbide head intact during extreme rebar impacts, preventing head separation and premature failure in high-stress drilling situations.
• Precision Tip - delivers the stability and accuracy required for fast, precise holes, making it ideal for critical anchor-setting applications in reinforced concrete.
• Optimized flute design - removes dust faster, keeping the carbide head cooler for ultimate strength and durability over extended use.
• Wear mark indicator - ensures precise hole depth control so anchors are set correctly every time.
• Optimized for corded and cordless SDS-Max rotary hammers - delivers maximum performance across a wide range of professional-grade tools.

Why This Product

• When drilling through rebar is unavoidable, the 4-cutter full carbide head takes controlled, smaller bites of rebar rather than absorbing full impact - extending bit life up to 7X compared to standard 2-cutter designs and reducing costly stoppages on the job.
• The Dura-Carbide formulation handles heat up to 1800 deg. Fahrenheit - more than double the 800 deg. Fahrenheit threshold where standard bits break down - making this bit a reliable choice for sustained, high-powered hammer drilling in demanding reinforced concrete applications.
• Tri-Metal Fusion Welding provides up to 3X stronger bonding of the full carbide head, giving users confidence that the bit will stay intact even during extreme rebar strikes rather than shattering at the weld point.
• The optimized flute design actively clears debris and keeps the head cooler during drilling, meaning less heat-related wear and more consistent hole quality throughout the life of the bit.

Frequently Asked Questions

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

Standard 2-cutter hammer drill bits typically fail under intense heat at around 800 deg. Fahrenheit and are not designed to handle direct rebar contact. The Diablo Rebar Demon uses a 4-cutter full carbide head with Dura-Carbide that withstands up to 1800 deg. Fahrenheit of heat, takes controlled bites of rebar to reduce vibration and carbide wear, and features Tri-Metal Fusion Welding with up to 3X stronger bonding - delivering up to 7X longer life compared to standard bits.

What shank type does this bit use, and which tools is it compatible with?

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

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

This bit has a total length of 13" and a working length of 8", with a 1" diameter. The wear mark indicator on the bit helps ensure precise hole depth when setting anchors.

What materials can this bit drill through?

This Diablo hammer drill bit is designed to drill through reinforced concrete, concrete, rebar, and brick/block, making it well suited for anchor setting and structural drilling applications where rebar encounters are likely.
