The Diablo AMPED Rebar Demon SDS-Max 4-Cutter Full Carbide Head Dust Extraction Hammer Drill Bit redefines productivity in reinforced concrete drilling with a revolutionary two-step Drill-to-Fill system that simultaneously drills and extracts up to 97% of dust and debris. Engineered for SDS-Max rotary hammer drills, this 7/8 in. x 26 in. bit features a 16 in. working length and a full carbide head built with Diablo's exclusive Dura-Carbide - capable of withstanding up to 1800 deg. Fahrenheit of intense heat, far exceeding the 800 deg. Fahrenheit threshold where standard bits fail. Whether you're setting anchors in reinforced concrete, drilling through stone, or working in brick and block, this bit delivers ultra-clean, dust-free holes and a safer working environment in a fraction of the time required by conventional methods.

Key Features

• Dura-Carbide Full Carbide Head withstands up to 1800 deg. Fahrenheit - resists the extreme heat generated by rebar contact, delivering controlled carbide wear and a lifespan of up to 7X longer than standard two-cutter bits, reducing the number of bits needed per job and cutting tool costs significantly.
• Impact-Resistant 4-Cutter Tungsten Full Carbide Head - takes smaller, more precise bites of rebar to deliver controlled, consistent carbide wear and reduced vibration, producing fast, accurate holes in reinforced concrete without the need for separate rebar cutters.
• Tri-Metal Fusion Welding with up to 3X stronger weld - keeps the full carbide head intact during extreme rebar impacts, preventing head breakage and extending reliable performance in high-stress hammer drill applications.
• Patented dust extraction system removes up to 97% of dust particles - the removable stainless-steel sleeve channels dust away from the hole during drilling, creating clean anchor-ready holes immediately and dramatically reducing airborne silica dust for a safer indoor or outdoor work environment.
• Two-step Drill-to-Fill system replaces the five-step "Blow-Brush-Blow" cleaning method - streamlines hole preparation by up to 3X faster than current methods, delivering labor savings of up to 66% and enabling immediate epoxy and anchor placement.
• Compact Snap-Lock Adapter compatibility (sold separately) - connects the bit directly to most common vacuum cleaner attachments via a universal fit, allowing quick and easy exchange of different bit sizes without sacrificing suction performance.
• Precision Tip with sharp 90 deg. pyramid shaped design - delivers the stability and accuracy needed to start holes exactly where required in reinforced concrete, reducing bit walk and improving hole placement for anchor setting.
• Visible wear mark on the bit body - assures that the drilling diameter remains accurate throughout the life of the bit, giving operators a clear indicator when performance is approaching its limit.
• Produced in Germany with SDS-Max shank - compatible with SDS-Max rotary hammer drills and designed for demanding jobsite conditions including overhead drilling, interior, and exterior reinforced concrete applications.
• Up to 2X more carbide than standard bits - the Dura-Carbide composition provides greater material volume to absorb rebar impacts and prolonged heat exposure, transitioning users from 7 standard two-cutter bits down to just 1 AMPED Rebar Demon bit per application, for potential savings of up to $200 per SDS-Max bit.

Why This Product

• Eliminates multi-step hole cleaning entirely - by combining drilling and dust extraction into a single two-step process, this bit removes the need for blowing, brushing, and re-blowing holes before anchor placement, cutting labor time by up to 66% on concrete anchor jobs.
• Purpose-built to handle rebar without stopping - the 4-cutter full carbide head is specifically engineered to pass through rebar by taking controlled small bites rather than shattering or stalling, making it the right choice for reinforced concrete slabs, foundations, and structural elements where rebar is unavoidable.
• Reduces airborne silica dust exposure - the patented vacuum-assisted extraction system captures up to 97% of silica-bearing dust particles at the source, supporting a healthier working environment for crews drilling indoors or in enclosed spaces where dust accumulation poses a serious hazard.
• Dramatically lowers total cost per hole - the combination of up to 7X longer bit life and elimination of rebar cutters, cleaning tools, and multi-step preparation steps means one AMPED Rebar Demon bit replaces up to 7 conventional bits, making it a cost-effective upgrade for contractors who drill frequently in reinforced concrete.

Frequently Asked Questions

Does the Snap-Lock Adapter come included with this bit?

No. The Snap-Lock Adapter is sold separately. It is available in two versions - one for SDS-Plus and one for SDS-Max - and connects the AMPED Rebar Demon Dust Extraction bit to most common vacuum cleaner attachments for maximum dust and debris extraction.

How does the two-step dust extraction process work?

The removable stainless-steel sleeve surrounding the bit channels dust and debris away from the hole as drilling occurs. When connected to a vacuum via the Snap-Lock Adapter (sold separately), the system captures up to 97% of dust particles generated during drilling. This replaces the traditional five-step "Blow-Brush-Blow" cleaning process, allowing epoxy and anchor placement immediately after drilling without any additional hole preparation.

Can this bit drill through rebar without additional tools?

Yes. The 4-cutter tungsten full carbide head is specifically designed to drill through rebar by taking smaller, controlled bites. This eliminates the need for separate rebar cutters and allows continuous drilling through reinforced concrete. The Dura-Carbide composition withstands up to 1800 deg. Fahrenheit of heat generated during rebar contact, compared to the 800 deg. Fahrenheit failure point of standard bits.

How much longer does the AMPED Rebar Demon bit last compared to a standard two-cutter bit?

The AMPED Rebar Demon 4-Cutter Full Carbide Head delivers up to 7X longer life than standard two-cutter bits. In practical terms, this means one AMPED Rebar Demon SDS-Max bit can replace up to 7 conventional two-cutter bits, resulting in potential savings of up to $200 per SDS-Max bit over the course of a project.
