The Diablo AMPED Rebar Demon SDS-Max 4-Cutter Full Carbide Head Dust Extraction Hammer Drill Bit (1 1/8" diameter, 26" overall length, 16" working length) is engineered to transform reinforced concrete drilling by combining ultra-fast hole boring with a patented dust extraction system - delivering clean, anchor-ready holes in just two steps instead of the traditional five. Designed for use with SDS-Max rotary hammer drills, this professional-grade concrete drill bit powers through reinforced concrete, rebar, stone, brick, and block with remarkable speed and durability, while simultaneously removing up to 97% of dust and debris to protect workers from airborne silica and eliminate time-consuming cleanup between holes.

Key Features

• Dura-Carbide Full Carbide Head rated to 1800 deg. Fahrenheit - withstands more than twice the heat tolerance of standard bits (which fail at 800 deg. Fahrenheit), so the cutting head stays intact and effective even during aggressive drilling through rebar and hard concrete.
• Impact-Resistant 4-Cutter Tungsten Full Carbide Head - takes smaller, controlled bites of rebar rather than full-force impacts, delivering reduced vibration, consistent carbide wear, and a lifespan up to 7X longer than standard two-cutter bits - meaning one AMPED Rebar Demon replaces up to seven conventional bits.
• Tri-Metal Fusion Welding with up to 3X stronger weld - keeps the full carbide head securely bonded during extreme rebar impacts, preventing head breakage and protecting the investment in both the bit and the work surface.
• Patented two-step dust extraction system removing up to 97% of dust particles - eliminates the traditional "Blow-Brush-Blow" cleaning method entirely, allowing epoxy and anchor placement immediately after drilling for up to 66% labor savings and a safer, healthier job site environment indoors and outdoors.
• Removable stainless-steel dust sleeve paired with the Snap-Lock Adapter (sold separately) - connects to most common vacuum cleaner attachments to capture concrete dust and silica at the source, reducing airborne particles and meeting clean-air requirements without additional equipment changes.
• Drill-to-Fill process streamlined from five steps down to two - drilling and dust extraction happen simultaneously, accelerating hole preparation by up to 3X compared to standard methods and eliminating the need for separate rebar cutters.
• Precision Tip with sharp 90 deg. pyramid-shaped design - provides the stability and accuracy needed for fast, precise hole placement in reinforced concrete, while a visible wear mark confirms that drilling diameter remains accurate throughout the bit's life.
• Potential savings of up to $200 per SDS-Max bit - by replacing up to seven 2-cutter bits with a single AMPED Rebar Demon bit, crews reduce downtime for bit changes and lower total tooling costs significantly on large anchor-setting or post-installed fastener projects.
• Compatible with SDS-Max rotary hammer drills - the SDS-Max shank provides secure, tool-free bit insertion and delivers full rotary hammer energy transfer for maximum productivity in demanding concrete and masonry drilling applications.

Why This Product

• Crews drilling anchor holes in reinforced concrete no longer need to stop and run rebar cutters, blow out holes, brush debris, or blow again before placing epoxy - the AMPED Rebar Demon's two-step Drill-to-Fill process handles rebar and dust extraction simultaneously, cutting hole preparation time by up to 3X and saving up to 66% in labor costs.
• On job sites with silica dust exposure requirements - whether interior, overhead, or exterior work - the patented stainless-steel sleeve and Snap-Lock vacuum adapter system captures up to 97% of dust at the source, reducing airborne silica without relying on respirators alone and contributing to a cleaner, safer working environment.
• For contractors managing bit costs on high-volume drilling projects, the Dura-Carbide 4-cutter head's up to 7X longer service life versus standard 2-cutter bits means transitioning from seven conventional bits to just one AMPED Rebar Demon bit per hole series - delivering potential savings of up to $200 per SDS-Max bit and significantly reducing tool changeover time.
• When anchor accuracy is critical, the 90 deg. Precision Tip provides drilling stability from the first contact, and the built-in visible wear mark serves as a continuous quality check that the 1 1/8" bore diameter is being maintained - ensuring anchors and epoxy systems seat correctly every time.

Frequently Asked Questions

Does this drill bit require a special adapter to connect to a vacuum for dust extraction?

Yes. The Snap-Lock Adapter, which is sold separately and is available in both SDS-Plus and SDS-Max versions, is required to connect the AMPED Rebar Demon Dust Extraction Hammer Drill Bit to a vacuum cleaner. The removable stainless-steel dust sleeve on the bit works together with the Snap-Lock Adapter to capture and extract up to 97% of dust and debris. The universal Snap-Lock Adapter fits most common vacuum cleaner attachments.

How does this bit handle rebar without breaking or wearing out prematurely?

The 4-cutter tungsten full carbide head is engineered to take small, controlled bites of rebar rather than absorbing full blunt impacts. This approach delivers controlled, consistent carbide wear and reduced vibration. The Dura-Carbide material withstands up to 1800 deg. Fahrenheit of heat - compared to standard bits that fail at 800 deg. Fahrenheit - and the full carbide head is secured with Tri-Metal Fusion Welding that is up to 3X stronger to prevent head breakage during extreme rebar impacts. The result is a lifespan up to 7X longer than standard two-cutter bits.

Can this bit replace my current workflow that uses separate rebar cutters and blow-out procedures before setting anchors?

Yes. The AMPED Rebar Demon's two-step Drill-to-Fill system is specifically designed to eliminate the traditional five-step "Blow-Brush-Blow" process and the need for separate rebar cutters. Drilling and dust extraction happen at the same time, producing a clean hole that is ready for immediate epoxy and anchor placement. This reduces hole preparation time by up to 3X and can deliver labor savings of up to 66% compared to current standard methods.

How do I know when the bit's drilling diameter is no longer accurate?

The AMPED Rebar Demon includes a visible wear mark on the bit body. This indicator allows users to monitor the condition of the bit and confirms whether the 1 1/8" drilling diameter is still being maintained accurately, ensuring that anchors and epoxy systems will seat correctly and that hole quality meets specification requirements throughout the bit's service life.
