Diablo AMPED Rebar Demon SDS-Max 4-Cutter Full Carbide Head Dust Extraction Hammer Drill Bit delivers a complete concrete drilling and hole preparation solution built for professionals tackling reinforced concrete, stone, brick, and block. Engineered with a full tungsten carbide head, patented dust extraction technology, and Diablo's exclusive Dura-Carbide composition, this 1 in. x 16 in. x 26 in. SDS-Max rotary hammer drill bit streamlines the entire process - from drilling through rebar-laden concrete to producing clean, anchor-ready holes - in just two steps rather than the traditional five. Whether used for anchor setting in reinforced slabs, overhead drilling, or exterior structural applications, this bit represents a dramatic leap in drilling speed, dust control, and bit longevity.

Key Features

• 4-Cutter Full Tungsten Carbide Head - takes smaller, controlled bites of rebar rather than brute-force contact, resulting in reduced vibration, consistent carbide wear, and a bit lifespan up to 7X longer than standard two-cutter bits, which means fewer bit changes and less downtime on the job.
• Dura-Carbide Composition with up to 2X More Carbide - withstands up to 1800 deg. Fahrenheit of intense heat versus standard bits that fail at 800 deg. Fahrenheit, so the cutting head remains intact and functional even during the most demanding rebar encounters.
• Tri-Metal Fusion Welding - bonds the full carbide head with up to 3X stronger welds to resist breakage during extreme impact situations such as rebar hits, giving users confidence that the head stays secure throughout the life of the bit.
• Patented Dust Extraction System with Removable Stainless-Steel Sleeve - captures up to 97% of dust and debris generated during drilling, eliminating airborne silica dust and producing clean holes ready for immediate epoxy and anchor placement without the traditional "Blow-Brush-Blow" cleaning cycle.
• Two-Step Drill-to-Fill Process - simultaneously drills and extracts dust debris, reducing hole preparation from five steps down to two and delivering drilling speeds up to 3X faster than standard methods, translating directly into up to 66% labor savings per hole.
• Compatible Snap-Lock Adapter (sold separately) - connects the bit to most common vacuum cleaner attachments for maximum dust and debris extraction and allows quick, easy bit size exchanges without complicated setup, keeping the workflow moving.
• Precision Tip with 90 deg. Pyramid Shape - provides stability and accuracy from the moment drilling begins, enabling fast, precise hole placement in reinforced concrete for anchor setting where location accuracy is critical.
• Visible Wear Mark - indicates and assures the accuracy of the drilling diameter throughout the life of the bit, so users always know the hole produced meets spec without guesswork.
• SDS-Max Shank - designed for use with SDS-Max rotary hammer drills, ensuring secure bit retention and maximum energy transfer during high-powered hammer drilling.
• Cost-Saving Bit Economics - transitioning from seven standard two-cutter bits to one AMPED Rebar Demon bit delivers potential savings of up to $200 per SDS-Max bit by extending bit life dramatically and eliminating the need for separate rebar cutters.

Why This Product

• For contractors drilling into reinforced concrete, this bit eliminates both the rebar cutter and the "Blow-Brush-Blow" hole cleaning method in a single tool - cutting the hole preparation process from five steps to two and saving up to 66% in labor costs per hole.
• The combination of the removable stainless-steel dust sleeve and the Snap-Lock Adapter (sold separately) creates the first 4-cutter full carbide head two-step clean hole dust extraction system, capturing up to 97% of airborne silica dust - a critical safety advantage for indoor, overhead, and enclosed-space drilling environments.
• At up to 7X longer life than standard two-cutter bits and the ability to handle rebar directly without a separate cutting step, this bit reduces total bit consumption, lowering material costs by up to $200 per SDS-Max bit compared to running multiple conventional bits through the same application.
• The full carbide head's heat resistance up to 1800 deg. Fahrenheit - more than double the threshold of standard bits - means the bit maintains performance through repeated rebar encounters and high-powered hammer drill stress without head failure or premature wear.

Frequently Asked Questions

Does this bit require a separate rebar cutter to drill through reinforced concrete?

No. The 4-cutter full tungsten carbide head is specifically designed to drill directly through rebar in reinforced concrete without a separate rebar cutter. It takes smaller, controlled bites of rebar to manage carbide wear, reduce vibration, and maintain bit integrity, making rebar cutters obsolete for this application.

What vacuum or dust extraction equipment is needed to use the dust extraction feature?

The dust extraction system requires the Snap-Lock Adapter, which is sold separately (available in both SDS-Max and SDS-Plus versions). The compact Snap-Lock Adapter connects the AMPED Rebar Demon bit to most common vacuum cleaner attachments, enabling the full two-step dust extraction process that captures up to 97% of dust and debris.

Can holes drilled with this bit be used immediately for epoxy and anchor placement?

Yes. Because the patented dust extraction system removes up to 97% of dust and debris during drilling, holes are clean and ready for immediate epoxy and anchor placement upon completion, eliminating the traditional "Blow-Brush-Blow" cleaning method entirely and reducing hole preparation to just two steps.

How much longer does this bit last compared to standard hammer drill bits?

The AMPED Rebar Demon 4-Cutter Full Carbide Head delivers up to 7X longer life than standard two-cutter bits. Diablo's Dura-Carbide composition - featuring up to 2X more carbide and heat resistance up to 1800 deg. Fahrenheit versus the 800 deg. Fahrenheit threshold where standard bits fail - combined with Tri-Metal Fusion Welding and controlled rebar engagement, enables the transition from seven conventional bits to just one AMPED Rebar Demon bit for equivalent work output.
