The Diablo AMPED Rebar Demon SDS-Max 4-Cutter Full Carbide Head Dust Extraction Hammer Drill Bit is engineered for professionals who demand maximum productivity when drilling into reinforced concrete, concrete, stone, brick/block, and rebar. Measuring 7/8 in. in diameter with an 18 in. overall length and an 8 in. working length, this SDS-Max shank bit redefines what a hammer drill bit can accomplish - combining a full carbide head, a built-in dust extraction system, and extreme heat resistance into a single, field-proven tool. Designed and built to tackle the most demanding anchor-setting and concrete drilling applications, it reduces the traditional five-step hole preparation process down to just two steps, delivering up to 66% in labor savings and dramatically faster epoxy and anchor placement.

Key Features

• 4-Cutter Tungsten Full Carbide Head - takes smaller, controlled bites of rebar to reduce vibration and deliver consistent boring through reinforced concrete, extending bit life up to 7X longer than standard two-cutter bits and reducing the number of replacement bits needed on the job.
• Dura-Carbide Composition - features up to 2X more carbide and withstands up to 1800 deg. Fahrenheit of intense heat, versus standard bits that fail at 800 deg. Fahrenheit, keeping the bit performing reliably even after repeated rebar contact.
• Tri-Metal Fusion Welding - creates a weld up to 3X stronger than conventional methods to keep the full carbide head intact during extreme impact situations such as rebar strikes, preventing breakage and costly downtime.
• Patented Dust Extraction System with Removable Stainless-Steel Sleeve - captures up to 97% of dust particles and debris generated during drilling, producing clean holes ready for immediate epoxy and anchor placement while reducing airborne silica dust for a safer working environment indoors and outdoors.
• Two-Step Drill-to-Fill Process - eliminates the traditional "Blow-Brush-Blow" cleaning method and removes the need for separate rebar cutters, accelerating hole preparation up to 3X faster than current methods for significant labor and cost savings.
• Precision Tip with 90 deg. Pyramid Shape - delivers stability and accuracy at the start of each hole, producing fast, precise bores in reinforced concrete for reliable anchor setting without wandering or walking.
• Visible Wear Mark - indicates when the drilling diameter accuracy has been reached, giving users a clear, measurable signal to maintain quality and consistency across every hole.
• Compatible with Snap-Lock Adapter (sold separately) - connects the bit to most common vacuum cleaner attachments for maximum dust and debris extraction, and allows quick and easy exchange between different drill bit sizes in the field.
• Saves up to $200 per SDS-Max Bit - by replacing up to 7 standard two-cutter bits with a single AMPED Rebar Demon bit, users can significantly reduce spend on consumables across a project.
• SDS-Max Shank - engineered for use with SDS-Max rotary hammer drills, ensuring secure bit retention and efficient energy transfer during high-powered concrete drilling.

Why This Product

• For contractors setting anchors in reinforced concrete, this bit eliminates the need for separate rebar cutters and multi-step hole cleaning - condensing the workflow into just two steps and saving up to 66% in labor costs compared to traditional methods.
• The full carbide head's ability to withstand up to 1800 deg. Fahrenheit - more than double the heat tolerance of standard bits - means fewer bit failures during rebar-heavy drilling, so work continues without costly interruptions or replacements.
• The integrated dust extraction system removes up to 97% of airborne dust and debris at the source, helping crews meet jobsite air quality requirements and reducing silica dust exposure whether working indoors or overhead.
• A single AMPED Rebar Demon SDS-Max bit can replace up to 7 standard two-cutter bits, translating directly into lower consumable costs and fewer tool changes on long drilling runs in concrete and masonry applications.

Frequently Asked Questions

Does this bit require a separate vacuum or adapter to use the dust extraction system?

Yes. The removable stainless-steel sleeve is included with the bit and works as part of the dust extraction system, but the Snap-Lock Adapter - which connects the bit to a vacuum for maximum dust and debris extraction - is sold separately. The Snap-Lock Adapter is available in two versions: one for SDS-Plus and one for SDS-Max. The universal Snap-Lock Adapter fits most common vacuum cleaner attachments.

How does the AMPED Rebar Demon handle rebar encountered during drilling?

The 4-cutter tungsten full carbide head is specifically designed to take smaller, controlled bites of rebar rather than attempting to cut through it in one aggressive pass. This approach delivers controlled carbide wear, reduced vibration, and precise boring. The Dura-Carbide composition withstands up to 1800 deg. Fahrenheit of heat - far beyond the 800 deg. Fahrenheit threshold where standard bits fail - and Tri-Metal Fusion Welding keeps the head intact under extreme rebar impact.

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

The AMPED Rebar Demon's 4-cutter full carbide head delivers a bit lifespan up to 7X longer than standard two-cutter bits. In practice, this means that a single AMPED Rebar Demon SDS-Max bit can replace up to 7 conventional bits, resulting in potential savings of up to $200 per SDS-Max bit spent on consumables.

What does the visible wear mark on this bit indicate?

The visible wear mark is a built-in reference point that indicates when the drilling diameter accuracy has been reached. It gives users a clear, reliable signal to verify that each hole is being drilled to the correct diameter - helping maintain consistency and quality across multiple holes during anchor-setting operations.
