Diablo AMPED Rebar Demon SDS-Max 4-Cutter Full Carbide Head Dust Extraction Hammer Drill Bit (1-1/4 in. x 16 in. x 26 in.) is engineered to transform concrete drilling productivity by combining a patented dust extraction system with an impact-resistant full carbide head - delivering clean, anchor-ready holes in reinforced concrete and standard concrete in just two steps. Designed for use with SDS-Max rotary hammer drills, this bit eliminates the traditional five-step "Blow-Brush-Blow" hole preparation method, saving up to 66% in labor and dramatically reducing airborne silica dust exposure on both interior and exterior job sites.

Key Features

• Dura-Carbide Full Carbide Head withstands up to 1800 deg. Fahrenheit - standard bits fail at 800 deg. Fahrenheit, meaning this bit stays effective through intense rebar hits and high-powered hammer drill stress that would destroy conventional two-cutter bits.
• Impact-Resistant 4-Cutter Tungsten Full Carbide Head - takes smaller, controlled bites of rebar to deliver consistent carbide wear, reduced vibration, and up to 7X longer life versus standard two-cutter bits, reducing the number of bits you need to purchase per job.
• Tri-Metal Fusion Welding with up to 3X stronger weld - keeps the full carbide head intact during extreme rebar impact, preventing breakage and ensuring the bit holds together under the harshest drilling conditions.
• Patented dust extraction system removes up to 97% of dust and debris - creates clean, anchor-ready holes immediately after drilling without the need for additional cleaning steps, allowing epoxy and anchor placement to begin right away.
• Removable stainless-steel dust sleeve paired with the Snap-Lock Adapter (sold separately) - creates the first-ever 4-cutter full carbide head two-step clean hole dust extraction system, connecting the bit to most common vacuum cleaner attachments for maximum airborne silica dust reduction.
• Drill-to-Fill two-step process replaces a five-step workflow - speeds up the hole drilling process by up to 3X compared to standard bits and eliminates the need for separate rebar cutters, delivering up to 66% labor savings and potential cost savings of up to $200 per SDS-Max bit.
• Precision Tip with sharp 90 deg. pyramid shape - provides the stability and accuracy required to start fast, precise holes in reinforced concrete, while a visible wear mark assures drilling diameter accuracy throughout the bit's life.
• 2X more carbide than standard bits - the Dura-Carbide composition means more material available to withstand rebar hits and thermal stress, directly extending the usable life of the bit on demanding concrete and masonry applications.
• Compatible with SDS-Max rotary hammer drills - the SDS-Max shank delivers secure, tool-free bit retention in compatible hammers, maintaining reliable energy transfer for fast drilling in reinforced concrete, concrete, stone, brick, and block.
• Reduction of airborne silica dust during drilling - helps create a safer, healthier working environment whether drilling indoors, overhead, or on exterior job sites, supporting compliance with silica dust exposure safety practices.

Why This Product

• For contractors drilling anchor holes in reinforced concrete, this bit replaces up to seven 2-cutter bits with a single AMPED Rebar Demon bit - cutting spend on bits and reducing job site downtime from frequent bit changes.
• The integrated dust extraction system eliminates the need for the "Blow-Brush-Blow" cleaning method and separate rebar cutters, compressing a five-step process down to two steps and delivering up to 3X faster hole preparation for anchor setting and epoxy placement.
• The Dura-Carbide head withstands up to 1800 deg. Fahrenheit - more than double the 800 deg. Fahrenheit threshold of standard bits - making this bit suited for high-powered hammer drills and rebar-heavy concrete without premature failure.
• The removable stainless-steel sleeve and universal Snap-Lock Adapter (sold separately) allow fast bit-size changes and connection to most common vacuum attachments, giving this dust extraction system broad compatibility across job sites where silica dust reduction is a priority.

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, but the Snap-Lock Adapter - which connects the bit to a vacuum for full dust extraction - is sold separately. Two versions of the Snap-Lock Adapter are available: one for SDS-Plus and one for SDS-Max. The universal Snap-Lock Adapter is compatible with most common vacuum cleaner attachments.

How does the 4-cutter full carbide head handle rebar encountered during drilling?

The impact-resistant 4-Cutter Tungsten Full Carbide Head is specifically designed to take small, controlled bites of rebar rather than forcing through it in a single aggressive cut. This approach delivers consistent carbide wear, reduced vibration, and a lifespan of up to 7X longer than standard two-cutter bits. Tri-Metal Fusion Welding with up to 3X stronger weld keeps the carbide head intact during extreme rebar impact situations.

What is the working length versus the total length of this bit, and why does it matter?

This bit has a total length of 26 in. and a working length of 16 in. The working length is the fluted section that actually drills and extracts debris from the hole. A 16 in. working length allows deep anchor holes in thick reinforced concrete slabs and walls while the overall 26 in. length provides the reach needed for overhead and extended-depth drilling applications.

How much faster is hole preparation compared to traditional drilling methods?

The AMPED Rebar Demon dust extraction system streamlines the hole drilling process from five steps down to two steps, delivering up to 3X faster hole preparation compared to standard bits and the traditional "Blow-Brush-Blow" cleaning method. This two-step Drill-to-Fill approach means epoxy and anchor placement can be accomplished immediately after drilling, resulting in up to 66% labor savings per hole.
