The Diablo Rebar Demon SDS-Plus Full Carbide Head Concrete Anchor Hammer Drill Bit is a precision-engineered 3/16 in. x 6 in. rotary hammer bit built for fast, accurate anchor-setting holes in concrete and brick or block. Designed to handle the rigors of high-powered SDS-Plus rotary hammers - both corded and cordless - this bit combines a full-carbide head with Diablo's proprietary Tri-Metal Diffusion Bonding technology to deliver extreme heat resistance, breakage prevention, and long service life. Whether you are installing Tapcon fasteners or setting anchors in rebar-reinforced slabs, this bit provides the stability, speed, and durability that demanding jobsite conditions require.

Key Features

• Full-Carbide Head with Tri-Metal Diffusion Bonding - resists high heat and prevents breakage during aggressive hammer drilling, dramatically extending bit life compared to standard hammer bits
• Diablo-made carbide construction - withstands the stress of high-powered rotary hammers and rebar impact, keeping the bit performing longer before replacement is needed
• Precision Tip geometry - delivers stability and accuracy from the moment drilling begins, producing fast, precise holes required for reliable anchor setting
• Optimized four-flute design - removes dust faster from the bore hole, keeping the carbide head cooler under load for sustained strength and durability
• Hex collar compatible with anchor drive sleeve - streamlines the Tapcon and anchor installation workflow, reducing the number of bit changes needed on the job
• Optimized for corded and cordless SDS-Plus rotary hammers - delivers maximum performance across a wide range of tool platforms commonly used in concrete and masonry work
• 3/16 in. diameter with 3-1/2 in. working length - sized specifically for common anchor and Tapcon hole requirements in concrete and block applications

Why This Product

• For contractors setting anchors in rebar-reinforced concrete, the full-carbide head and Tri-Metal Diffusion Bonding mean the bit survives rebar strikes that would crack or break a standard carbide-tipped bit - reducing downtime and replacement costs.
• The hex collar design makes this bit directly compatible with an anchor drive sleeve, so the same tool can drill the pilot hole and drive the fastener without swapping accessories - a real time saver when setting multiple Tapcon anchors.
• The four-flute dust-removal design actively keeps the cutting head cooler during extended use, which translates to consistent hole quality and a longer useful life per bit - important when drilling many holes in a single session.
• Engineered to perform in both corded rotary hammers and cordless SDS-Plus tools, this bit fits naturally into jobsite workflows without requiring a specific tool type, giving crews more flexibility across different concrete and masonry tasks.

Frequently Asked Questions

What type of rotary hammer is this bit compatible with?

This bit is designed for SDS-Plus rotary hammer drills - both corded and cordless models. It is optimized to deliver maximum performance across SDS-Plus tool platforms commonly used in concrete and masonry drilling.

What makes the full-carbide head more durable than a standard hammer drill bit?

The full-carbide head is produced using Tri-Metal Diffusion Bonding technology, which provides heat resistance and prevents breakage during high-impact drilling. Diablo-made carbide also withstands impact and high-heat conditions that would degrade a standard carbide-tipped bit much faster, dramatically extending usable life.

What is the hex collar on this bit used for?

The hex collar is compatible with an anchor drive sleeve, allowing the bit to be used in conjunction with anchor installation tools. This makes it easier to drill the pilot hole and set anchors like Tapcon fasteners without needing to change accessories between steps.

What materials can this bit drill through?

This bit is rated for use in concrete and brick or block. The full-carbide head and four-flute design are engineered to handle the hard, abrasive nature of these masonry materials, including concrete with rebar present.
