The Diablo 1/2 in. x 4 in. x 6 in. SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered for professionals and serious contractors who need fast, clean holes in concrete, brick, and block. Built with Diablo's proprietary Dura-Carbide formulation and a four-flute dust-removal design, this 1/2 in. rotary hammer bit delivers the speed and longevity that demanding masonry drilling applications require. Whether you are setting anchors in poured concrete or drilling through CMU block, this SDS-Plus bit is optimized for both corded and cordless SDS-Plus rotary hammers, giving you reliable performance across a wide range of jobsite conditions.

Key Features

• Diablo Dura-Carbide construction - withstands heavy impact and high-heat drilling conditions, dramatically extending service life compared to standard hammer drill bits so you replace bits less often and spend more time drilling
• Peak Point Tip design - enables aggressive, on-target starts that produce clean, fast holes sized correctly for common anchors, reducing the need for touch-up work or repositioning
• Optimized brazing and hardening process - extends the life of the carbide tips and increases overall productivity, meaning more holes per bit before performance degrades
• Optimized four-flute design - evacuates dust from the hole faster than conventional flutes, keeping carbide tips cooler during extended use for ultimate strength and durability
• SDS-Plus shank interface - locks securely into any SDS-Plus rotary hammer, providing consistent torque transfer and quick bit changes on corded or cordless tools
• 4 in. working length in a 6 in. overall length - gives you adequate reach for typical anchor-depth applications while keeping the bit compact and easy to handle
• Made in Germany - produced to tight manufacturing tolerances for dimensional accuracy, ensuring holes meet the sizing requirements of standard concrete anchors

Why This Product

• If you are drilling anchor holes in concrete or brick and need consistent hole quality, the Peak Point Tip design starts on contact without wandering, delivering clean-edged holes that anchor hardware seats into correctly every time.
• For users who burn through standard carbide bits quickly on heavy rotary hammer work, the Dura-Carbide formula and enhanced brazing process directly address short bit life - offering a longer-lasting alternative that holds up to impact and heat on the jobsite.
• The four-flute dust-evacuation geometry keeps the cutting tip cooler during continuous drilling, which translates to fewer stops to let the bit cool and a more efficient workflow when drilling multiple holes.
• Compatibility with both corded and cordless SDS-Plus rotary hammers makes this bit a flexible choice for crews moving between plug-in and battery-powered tools on the same project.

Frequently Asked Questions

What materials can this SDS-Plus bit drill through?

This bit is rated for use in concrete and brick/block. The Dura-Carbide tip and Peak Point Tip design are specifically optimized to cut through these masonry materials cleanly and quickly.

Will this bit work with my cordless SDS-Plus rotary hammer?

Yes. This bit is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers. As long as your tool uses an SDS-Plus chuck interface, this bit is compatible.

What is the working length versus the overall length of this bit?

The bit has a 6 in. overall length with a 4 in. working length. The working length is the portion of the bit that actively cuts into the material, making it suitable for drilling anchor-depth holes in typical concrete applications.

How does the four-flute design benefit drilling performance?

The optimized four-flute design removes dust from the hole faster than a standard two-flute bit. This faster dust evacuation keeps the carbide tips cooler during use, which preserves tip strength and durability and helps you maintain drilling speed over extended sessions.
