Diablo 1/4" x 6" x 8" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit by Diablo delivers one of the fastest and longest-lasting drilling solutions available for concrete and masonry work. Engineered in Germany with Diablo's proprietary Dura-Carbide formula, this SDS-Plus rotary hammer bit is built to withstand the punishing impact and high-heat conditions of heavy-duty anchor hole drilling, giving professionals a reliable edge on the job site.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat applications - dramatically extending service life compared to standard hammer drill bits so you replace bits less often and keep work moving
• Peak Point Tip design for aggressive starts that produce clean, fast holes - allows you to begin drilling immediately without wandering, reducing layout time and rework
• Optimized brazing and hardening process extends life of carbide tips and increases productivity - the carbide bond is strengthened at the manufacturing level so tips stay sharp and secure through demanding concrete and brick drilling cycles
• Optimized four-flute design removes dust faster, keeping the carbide tips cooler for ultimate strength and durability - faster dust evacuation means less friction heat buildup, protecting tip integrity and prolonging cutting performance
• SDS-Plus shank - locks securely into SDS-Plus rotary hammers for consistent torque transfer and easy, tool-free bit changes
• 2-cutter carbide head - provides balanced cutting action through concrete and brick/block for straight, accurate holes

Why This Product

• The Dura-Carbide formula and optimized hardening process mean this bit stays productive through applications where standard carbide tips would wear prematurely - a practical advantage when drilling multiple anchor holes in concrete or masonry
• The Peak Point Tip starts aggressively without skating across the surface, making it a dependable choice for precise anchor placement in concrete and brick/block without the need for a center punch
• The four-flute dust-removal design keeps the cutting tip cooler during extended drilling sessions, reducing the risk of tip degradation and helping maintain hole quality from the first hole to the last
• At 1/4" diameter with a 6" working length and 8" overall length, this bit is sized for common anchor hole applications in concrete and masonry where reach into deeper substrates is required

Frequently Asked Questions

What type of drill is required to use this hammer drill bit?

This bit requires an SDS-Plus rotary hammer drill. The SDS-Plus shank design locks into compatible rotary hammers for secure, tool-free bit changes and efficient hammer drilling action.

What materials can this bit drill through?

This carbide-tipped hammer drill bit is designed for use in concrete and brick/block masonry applications. It is not intended for wood, metal, or other non-masonry materials.

What is the difference between the overall length and the working length?

The overall length of this bit is 8", which includes the SDS-Plus shank. The working length - the portion of the bit that actively cuts into the material - is 6". This distinction is important when determining how deep a hole you can drill in a given application.

What makes Dura-Carbide different from standard carbide on hammer drill bits?

Diablo's Dura-Carbide is formulated to withstand both heavy impact forces and high heat generated during hammer drilling. Combined with Diablo's optimized brazing and hardening process, the carbide tips resist wear and stay bonded longer than standard carbide, extending the usable life of the bit and maintaining cutting performance through demanding concrete drilling applications.
