Diablo SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bits deliver one of the fastest and longest lasting drilling solutions available for concrete and masonry applications. Engineered with Diablo's proprietary Dura-Carbide technology and a unique brazing and hardening process, these 5/16 in. x 8 in. bits are built to outlast standard hammer bits while maintaining speed and accuracy in demanding rotary hammer work. Whether you are anchoring into concrete or drilling through brick and block, this SDS Plus bit provides the aggressive performance and clean hole quality professionals depend on.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat applications - dramatically extends working life versus standard hammer drill bits, reducing the need for frequent bit replacement on the job
• Peak Point Tip design for aggressive starts - produces clean, fast holes suited for common sized anchors, minimizing wander and improving accuracy from the first contact
• Optimized brazing and hardening process extends life of carbide tips and increases productivity - the securely bonded tips hold up under repeated hammer action, maintaining cutting performance longer
• Optimized four-flute design removes dust faster - keeps the carbide tips cooler for ultimate strength and durability, reducing heat buildup that can shorten bit life during extended concrete drilling
• 5/16 in. diameter with 6 in. working length and 8 in. overall length - sized for common anchor hole requirements with enough reach for deeper embedment applications
• SDS Plus shank - compatible with corded and cordless SDS Plus rotary hammer drills for maximum versatility across job site tool setups

Why This Product

• The Dura-Carbide tips and optimized brazing process mean fewer bit changes and more holes per bit - a practical advantage when drilling multiple anchor points in concrete or brick over a full workday.
• The Peak Point Tip geometry produces clean, fast holes for common sized anchors - making this bit a reliable choice when hole quality directly affects anchor performance and load ratings.
• The four-flute dust removal design keeps the bit running cooler during continuous use - extending service life in high-demand concrete drilling without sacrificing cutting speed.
• Optimized for both corded and cordless SDS Plus rotary hammers - this bit adapts to the tools already on your job site without requiring additional adapters or hardware.

Frequently Asked Questions

What type of rotary hammer is this bit compatible with?

This bit is compatible with corded and cordless SDS Plus rotary hammer drills. The SDS Plus shank design allows it to seat securely in any standard SDS Plus chuck without additional adapters.

What materials can this hammer drill bit cut through?

This bit is designed for use in concrete and brick/block masonry. The Dura-Carbide tips are engineered to withstand the impact and heat generated when drilling into these hard, abrasive materials.

What makes the Peak Point Tip design beneficial for anchor installation?

The Peak Point Tip allows for aggressive starts that produce clean, fast holes suited for common sized anchors. This helps prevent bit walking at the start of a hole and results in a more precise, cleaner bore - which is important when hole diameter and cleanliness affect anchor holding strength.

How does the four-flute design help during extended concrete drilling?

The optimized four-flute design removes dust from the hole more efficiently than fewer-flute designs, which keeps the carbide tips cooler during use. Cooler operating temperatures help maintain the ultimate strength and durability of the bit, contributing to a longer working life in demanding applications.
