The Diablo 1/4" x 4" x 6" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit delivers one of the fastest and longest lasting drilling solutions available for concrete and masonry work. Built by Diablo and engineered in Germany, this rotary hammer bit combines Dura-Carbide construction with a precision Peak Point tip to give tradespeople and contractors a reliable tool for setting common anchors in concrete and block. Whether you are running a corded rotary hammer on a job site or a cordless SDS-Plus drill in tight spaces, this 1/4 in. bit is optimized to drive clean, accurate holes with minimal effort.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat - dramatically extending bit life compared to standard hammer drill bits so you replace bits less often
• Peak Point tip design enables aggressive starts - produces clean, fast holes for common sized anchors so you spend less time repositioning and more time drilling
• Optimized brazing and hardening process on carbide tips - increases tip longevity and maintains productivity across demanding concrete and brick drilling tasks
• Optimized four-flute design removes dust faster - keeps carbide tips cooler during operation, contributing to ultimate strength and durability over extended use
• SDS-Plus shank - compatible with both corded and cordless SDS-Plus rotary hammers for versatile use across tool platforms
• 2-cutter carbide-tipped head - provides balanced, efficient material removal when drilling concrete, brick, and block

Why This Product

• When speed and accuracy matter in concrete drilling, the Peak Point tip creates aggressive, self-starting holes that stay on target - reducing anchor installation time and rework
• The Dura-Carbide material and enhanced brazing process mean the bit holds up under repeated impact and heat, making it a cost-effective choice for high-volume anchor setting in concrete and masonry
• The four-flute dust evacuation design actively cools the tip during use, helping maintain bit integrity through long drilling sessions without frequent stops
• Compatibility with both corded and cordless SDS-Plus rotary hammers makes this 1/4 in. bit a flexible option for a wide range of job site setups

Frequently Asked Questions

What size holes does this bit drill?

This bit drills 1/4 in. diameter holes with a working length of 4 in. and an overall length of 6 in., making it well suited for setting common sized anchors in concrete and masonry.

Is this bit compatible with cordless rotary hammers?

Yes. The SDS-Plus shank is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers, giving you flexibility across tool platforms on the job site.

What materials can this hammer drill bit be used on?

This bit is designed for use on concrete and brick/block. The Dura-Carbide tip and Peak Point design are specifically engineered to handle the impact demands of these hard masonry materials.

How does the four-flute design benefit performance?

The optimized four-flute design removes dust from the hole faster during drilling. This keeps the carbide tip cooler during operation, which contributes to the bit's ultimate strength, durability, and extended service life.
