The Diablo 3/8" x 22" x 24" 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. Engineered by Diablo with Dura-Carbide technology and a precision four-flute design, this rotary hammer bit is built for professionals and serious DIYers who demand clean, fast holes in concrete and brick or block materials - without sacrificing tool or bit life. Optimized for use in both corded and cordless SDS-Plus rotary hammer drills, this bit brings German-engineered precision to demanding jobsite conditions.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat applications - dramatically extends bit life compared to standard hammer drill bits, reducing downtime and replacement costs
• Peak Point Tip design enables aggressive starts - produces clean, fast holes sized for common anchors, improving accuracy and reducing prep time on every hole
• Optimized brazing and hardening process locks in carbide tip integrity - extends tip life and keeps productivity high across long drilling sessions
• Optimized four-flute design removes dust faster - keeps carbide tips cooler during use for ultimate strength and durability, especially in deep or repeated-hole applications
• SDS-Plus shank - fits all standard SDS-Plus rotary hammer drills, both corded and cordless, for broad tool compatibility on any jobsite
• 3/8" diameter with 22" working length and 24" overall length - provides the reach needed to drill through thick concrete slabs or masonry walls in a single pass

Why This Product

• Built specifically for concrete and brick or block drilling, this bit handles the most common masonry anchor applications with a tip geometry that starts aggressively and stays centered, reducing bit walk and wasted effort
• The Dura-Carbide formulation and optimized brazing process directly address the two most common failure modes in hammer bits - tip loss from impact and tip degradation from heat - giving users measurably longer service life per bit
• At 24" overall length with a 22" working length, this SDS-Plus bit reaches deep into thick concrete or CMU block walls where shorter bits cannot, eliminating the need for extensions on most through-bolt and anchor installations
• Compatible with corded and cordless SDS-Plus rotary hammers, this bit integrates into existing tool setups without requiring dedicated hardware - a practical, cost-effective choice for contractors already working with SDS-Plus platforms

Frequently Asked Questions

What type of drill is required to use this bit?

This bit uses an SDS-Plus shank and is designed for use with SDS-Plus rotary hammer drills. It is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers.

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

The overall length of this bit is 24", which includes the SDS-Plus shank. The working length - the portion of the bit that actively drills into the material - is 22". This 22" working length gives the bit substantial reach for drilling through thick concrete slabs or masonry walls.

What makes Dura-Carbide different from standard carbide tips?

Diablo's Dura-Carbide is formulated to withstand both impact and high heat that occur during hammer drilling. Combined with the optimized brazing and hardening process, the carbide tips are secured more durably to the bit body, dramatically extending the life of the bit compared to standard hammer drill bits.

What materials can this bit drill through?

This Diablo SDS-Plus hammer drill bit is designed for drilling concrete and brick or block masonry. The Peak Point Tip and two-cutter design are optimized to produce clean, fast holes in these hard masonry materials for common anchor installations.
