Diablo 3/4" x 22" x 24" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered for professionals who need fast, precise holes in concrete and masonry. Designed for use with corded and cordless SDS-Plus rotary hammer drills, this bit delivers one of the fastest and longest lasting drilling solutions available for concrete work. With a 3/4" diameter, 24" overall length, and 22" working length, it is built to reach depth requirements common in anchor installation and structural concrete drilling applications.

Key Features

• Diablo Dura-Carbide construction - withstands impact and high heat, dramatically extending working life compared to standard hammer bits and reducing the need for frequent bit replacement
• Peak Point tip design - enables aggressive starts that produce clean, fast holes, making anchor-sized holes quicker and more accurate with less walking or skipping at the surface
• Optimized brazing and hardening process - extends the service life of the carbide tips and increases productivity, meaning fewer interruptions and lower cost per hole over the life of the bit
• Optimized four-flute design - removes dust faster from the bore, keeping carbide tips cooler for sustained strength and durability during extended drilling sessions
• 2-cutter carbide-tipped head - provides reliable cutting geometry for drilling into concrete and brick/block with consistent hole quality
• SDS-Plus shank - compatible with both corded and cordless SDS-Plus rotary hammer drills, offering versatile jobsite use without adapters
• Made in Germany - manufactured to stringent quality standards, reflected in the precision brazing and carbide hardening processes

Why This Product

• The Dura-Carbide tip material is specifically formulated to handle the repeated impact and heat generated in rotary hammer drilling, giving users a noticeably longer working life versus standard carbide hammer bits - reducing downtime and replacement costs on demanding concrete projects.
• The Peak Point tip geometry initiates drilling aggressively on contact, eliminating the slow start common with lesser bits and resulting in cleaner holes suited for common anchor sizes used in concrete and block construction.
• The four-flute dust evacuation design actively keeps the cutting zone cooler, which directly benefits users running cordless rotary hammers where heat buildup can shorten both bit life and battery cycles.
• At 24" overall length with a 22" working length and 3/4" diameter, this bit is well matched for deep anchor bolt and fastener installations in concrete slabs, walls, and masonry block that shorter bits simply cannot reach.

Frequently Asked Questions

What type of drill is required to use this bit?

This bit uses an SDS Plus shank and is optimized for use with SDS-Plus rotary hammer drills - both corded and cordless models are compatible. It is not intended for use in standard keyless chuck drills.

What materials can this hammer drill bit drill through?

This bit is designed for drilling concrete and brick/block masonry. The Dura-Carbide 2-cutter tip and Peak Point design are specifically optimized for these hard masonry materials.

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 that seats into the rotary hammer. The working length - the portion of the bit that actively drills into the material - is 22". This longer working length makes the bit well suited for deep anchor installations and through-drilling applications in concrete.

How does the four-flute design benefit performance?

The optimized four-flute design removes drilling dust from the bore more quickly than a two-flute configuration. Faster dust evacuation keeps the carbide tips cooler during extended use, which helps maintain tip strength and durability and extends the overall working life of the bit.
