The Diablo 7/32" x 10" x 12" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered to deliver fast, accurate holes in concrete and masonry with exceptional durability. Designed by Diablo for use in corded and cordless SDS-Plus rotary hammer drills, this hammer drill bit combines a precision-ground Peak Point tip with Dura-Carbide construction to handle demanding drilling tasks in concrete and brick or block materials. Whether you are setting anchors or working through reinforced masonry, this bit offers a reliable solution built to last longer and drill faster than standard hammer bits.

Key Features

• Diablo Dura-Carbide construction - withstands heavy impact and high heat generated during concrete drilling, dramatically extending service life compared to standard hammer bits so you replace bits less often on the job.
• Peak Point Tip design - enables aggressive starts that quickly center and penetrate the work surface, producing clean, fast holes sized correctly for common anchors without wandering or chipping.
• Optimized brazing and hardening process on carbide tips - increases the bond strength and longevity of the cutting edges, sustaining productivity through extended drilling sessions without premature tip wear.
• Optimized four-flute design - evacuates dust from the hole faster, keeping carbide tips cooler during operation for ultimate strength and durability across repeated drilling cycles.
• SDS-Plus shank - locks securely into SDS-Plus rotary hammer chucks for efficient power transfer and easy, tool-free bit changes on both corded and cordless rotary hammers.
• 7/32" diameter with a 10" working length and 12" overall length - provides the reach needed for deep anchor holes while maintaining the precise bore size required for common fastener applications.
• 2-cutter carbide-tipped head - delivers consistent cutting performance in concrete and brick or block, making it a practical choice for everyday masonry work.

Why This Product

• The Dura-Carbide tip material and unique brazing and hardening process means this bit holds up in high-heat, high-impact concrete applications where standard hammer bits fail early - reducing downtime and replacement costs.
• The Peak Point Tip design is particularly well suited for anchor installation work, where a clean, accurately sized hole is critical - reducing the risk of anchor misalignment or hole damage that can compromise holding strength.
• The four-flute dust removal design keeps the tip cooler during continuous use, which directly supports durability and consistent cutting speed across long drilling sessions in concrete or brick or block.
• Manufactured in Germany and optimized for both corded and cordless SDS-Plus rotary hammers, this bit provides broad compatibility for professionals who use different tools across various job sites.

Frequently Asked Questions

What type of drill is required to use this bit?

This bit is designed for use with SDS-Plus rotary hammer drills - both corded and cordless models. It features an SDS-Plus shank that locks into compatible chucks for secure, efficient power transfer. It is not intended for use with standard drill drivers or keyless chuck drills.

What materials can this hammer drill bit drill through?

This Diablo SDS-Plus hammer drill bit is designed for drilling concrete and brick or block masonry. It is particularly suited for creating clean, accurate holes for common-sized anchors in these materials.

What is the difference between the overall length and the working length of this bit?

The overall length of this bit is 12", which includes the SDS-Plus shank portion that seats inside the drill chuck. The working length - the portion of the bit that actively drills into the material - is 10". This distinction matters when planning hole depth for anchor installation or when drilling through thick concrete sections.

How does the four-flute design benefit drilling performance?

The optimized four-flute design removes dust from the hole faster than fewer-flute designs. By evacuating debris more efficiently, the flutes keep the carbide tips cooler during operation, which helps maintain tip hardness and cutting sharpness for ultimate strength and durability over the life of the bit.
