The Diablo 5/16 in. x 10 in. x 12 in. SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered to deliver one of the fastest and longest lasting drilling solutions available for concrete and masonry work. Featuring Diablo's Dura-Carbide construction and a precision Peak Point Tip, this rotary hammer bit is built for professionals who demand clean, accurate holes with every pass through concrete, brick, and block. Optimized for both corded and cordless SDS-Plus rotary hammers, it combines aggressive cutting action with extended tip life - making it a reliable choice for anchor installation and general concrete drilling tasks.

Key Features

• Diablo Dura-Carbide construction - withstands repeated impact and high heat generated during hammer drilling, dramatically extending service life compared to standard hammer drill bits so you replace bits less often on the job.
• Peak Point Tip design - allows for aggressive starts that produce clean, fast holes sized for common anchors, reducing the need for repositioning and improving hole accuracy in concrete and block.
• Optimized brazing and hardening process - secures the carbide tips with greater bond strength and hardness, extending the productive life of the cutting edges and increasing drilling efficiency over the bit's lifetime.
• Optimized four-flute design - removes dust from the hole faster than standard two-flute configurations, keeping the carbide tips cooler during extended use for ultimate strength and durability.
• SDS-Plus shank - provides a secure, tool-free bit change and efficient energy transfer from corded or cordless SDS-Plus rotary hammers, minimizing vibration and maximizing drilling speed.
• 5/16 in. diameter with 10 in. working length and 12 in. overall length - sized for common anchor applications in concrete and masonry, giving you adequate depth capacity for through-the-wall and deep anchor installations.

Why This Product

• Concrete drilling demands a bit that stays sharp under repeated hammer impact and heat - Diablo's Dura-Carbide tip material and advanced brazing process address both of those failure points directly, giving the bit a longer usable life than standard carbide-tipped alternatives.
• The Peak Point Tip geometry starts cutting immediately on contact with concrete or brick surfaces, eliminating the bit walking that slows down anchor installation and reduces hole quality in hard masonry materials.
• The four-flute dust removal system keeps the cutting zone cooler during continuous drilling, which translates directly to more holes per bit before replacement is needed - a practical advantage on high-volume concrete anchoring projects.
• Compatibility with both corded and cordless SDS-Plus rotary hammers makes this bit a flexible choice whether working from a power outlet or relying on battery power in locations where cords are impractical.

Frequently Asked Questions

What rotary hammer tools is the DMAPL2200 compatible with?

This bit is designed for use with SDS-Plus rotary hammer drills and is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers. It is not intended for standard drill chucks or SDS-Max tool systems.

What materials can this hammer drill bit cut through?

The DMAPL2200 is rated for drilling concrete as well as brick and block masonry. The Dura-Carbide tip and Peak Point Tip design are specifically suited to the hardness and abrasiveness of these materials.

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

The overall length of this bit is 12 in., which includes the SDS-Plus shank that inserts into the tool. The working length - the portion of the bit that actively drills into the material - is 10 in. This means the maximum drilling depth achievable is 10 in.

Why does the four-flute design matter for concrete drilling performance?

The optimized four-flute design removes concrete dust from the hole faster during drilling. Faster dust evacuation keeps the carbide tips cooler during use, which helps maintain tip hardness and cutting efficiency, contributing to ultimate strength and durability over the life of the bit.
