The Diablo 3/8" x 37" x 39" 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 applications. Built by Diablo and manufactured in Germany, this heavy-duty rotary hammer bit combines advanced carbide technology with a precision tip design, giving contractors and tradespeople the speed, accuracy, and bit longevity they need when drilling anchor holes in concrete and brick or block. Whether you are working with a corded or cordless SDS-Plus rotary hammer, this bit is optimized to perform at maximum efficiency across both tool types.

Key Features

• Diablo Dura-Carbide construction - withstands high-impact and high-heat conditions, dramatically extending bit life compared to standard hammer drill bits so you replace bits less often and stay productive longer.
• Peak Point Tip design - enables aggressive starts that quickly center on the drilling surface, producing clean, fast holes sized for common anchors and reducing the chance of wandering or chipping.
• Optimized brazing and hardening process for carbide tips - the unique bonding and hardening method keeps carbide tips firmly secured and sharp under repeated hammer impacts, increasing both productivity and service life.
• Optimized four-flute design - removes concrete dust and debris faster during drilling, keeping carbide tips cooler for ultimate strength and durability throughout extended use.
• SDS-Plus shank - locks securely into any SDS-Plus rotary hammer chuck, providing reliable bit retention and efficient transfer of hammering energy into the material being drilled.
• 39" total length with 37" working length - allows users to reach deep through walls, concrete floors, or block assemblies where shorter bits cannot reach, expanding the range of anchor and through-hole applications.
• Compatible with corded and cordless SDS-Plus rotary hammers - delivers consistent performance across tool types, giving jobsite flexibility regardless of the power source available.

Why This Product

• For tradespeople who drill anchor holes in concrete and brick regularly, the Dura-Carbide tip material and optimized brazing process means significantly fewer bit changes and lower overall tooling cost per hole compared to standard hammer bits.
• The Peak Point Tip design addresses one of the most common frustrations in concrete drilling - slow, imprecise starts - by allowing aggressive, centered entry that produces clean holes matched to common anchor diameters.
• At 39" total length with a 37" working length, this bit solves the reach problem on deep anchor installations and through-wall applications where standard-length bits fall short.
• The four-flute flute design actively removes dust during drilling rather than allowing it to pack around the tip, which keeps the carbide cooler and maintains cutting performance over long drilling sessions without heat-related degradation.

Frequently Asked Questions

What type of rotary hammer is this bit compatible with?

This bit is designed for use with SDS-Plus rotary hammer drills, both corded and cordless. The SDS-Plus shank securely locks into the chuck of any SDS-Plus compatible rotary hammer, providing reliable bit retention and efficient hammer energy transfer during drilling.

What materials can this bit drill through?

This Diablo SDS-Plus hammer drill bit is rated for use in concrete and brick/block masonry. The Peak Point Tip design and Dura-Carbide construction are specifically optimized for these hard masonry materials, producing clean, accurate holes for anchor installation.

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

The total length of 39" refers to the overall measurement of the bit from end to end, while the working length of 37" refers to the portion of the bit that actively engages the material and removes debris. The SDS-Plus shank occupies the remaining length and seats inside the rotary hammer chuck.

How does the four-flute design benefit drilling performance?

The optimized four-flute design removes concrete dust and debris more quickly from the hole during drilling. Faster dust evacuation keeps the carbide tips cooler during extended use, which preserves the sharpness and structural integrity of the tip for ultimate strength and durability over the life of the bit.
