The Diablo 7/16 in. x 10 in. x 12 in. SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered for professionals who need fast, accurate holes in concrete and masonry without sacrificing tool life. Diablo's proprietary Dura-Carbide construction and precision four-flute geometry make this SDS-Plus rotary hammer bit one of the most capable options available for anchor installation and general concrete boring tasks. Whether you are working with corded rotary hammers on a job site or a cordless SDS-Plus tool in tighter spaces, this 7/16 in. diameter bit delivers consistent, clean results through concrete and brick or block materials.

Key Features

• Diablo Dura-Carbide construction withstands high-impact and high-heat drilling conditions - dramatically extending service life compared to standard hammer drill bits so you replace bits less often and stay productive longer
• Peak Point Tip design enables aggressive starts with minimal skipping - produces clean, fast holes sized for common anchors so positioning and hole quality are consistent from the first contact
• Optimized brazing and hardening process secures carbide tips with greater bond integrity - extending tip life and maintaining cutting performance through demanding concrete drilling applications
• Optimized four-flute flute design evacuates dust and debris faster - keeping carbide tips cooler during operation for ultimate cutting strength and long-term durability in repetitive drilling tasks
• SDS-Plus shank - compatible with both corded and cordless SDS-Plus rotary hammer drills, giving you flexibility across tool brands and power sources
• 2-cutter carbide-tipped head - delivers faster penetration rates and longer-lasting cutting edges than single-cutter alternatives when boring through concrete and masonry

Why This Product

• If you are setting anchors in concrete or block regularly, the Peak Point Tip design starts aggressively without wandering, producing holes that are sized correctly for common anchors the first time - reducing rework on the job site
• The Dura-Carbide material with its optimized brazing and hardening process means the cutting tips stay intact longer under impact and heat, giving you more holes per bit and lowering per-hole cost over time
• The four-flute configuration actively clears dust from the bore during drilling, which keeps the bit cooler and reduces the risk of premature carbide degradation in deep or repetitive concrete holes
• With a 12 in. overall length and 10 in. working length, this bit handles deeper anchor placements and reaches into recessed areas that shorter bits simply cannot access

Frequently Asked Questions

What type of rotary hammer is this bit compatible with?

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

What materials can this hammer drill bit bore through?

This bit is designed for drilling concrete as well as brick and block masonry materials. It is not intended for wood, metal, or tile applications.

What does the four-flute design do during concrete drilling?

The optimized four-flute design removes dust faster from the bore during drilling, which keeps the carbide tips cooler. Cooler tips maintain their strength and durability longer, especially during repetitive or deep drilling tasks.

How does the overall length relate to the working length on this bit?

This bit has a 12 in. overall length with a 10 in. working length. The working length represents the fluted cutting section that actively engages the material, while the overall length accounts for the SDS-Plus shank that seats into the rotary hammer chuck.
