The Diablo 1" x 8" x 10" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered to deliver fast, accurate holes in concrete and masonry with exceptional durability. Built by Diablo with Dura-Carbide technology and a precision brazing process, this SDS Plus shank bit is purpose-built for rotary hammer applications where speed, consistency, and long service life matter most. Whether you're setting anchors in poured concrete or drilling through brick and block, this bit is designed to keep up with demanding jobsite conditions in both corded and cordless SDS-Plus rotary hammer drills.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat - dramatically extends service life compared to standard hammer drill bits, reducing replacement frequency and downtime
• Peak Point Tip design allows for aggressive starts - produces clean, fast holes that are accurately sized for common anchor installations
• Optimized brazing and hardening process extends life of carbide tips - increases productivity by maintaining cutting performance over more holes and longer use cycles
• Optimized four-flute design removes dust faster - keeps carbide tips cooler during drilling, preserving ultimate tip strength and long-term durability
• SDS Plus shank - compatible with both corded and cordless SDS-Plus rotary hammer drills, giving flexibility across tool types on the jobsite
• 2-cutter carbide-tipped head - provides efficient material removal in concrete and brick/block applications
• 8" working length with 10" overall length - delivers reach for deep anchor holes while maintaining control and stability
• 1" diameter - correctly sized for common anchor and fastener applications in concrete and masonry work

Why This Product

• If you need to drill anchor holes in concrete quickly without sacrificing accuracy, the Peak Point Tip design delivers aggressive starts and clean, properly sized holes - cutting down on rework and anchor fitment issues.
• The Dura-Carbide material combined with an optimized brazing and hardening process means the cutting tips hold up through high-impact, high-heat drilling conditions where standard carbide bits wear out prematurely.
• The four-flute flute geometry actively clears concrete dust from the hole during drilling, keeping the bit cooler and reducing the heat buildup that shortens bit life - a direct advantage in sustained drilling tasks.
• With compatibility across both corded and cordless SDS-Plus rotary hammers, this bit works with the widest range of rotary hammer tools, making it a practical choice for contractors who use multiple tool platforms.

Frequently Asked Questions

What type of drill is required to use this bit?

This bit requires an SDS-Plus rotary hammer drill. It is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers. It is not compatible with standard keyless chuck drills.

What materials can this hammer drill bit drill through?

This bit is designed for use in concrete and brick/block masonry. The Dura-Carbide tip and Peak Point Tip design are specifically suited to these hard masonry materials.

What is the difference between the working length and the overall length?

The overall length of the bit is 10", which includes the SDS Plus shank. The working length - the portion of the bit that actively drills into the material - is 8". This means you can achieve an 8" depth of cut in concrete or masonry.

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

The optimized four-flute design is engineered to remove concrete dust from the hole more rapidly during drilling. Faster dust evacuation keeps the carbide tips cooler, which reduces heat-related wear and preserves the strength and durability of the cutting tips over a longer service life.
