The Diablo 5/16 in. x 16 in. x 18 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 applications. Built with Diablo's proprietary Dura-Carbide material and a unique brazing and hardening process, this rotary hammer bit maintains sharp, accurate cutting performance through demanding jobsite conditions - whether you are using a corded or cordless SDS-Plus rotary hammer. Designed for contractors and tradespeople who rely on speed, precision, and durability when anchoring into concrete and brick, this bit stands apart from standard carbide-tipped options through its optimized flute geometry and Peak Point tip design.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat applications - dramatically extending working life versus standard hammer drill bits so you replace bits less often and stay productive longer
• Peak Point tip design for aggressive starts that produce clean, fast holes - ideal for common anchor sizes and reducing the need for repositioning or pilot holes
• Optimized brazing and hardening process extends the life of the carbide tips and increases productivity - meaning more holes per bit and lower cost per hole over time
• Optimized four-flute design removes dust faster, keeping the carbide tips cooler for ultimate strength and durability - reducing heat buildup that can prematurely wear or fracture lesser bits
• SDS-Plus shank is compatible with all corded and cordless SDS-Plus rotary hammer drills - offering broad tool compatibility across common jobsite platforms
• 5/16 in. diameter with a 16 in. working length and 18 in. overall length - provides the reach needed for deep anchor installations in concrete and block applications

Why This Product

• Contractors needing to drill anchor holes fast and accurately in concrete will benefit from the Peak Point tip and Dura-Carbide formula, which work together to start cleanly and stay sharp through repeated use
• The four-flute dust removal design keeps the tip cooler during sustained drilling in hard concrete or brick/block, which directly reduces the risk of premature tip failure on difficult materials
• With a 16 in. working length on an 18 in. overall bit, this is a purpose-built solution for deep anchor placements where standard-length bits fall short
• Made in Germany with a unique hardening process, this bit is optimized for both corded and cordless SDS-Plus rotary hammers - giving users flexibility across their existing tool inventory without sacrificing performance

Frequently Asked Questions

What type of tool is required to use this hammer drill 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, making it compatible with a wide range of tools commonly found on jobsites.

What materials can this bit drill into?

This Diablo SDS-Plus 2-Cutter bit is designed for drilling concrete as well as brick and block masonry. The Dura-Carbide tip is specifically engineered to handle the impact and abrasion demands of these hard materials.

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

The overall length of this bit is 18 in., which includes the SDS-Plus shank. The working length - the portion of the bit that actively drills into the material - is 16 in. This extended working length allows for deep anchor hole drilling where a shorter bit would not reach.

How does the four-flute design benefit drilling performance?

The optimized four-flute design removes dust from the hole faster than a standard two-flute configuration. Faster dust evacuation keeps the carbide tip cooler during drilling, which preserves tip strength and durability and helps the bit last significantly longer than standard hammer drill bits.
