The Diablo 1/2 in. x 16 in. x 18 in. SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit delivers one of the fastest and longest lasting drilling solutions available for concrete and masonry work. Engineered by Diablo with a proprietary Dura-Carbide formulation and a precision brazing and hardening process, this SDS-Plus bit is built to handle demanding rotary hammer applications with speed, accuracy, and extended tool life. Whether you are anchoring into poured concrete or drilling through brick and block, this 1/2 in. diameter bit provides reliable, clean hole production job after job.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat applications - dramatically extends service life compared to standard hammer drill bits, reducing replacement frequency and downtime on the job
• Peak Point Tip design for aggressive starts that produce clean, fast holes - allows work to begin immediately without walking or wandering, resulting in precise anchor-ready holes
• Optimized brazing and hardening process extends life of carbide tips and increases productivity - the carbide bond holds stronger under repeated hammer blows, keeping the bit cutting efficiently longer
• Optimized four-flute design removes dust faster, keeping the carbide tips cooler for ultimate strength and durability - faster dust evacuation means less heat buildup and less risk of premature tip wear
• SDS Plus shank - compatible with both corded and cordless SDS-Plus rotary hammers, giving users flexibility across a range of jobsite tools
• 16 in. working length with 18 in. overall length - provides deep reach for through-bolts, anchor installation, and other applications requiring extended bit depth

Why This Product

• Designed specifically for drilling concrete, brick, and block - the carbide tip geometry and flute design are tuned for masonry, not adapted from general-purpose bits, so users get results optimized for the material at hand
• The Peak Point Tip and Dura-Carbide formulation work together to start aggressively and maintain cutting speed - meaning fewer passes, less pressure required, and faster hole completion when setting common anchor sizes
• The four-flute dust removal design keeps the bit cooler during extended drilling sessions - a cooler bit retains carbide integrity longer, giving contractors and tradespeople more holes per bit before replacement
• Works with both corded and cordless SDS-Plus rotary hammers - a single bit covers multiple tools on the jobsite, making it a practical choice for crews that run mixed power tool setups

Frequently Asked Questions

What type of hammer drill is this bit 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.

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 makes the bit suitable for deep anchor holes and through-bolt applications in concrete and masonry.

What materials can this hammer drill bit be used on?

This Diablo SDS-Plus bit is designed for use on concrete and brick/block masonry. The Dura-Carbide tip and four-flute design are both optimized for these hard masonry materials.

What makes the Peak Point Tip design beneficial for concrete drilling?

The Peak Point Tip design allows for aggressive starts that produce clean, fast holes. This means the bit engages the concrete surface quickly without slipping, which is especially useful when drilling holes for common anchor sizes where hole accuracy and cleanliness are critical.
