Diablo 3/8" x 16" x 18" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered for professionals who need fast, accurate holes in concrete and masonry. Built with Diablo's proprietary Dura-Carbide technology and a precision Peak Point tip, this SDS-Plus rotary hammer bit delivers one of the fastest and longest lasting drilling solutions available for concrete anchoring and block work. Whether you are setting anchors in poured concrete or drilling through brick and block, this 3/8" diameter bit is optimized for both corded and cordless SDS-Plus rotary hammers, keeping you productive on the job site.

Key Features

• Dura-Carbide construction withstands impact and high heat - dramatically extends service life versus standard hammer drill bits, reducing bit replacement frequency and total cost on demanding concrete drilling jobs.
• Peak Point tip design for aggressive starts - produces clean, fast holes from the first contact, which means less wandering and more accurate placement for common anchor sizes.
• Unique brazing and hardening process applied to carbide tips - increases the structural integrity of the carbide, extending tip life and sustaining higher productivity over the full working life of the bit.
• Optimized four-flute design removes debris faster - keeping carbide tips cooler during continuous drilling, which translates to greater strength, durability, and fewer interruptions to clear dust from the hole.
• 3/8" diameter with 16" working length and 18" overall length - provides the reach needed for deep anchor installations while the SDS-Plus shank ensures a secure, tool-free chuck connection with compatible rotary hammers.

Why This Product

• The four-flute dust removal geometry and Dura-Carbide tips work together to keep the bit running cooler and longer - a practical advantage when drilling multiple holes in concrete or block without stopping to swap bits.
• The Peak Point tip geometry allows for aggressive, self-centering starts in concrete and brick, reducing the need for a center punch or slow startup speed - saving time when setting anchors in high-volume applications.
• Compatible with both corded and cordless SDS-Plus rotary hammers, this bit adapts to the tool you already own, making it a versatile addition to any concrete drilling kit.
• Made in Germany with a specialized carbide brazing and hardening process, this bit is built to a higher standard than typical hammer bits - delivering reliable hole quality in concrete and masonry applications where precision matters.

Frequently Asked Questions

What type of rotary hammer is this bit designed to work with?

This bit features an SDS-Plus shank and is optimized for use with SDS-Plus rotary hammer drills. It is compatible with both corded and cordless SDS-Plus rotary hammers.

What materials can this hammer drill bit drill through?

This bit is designed for drilling concrete and brick/block. The Dura-Carbide tips and Peak Point design make it particularly effective for creating clean, accurate holes in these masonry materials.

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

The overall length of this bit is 18", which includes the SDS-Plus shank that seats inside the rotary hammer chuck. The working length - the portion of the bit that actively drills into the material - is 16". This working length determines the maximum depth you can drill in a single pass.

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

The optimized four-flute design removes dust and debris from the hole faster than fewer-flute designs. This faster dust evacuation keeps the carbide tips cooler during drilling, which helps maintain tip strength and durability over the life of the bit - especially important during extended or high-volume concrete drilling work.
