Diablo 3/8" x 10" x 12" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit by Diablo is engineered for contractors and tradespeople who need fast, reliable, and long-lasting performance when drilling into concrete, brick, and block. Built with Diablo's Dura-Carbide technology and a precision Peak Point Tip, this SDS-Plus rotary hammer bit delivers aggressive starts, clean holes, and exceptional durability in demanding masonry applications.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat applications - dramatically extending bit life compared to standard hammer bits so you replace tooling less often and stay productive longer
• Peak Point Tip design for aggressive starts that produce clean, fast holes - reduces walking at the start of a hole and delivers precise, anchor-ready results in concrete and masonry
• Optimized brazing and hardening process extends life of carbide tips and increases productivity - the secure tip bond means less chipping and more consistent performance over the life of the bit
• Optimized four-flute design removes dust faster, keeping the carbide tips cooler for ultimate strength and durability - faster debris evacuation means reduced heat buildup and longer-lasting cutting edges
• SDS-Plus shank - fits all SDS-Plus rotary hammer drills for a secure, tool-free bit change with positive engagement and zero slippage during high-impact drilling
• 3/8" diameter with 10" working length and 12" overall length - sized for common anchor holes in concrete and block with enough reach for deeper embedments

Why This Product

• For concrete drilling where speed and hole quality matter, the Peak Point Tip and four-flute dust evacuation design work together to produce clean, accurate holes faster than standard hammer bits - reducing time on each bore.
• The Dura-Carbide formulation is specifically designed to handle the combined stress of impact force and heat generated by SDS-Plus rotary hammers, meaning fewer bit replacements and lower cost per hole over a full project.
• The optimized brazing and hardening process on the carbide tips gives this bit a durability advantage in tough masonry materials like concrete and brick or block, where tip failure is a common frustration with lower-grade bits.
• Manufactured in Germany, this bit reflects precision engineering standards that translate directly into consistent cutting geometry, reliable tip retention, and repeatable hole quality across the full working life of the bit.

Frequently Asked Questions

What type of drill is required to use this bit?

This bit requires an SDS-Plus rotary hammer drill. The SDS-Plus shank provides a secure, positive-locking connection specifically designed for the rotary hammering action needed to drill through concrete, brick, and block.

What is the difference between overall length and working length?

The overall length of this bit is 12", which includes the SDS-Plus shank portion that seats inside the tool. The working length - the portion of the bit that actively engages the material - is 10". This working length determines the maximum depth you can drill in a single pass.

What makes Dura-Carbide different from standard carbide hammer bit tips?

Diablo's Dura-Carbide is engineered to withstand both the impact stress and high heat generated during hammer drilling, conditions that can cause standard carbide tips to chip or wear prematurely. The optimized brazing and hardening process further secures the tips to dramatically extend bit life versus standard hammer bits.

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

The optimized four-flute design removes dust faster from the bore hole during drilling. Faster dust evacuation keeps the carbide tips cooler, which preserves tip hardness and sharpness for greater strength and durability over the life of the bit - a meaningful advantage during extended concrete or masonry drilling tasks.
