The Diablo 7/16 in. x 6 in. x 8 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 applications. Engineered by Diablo with Dura-Carbide technology and a precision Peak Point Tip, this SDS Plus rotary hammer bit is built for contractors and serious DIYers who demand clean, accurate holes in concrete and brick or block without slowing down on the job site.

Key Features

• Diablo Dura-Carbide construction withstands high-impact and high-heat conditions - dramatically extending service life compared to standard hammer drill bits, so you spend less time swapping bits and more time drilling
• Peak Point Tip design enables aggressive, self-starting entry into concrete and masonry surfaces - producing clean, fast holes that are properly sized for common anchors without chipping or wandering
• Optimized brazing and hardening process locks carbide tips securely in place - increasing tip longevity and maintaining productivity through demanding, repetitive drilling tasks
• Four-flute geometry evacuates dust and debris faster than basic two-flute designs - keeping carbide tips cooler during extended use for maximum strength, durability, and hole quality
• SDS Plus shank is compatible with corded and cordless SDS-Plus rotary hammer drills - giving you the flexibility to use the bit with the power source that suits your work environment

Why This Product

• Designed specifically for drilling concrete and brick or block, this bit handles the demanding impact forces of rotary hammer drilling without the rapid tip wear that shortens the life of standard carbide bits
• The 6 in. working length provides sufficient reach for setting anchors and through-hole applications in common concrete slab and block wall thicknesses, while the 8 in. overall length keeps the bit manageable in tight spaces
• The 7/16 in. diameter is a commonly required anchor hole size, making this bit a practical, frequently-used addition to any concrete drilling kit rather than a specialty tool that sits idle
• Made in Germany, this bit reflects precision manufacturing standards - the Dura-Carbide material and proprietary hardening process translate directly into measurable productivity gains when drilling repetitive holes in concrete

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, so either power source type is compatible.

What materials can this hammer drill bit cut through?

This bit is designed for use in concrete and brick or block. The Dura-Carbide tip and Peak Point Tip design are specifically engineered for the impact and abrasion demands of these hard masonry materials.

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

The overall length of this bit is 8 in., which is the full measurement from shank end to tip. The working length - the portion of the bit that actively cuts into the material - is 6 in. This is the maximum effective drilling depth this bit can achieve in a single pass.

Why does this bit stay cooler than standard hammer bits during drilling?

The optimized four-flute design removes dust and debris from the hole faster than basic flute configurations. Faster dust evacuation reduces heat buildup at the carbide tips, helping maintain tip integrity and drilling efficiency over extended use in concrete and masonry.
