Diablo 1/4" x 4" x 6" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bits (25-Pack) by Diablo deliver one of the fastest and longest-lasting drilling solutions available for concrete and masonry work. Engineered with Dura-Carbide technology and a precision-hardened tip, these bits are built for contractors and tradespeople who demand reliable performance in tough materials like concrete and brick. This pack of 25 ensures you have the supply needed for high-volume anchoring and fastening jobs, whether you are running a corded or cordless SDS-Plus rotary hammer.

Key Features

• Diablo Dura-Carbide construction withstands heavy impact and high heat - dramatically extends service life compared to standard hammer drill bits, reducing replacement frequency on busy job sites
• Peak Point Tip design allows for aggressive starts - produces clean, fast holes sized accurately for common anchors, minimizing rework and material waste
• Optimized brazing and hardening process on the carbide tips - increases tip longevity and drilling productivity, so jobs get done faster with fewer bit changes
• Four-flute design removes dust faster during drilling - keeps carbide tips cooler for ultimate strength and durability through extended use in concrete and brick/block
• SDS-Plus shank - compatible with both corded and cordless SDS-Plus rotary hammers for flexible use across different tool setups
• 25-piece pack - provides ample supply for large commercial projects or high-volume anchor installation without repeated single-bit purchases

Why This Product

• For concrete anchor installation, the Peak Point Tip produces clean, accurately sized holes that seat anchors correctly - reducing the risk of loose or misaligned fasteners
• The four-flute dust evacuation design actively cools the bit during use, which translates to fewer heat-related failures and a longer working life per bit - critical on large pours or block walls
• The unique brazing and hardening process is specifically optimized to resist the punishing cycle of impact and heat that SDS-Plus hammer drilling generates, giving these bits a performance edge over generic carbide-tipped alternatives
• A pack of 25 is purpose-built for professional volume - ideal for contractors setting multiple anchors across a site without stopping to reorder individual bits

Frequently Asked Questions

What materials can these Diablo SDS-Plus hammer drill bits be used on?

These bits are approved for use on concrete and brick/block. The Dura-Carbide tip and Peak Point Tip design are specifically engineered to handle the hardness and abrasion of masonry materials, producing clean holes for anchor installation.

Are these bits compatible with cordless SDS-Plus rotary hammers?

Yes. These Diablo SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bits are optimized for maximum performance in both corded and cordless SDS-Plus rotary hammers.

What is the working length versus the overall length of these bits?

Each bit has an overall length of 6" and a working length of 4". The working length is the active cutting depth available during drilling, while the remaining length is the SDS-Plus shank used for chuck engagement.

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

The optimized four-flute design removes dust from the hole faster than fewer-flute configurations. Faster dust removal keeps the carbide tip cooler during drilling, which preserves tip integrity and contributes to ultimate strength and durability over the life of the bit.
