The Diablo 1/4" x 2" x 4" SDS-Plus 2-Cutter Carbide-Tipped Hammer Drill Bit is engineered for contractors and tradespeople who need fast, accurate holes in concrete and masonry. Diablo's signature Dura-Carbide construction and Peak Point Tip geometry make this bit a go-to choice for anchor installations, concrete fastening, and general masonry drilling where clean holes and long bit life matter most. Compatible with both corded and cordless SDS-Plus rotary hammer drills, this 1/4" diameter bit delivers reliable performance across a wide range of concrete and brick applications.

Key Features

• Diablo Dura-Carbide construction withstands impact and high heat - dramatically extends service life compared to standard hammer drill bits, reducing replacement costs and downtime on the job
• Peak Point Tip design for aggressive starts that produce clean, fast holes - allows precise positioning and smooth entry into concrete without wandering, ideal for common anchor sizes
• Optimized brazing and hardening process extends life of carbide tips and increases productivity - carbide tips stay bonded and sharp longer, keeping work moving at a consistent pace
• Optimized four-flute design removes dust faster, keeping the carbide tips cooler for ultimate strength and durability - improved debris evacuation means less heat buildup and a longer-lasting cutting edge
• SDS-Plus shank design - locks securely into SDS-Plus rotary hammer chucks for positive power transfer and quick, tool-free bit changes
• Made in Germany - precision manufacturing ensures consistent carbide tip geometry and reliable performance across every hole drilled

Why This Product

• Designed specifically for concrete and brick/block drilling, this bit addresses one of the most demanding masonry tasks - anchor hole placement - with a tip geometry and carbide grade optimized to cut fast and stay sharp across many holes
• The combination of Dura-Carbide tips and an optimized brazing process means the carbide is less likely to crack or separate under the repeated impact stress of rotary hammer drilling, giving users more holes per bit
• The four-flute dust evacuation design keeps the cutting zone cooler, which directly translates to less tip wear and more consistent hole diameter over the life of the bit
• At 1/4" diameter with a 2" working length, this bit is sized for the common anchor hole depths used in everyday concrete fastening tasks, making it a practical single-purchase solution for anchor installation work

Frequently Asked Questions

What rotary hammer tools is this bit compatible with?

This bit is designed for use with SDS-Plus rotary hammer drills. It is optimized for maximum performance in both corded and cordless SDS-Plus rotary hammer models.

What materials can this bit drill through?

This Diablo SDS-Plus hammer drill bit is rated for drilling into concrete and brick/block. The Dura-Carbide tip construction is specifically designed to handle the impact stress and abrasion associated with these hard masonry materials.

What is the working length and why does it matter?

The working length - the portion of the bit that actively cuts - is 2". This determines the maximum depth of hole you can produce. The overall bit length is 4", which accounts for the SDS-Plus shank engagement inside the chuck. For standard anchor installations in concrete, a 2" working length covers the most common hole depth requirements.

How does the four-flute design benefit drilling performance?

The optimized four-flute design removes dust and debris from the hole faster during drilling. Faster dust evacuation keeps the carbide tips cooler, which reduces heat-related wear and helps maintain the tip's cutting geometry over a longer service life - meaning more holes before the bit needs to be replaced.
