DeWALT 1/4 in. x 4 in. x 6 in. SDS Plus 2 Cutter Drill Bits (25-Pack) are carbide-tipped hammer bits engineered for fast, accurate drilling into concrete, masonry, and rock. Designed for SDS-Plus rotary hammer chucks, this bulk pack of 25 bits delivers the consistent performance and durability that demanding masonry and anchor installation work requires - whether you are drilling for anchor rods, fasteners, or structural hardware in concrete.

Key Features

• Strong Tapered Core - resists flute breaks during deep-hole drilling, reducing bit failure and downtime on tough concrete applications
• Two-Stage Flute Design with Variable Helix Pattern - aggressively moves debris away from the contact zone for faster, more efficient drilling with less friction buildup
• Two Sharp Carbide Cutting Edges - deliver clean, round holes that support secure, reliable anchor installation in masonry and concrete
• Wear Mark Indicator - lets you confirm the hole diameter is still accurate throughout the bit's working life, supporting consistent results
• DeWALT Carbide Tip Design - maximizes carbide surface contact for longer bit life, reducing replacement frequency on high-volume drilling tasks
• No Break Guarantee - if the bit fails for any reason while the wear mark is still visible, DeWALT will replace it, giving you added confidence on the job
• SDS-Plus Chuck Compatibility - fits standard SDS-Plus rotary hammer chucks for secure tool-free bit changes and efficient hammer energy transfer

Why This Product

• Bulk value for high-volume crews - the 25-pack format means fewer reorders and more uptime when running multiple rotary hammers or tackling large anchor installation projects in concrete and masonry
• Built for deep holes without bit failure - the tapered core construction specifically addresses the stress points that cause flute breaks in deep-hole drilling, making these bits reliable for through-slab and deep embedment work
• Backed by a no break guarantee - DeWALT's replacement commitment while the wear mark is visible means you are not absorbing the cost of a premature bit failure, a meaningful protection for production environments
• Two-cutter design for cleaner anchor holes - the dual carbide cutting edges produce true, round holes that meet the dimensional requirements for secure mechanical anchor installation in rock, block, and concrete

Frequently Asked Questions

What is the No Break Guarantee and what does it cover?

If your DeWALT bit fails for any reason while the wear mark is still visible, DeWALT will replace it. This guarantee excludes models DW5400, DW5401, and DW5401B25. The wear mark indicator on the bit helps you confirm whether the guarantee is still applicable during use.

What type of rotary hammer is this bit compatible with?

This bit uses an SDS-Plus chuck interface, which fits SDS-Plus rotary hammers. The SDS-Plus shank allows for tool-free bit changes and efficient hammer energy transfer into the bit during concrete and masonry drilling.

Why does the two-stage flute design matter for concrete drilling?

The two-stage flute design features a variable helix pattern that efficiently moves debris away from the cutting zone during drilling. This helps maintain optimal drilling speeds and reduces heat buildup, particularly important during repeated or deep-hole drilling in concrete, rock, and masonry.

Is this bit suitable for anchor installation?

Yes. The two sharp carbide cutting edges are designed to produce clean, round holes - the type of true, accurate bore needed for secure mechanical anchor installation. The wear mark indicator also helps confirm that the hole diameter remains within spec throughout the bit's working life.
