1-1/8 in x 18 in SDS Plus Rotary Hammer Drill Bit - Masonry Duty

In this review the 1-1/8 in x 18 in SDS Plus rotary hammer drill bit is assessed for contractors and serious DIYers needing a large-diameter masonry bit. The bottom line: it is best for drilling deep, clean holes in brick, stone, concrete and block where a carbide-tipped, self-centering design speeds cutting and extends life. Tested in heavy masonry tasks, the bit stands out for fast cut speed and chip evacuation, though a few users reported mixed durability under extreme side loading. Overall it is a focused tool for SDS Plus rotary hammers.

Key Features

• 1-1/8 in diameter: Provides a large, consistent hole size suitable for anchors and sleeves in concrete and block.
• SDS Plus shank compatibility: Works with most SDS Plus rotary hammer drills from common brands, allowing quick tool changes.
• 2-flute carbide tip: The self-centering carbide tip improves cut speed and accuracy when starting holes in masonry.
• Extended length (16 in flute, 18 in overall): Lets users reach deep drill depths without extensions or multiple passes for through-works.
• Optimized flute design: Fast material ejection reduces heat build-up and helps the bit run cooler during extended drilling.

Who It's For

This bit is aimed at masons, framing crews, and experienced DIYers who frequently drill large holes in concrete, block, brick, or stone and who use SDS Plus rotary hammers. It is most useful where one long, aggressive bit reduces downtime compared with shorter bits and where carbide cutting and chip clearance are priorities.

Those who rarely drill masonry, need metric sizes, or require extreme side-loading resilience should look elsewhere; a hardened specialist or thicker-shank industrial bit may be a better choice for abusive, off-axis use.

Pros & Cons

Pros

• Large 1-1/8 in cutting diameter for anchor and sleeve holes in concrete and block.
• Carbide-tipped, self-centering tip yields quicker starts and consistent hole quality.
• Optimized 2-flute design clears chips well and helps keep the bit cooler during long runs.

Cons

• Some users reported mixed durability and occasional wobble when misused or subjected to side loading; careful alignment and steady feed are important.
