1-1/4 in x 18 in SDS Plus Rotary Hammer Drill Bit - Long Masonry

In this review the 1-1/4 in x 16 x 18 in SDS Plus rotary hammer drill bit is evaluated as a specialist tool for heavy masonry work where a deep, clean hole is required. The bottom line: this bit is best for tradespeople and serious DIYers who need a long, carbide-tipped bit that can bore through brick, stone, concrete and block without frequent replacement. The review finds the bit offers strong cutting performance and good value for the price, although users should be mindful of proper hammer drill compatibility and technique to avoid wobble or premature bending.

Key Features

• SDS Plus compatibility: Works with any SDS Plus rotary hammer, making it easy to swap between common brands on the jobsite.
• Carbide tipped 2-flute head: The self-centering carbide tip provides faster cut speeds and helps begin holes cleanly in masonry surfaces.
• Extended length: The 16 in working length and 18 in overall size let users drill deep holes without switching to extensions.
• Optimized flute design: Two flutes are shaped to eject material quickly, which reduces clogging and helps the bit run cooler during sustained drilling.
• Masonry focus: Specifically designed for brick, stone, concrete and block, so users get a purpose-built bit rather than a general-purpose alternative.

Who It's For

The bit is aimed at professionals and experienced DIYers who frequently drill deep holes in masonry for anchors, through-runs or plumbing and electrical passthroughs. Its long length and carbide tip make it a practical choice for jobs where a standard bit would be too short or wear out quickly.

It is not the best fit for casual users who rarely drill concrete or for those working with SDS Plus alternatives; users who require extreme bending resistance on very thin or misaligned setups should consider shorter, heavier-duty masonry bits or different tool setups to reduce wobble risk.

Pros & Cons

Pros

• Strong drilling performance in concrete and block thanks to the carbide tipped, self-centering head.
• Long reach eliminates the need for extensions on many deep-hole tasks.
• Efficient material ejection keeps the bit cooler under continuous use.

Cons

• Some users report wobble or bending if used without a steady setup or when the bit is subjected to side loads during use.

Specifications

Our Verdict

The 1-1/4 in x 18 in SDS Plus rotary hammer drill bit is a solid value for those who need a long, carbide-tipped masonry bit that drills clean, deep holes.
