3/4 in x 39 in SDS Plus Rotary Hammer Drill Bit - Long Masonry Reach

In this review the Sabre Tools 3/4 in x 37 x 39 in SDS Plus rotary hammer drill bit is evaluated for masons, remodelers, and DIYers who need a long, reliable bit for deep anchors or passing wiring through thick masonry. The bottom line: this is a purpose-built, long masonry bit that delivers consistent drilling through brick, block, stone, and concrete thanks to its carbide tipped self-centering head and two-flute design. Its length and chip-clearing geometry are the single biggest reasons to choose it when reach and durability matter.

Key Features

• Length and reach: The 39 in overall length with a 37 in working section lets users drill deep holes through thick walls or stacked block without joining extensions.
• SDS Plus compatibility: The SDS Plus shank fits most common rotary hammer drills from major brands so it is easy to use with existing tools.
• Carbide tipped, 2-flute head: The self-centering carbide tip and two-flute geometry improves cut speed and helps maintain accuracy when starting and progressing through masonry.
• Optimized chip evacuation: The bit profile is designed to move debris out of the hole efficiently, reducing heat buildup and extending bit life during extended drilling runs.
• Broad masonry use: Built for brick, stone, concrete and block, it is suited to a variety of common jobsite materials without sacrificing performance.

Who It's For

This bit is aimed at contractors, electricians, and serious DIYers who need to drill deep or hard-to-reach holes in masonry - for example through cinder block walls, brick chimneys, or thick concrete where a short bit would be inadequate. The long length removes the need for multiple connected extensions and reduces wobble compared with improvised setups.

Those who only make occasional shallow holes in soft materials or who do not own an SDS Plus rotary hammer should look elsewhere; a shorter masonry bit or standard twist bits will be more convenient and often less expensive for light duty tasks.

Pros & Cons

Pros

• Excellent reach and rigidity for deep holes in block and concrete, reducing the need for extensions.
• Durable carbide tip and two-flute design deliver fast cutting and long life on masonry tasks.
• Good value for money given build quality and length, with users reporting reliable drill accuracy.
• Compatible with the broad range of SDS Plus rotary hammers, making it easy to integrate into existing kits.

Cons

• Length makes it less convenient for tight spaces and can be overkill for shallow or occasional holes.
• As a specialty long masonry bit, it requires an SDS Plus rotary hammer; it will not fit non-SDS chuck systems.

Our Verdict
