SDS Plus Rotary Hammer Drill Bit 1-1/8in x 18.11in - Professional

Our review of the SDS Plus Rotary Hammer Drill Bit 1-1/8in x 18.11in finds it best suited for contractors and serious DIYers who need a robust masonry bit that holds up on hard concrete. The bottom line: this bit's tungsten carbide tip and alloy steel body deliver dependable cutting performance and longevity for drilling through concrete, brick, stone and cement walls, making it a practical choice when accuracy and wear resistance matter on larger holes.

Key Features

• Tungsten carbide tip: Provides fast cutting speeds and sustained edge life when punching through reinforced concrete and masonry.
• Alloy steel body: Adds toughness to resist bending or breaking under the torque of a rotary hammer.
• Sandblasted surface: Helps prevent rust and extends usable life in jobsite conditions where moisture and dust are present.
• 4-blade or Phillips carbide tip design: Promotes clean, accurate holes with reduced walking on the surface at startup.
• 1-1/8in cutting diameter, 18.11in overall length: Offers the reach and hole size needed for through-holes or deep anchoring in thick walls.
• SDS-Plus compatibility: Works with any SDS-Plus rotary hammer, so it fits common professional tools without adapters.

Who It's For

This bit is aimed at professional craftsmen, remodelers and experienced homeowners who regularly drill larger holes in masonry or concrete and need a durable, long-length bit that keeps cutting efficiently. It is especially useful when working on foundations, thick block walls or natural stone where a clean, precise hole is required.

Those who should look elsewhere include occasional users who only need small diameter bits or shorter lengths, and users with non-SDS-Plus tools, since an adapter or a different shank type would be necessary for compatibility.

Pros & Cons

Pros

• Durable tungsten carbide tip gives long life on hard concrete and reinforced sections.
• Sturdy alloy steel shank reduces risk of bending during heavy-duty drilling.
• Sandblasted finish helps resist rust and keeps the bit serviceable over multiple jobs.
• Good cutting accuracy and speed reported by users, even through thick foundation walls.

Cons

• Durability feedback is mixed for very extended heavy use, so heavy users may eventually need replacements.
• Only compatible with SDS-Plus rotary hammers, so not suitable for other chuck types without an adapter.
