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

In this review the 1-1/4 in x 18 in SDS Plus rotary hammer drill bit is evaluated for professionals and serious DIYers who need a long, accurate masonry bit. The bottom line: it is a simple, purpose-built tool for drilling deep holes in concrete, brick, cement and stone where reach and cutting diameter matter. Its key selling point is the 1-1/4 in cutting diameter combined with an 18 in total length and an SDS Plus shank, which together deliver controlled, repeatable holes while working with rotary hammers designed for masonry.

Key Features

• 1-1/4 in Cutting Diameter: Provides a large clearance hole useful for anchors, sleeves or through-conduit runs where a precise wide bore is required.
• 18 in Total Length: The extended length allows deep penetration into thick walls or cores without switching to special extension systems.
• SDS Plus Shank: Ensures secure, knockout-free engagement with most rotary hammer chucks for steady drilling under hammering load.
• Steel Body with Carbide Tip: Combines toughness and a wear-resistant cutting face to maintain performance when drilling abrasive materials.
• Designed for Masonry: Intended specifically for concrete, brick, cement and stone to give predictable results on hard substrates.

Who It's For

The bit is best suited for contractors, masons and experienced renovators who routinely drill deep or wide holes in concrete and stone and who use SDS Plus rotary hammers. Its long reach and 1-1/4 in diameter make it a logical choice for jobs like installing large anchor sleeves, running conduit through thick walls, or creating clearance holes for structural fasteners.

Those who should look elsewhere include casual homeowners who rarely drill into masonry or users who need multiple diameters and shorter bits for general-purpose work. Also, operators without an SDS Plus rotary hammer will need an adapter or a different shank type.

Pros & Cons

Pros

• Customers report good drill accuracy and build quality, giving confidence on tough jobs.

Cons

• Specialized size and length make it less versatile for small everyday drilling tasks.
• Long, large-diameter drilling demands a suitable rotary hammer and technique to avoid user fatigue.

Frequently Asked Questions

Will this bit fit my rotary hammer?
It fits rotary hammers that accept an SDS Plus shank; confirm your tool uses SDS Plus before purchasing.

Can it drill rebar or metal?
It is designed for masonry; drilling reinforced concrete may be possible but performance and tool life will be reduced when encountering rebar.

Is the cutting tip replaceable?
The bit features a carbide tip integrated into the head; the product is intended as a replaceable bit rather than a serviceable tip for most users.
