1-3/16 in x 18 in SDS Plus Rotary Hammer Drill Bit - Concrete Ready

In this review the 1-3/16 in x 18 in SDS Plus rotary hammer drill bit is evaluated for contractors and serious DIYers who need a large-diameter masonry bit for through-holes in concrete, brick and stone. The bottom line: this bit is designed for fast, accurate cutting in hard materials thanks to a carbide tip and SDS Plus shank, making it a practical choice when reliability and fit in rotary hammers matter more than light hobby use. The review focuses on real-world cutting performance, build quality, and a few reported handling limits.

Key Features

• Size: The 1-3/16 in diameter and 18 in length lets users drill deep, large holes for anchors or through-runs without switching bits.
• SDS Plus shank: The standard SDS Plus shank provides a secure fit in compatible rotary hammers and quick bit changes on the jobsite.
• Carbide tip: A carbide cutting tip improves edge life and maintains drilling speed when penetrating concrete and brick.
• Steel body: A hardened steel shaft supports torque transfer and resists deformation during heavy-duty rotary hammer use.
• Masonry applications: The bit is built specifically for concrete, brick, cement and stone, so it performs best when used for drilled anchor holes and through-drilling in those materials.
• Length advantage: The 18 in overall length gives extra reach for deep or recessed drilling where a shorter bit would fall short.

Who It's For

This bit suits professional tradespeople and experienced DIYers who run rotary hammers for masonry work and need a reliable large-diameter option for anchors, sleeves or conduit runs. If you commonly drill through concrete, brick or stone and use SDS Plus tools, the size and carbide tip deliver the cutting performance and reach required.

Less suitable for casual home users who only make occasional small holes, and those using non-SDS Plus drills should look for a different shank type. Also, operators expecting perfectly vibration-free cutting should be aware that heavy loads can challenge even robust bits.

Pros & Cons

Pros

• Good drilling speed and accuracy in concrete due to the carbide tip and solid geometry.
• Secure SDS Plus fit and compatible with common rotary hammer tool interfaces for quick changes.
• Long 18 in length allows deep holes without extensions, offering practical reach on many jobs.

Cons

• One reported case of the drill bending under heavy load suggests care with excessive side pressure or using underpowered tools.
• Large diameter and length demand a powerful drill and proper technique; not ideal for light-duty cordless drivers.
