Diamond core drill bit RS-TX 052x450-4x1 1/4 UNC 10170085487

Diamond Core Drill Bit for Concrete – Dry Operation, No Cooling Required

This drill bit is designed for fast and precise drilling in reinforced and non-reinforced concrete without the need for water cooling. Ideal for situations where water access is limited—such as during installation work in existing buildings, at heights, or in areas where water spillage is prohibited.

Diamond segments with the unique DiaFix shape ensure high drilling speed, while their oriented structure effectively penetrates even dense and difficult-to-cut reinforcement. No need to apply heavy pressure or increase speed—the tool “works” on its own thanks to optimized geometry and diamond distribution.

The 1 1/4 UNC shank is compatible with most handheld hammer drills—from Eibenstock, Baier, Cardi, and Milwaukee. This means you can use it with the same equipment already in your workshop—no need to purchase new chucks or adapters.

At 450 mm in length, it allows drilling through thick walls or concrete slabs without repositioning the tool. A 52 mm diameter is standard for pipe or cable openings—particularly suitable for installing ventilation, electrical, or hydraulic systems.

No special handling required. No cooling needed. No lubrication required. Simply mount it on your drill, turn it on, and get on with your work.

The bit operates smoothly, with minimal vibration and no jumping on reinforcement—reducing the risk of tool damage and improving hole quality.
