RM-TX 052x450-4x1 1/4 UNC diamond core drill bit 10170429021

Fast drilling in reinforced and non-reinforced concrete

This diamond core drill bit designed for dry operation enables rapid drilling of holes in heavily reinforced walls where water use is impossible or undesirable. Thanks to specially shaped turbo‑shaped diamond segments and an oriented diamond structure, the tool maintains high speed while preserving cutting precision. Ideal for installing cables and pipes in challenging construction conditions.

Key advantages

• Maximum performance – turbo segments ensure rapid material removal, reducing working time even with high-density concrete.
• Dry operation – no need for water cooling eliminates the risk of flooding installations and simplifies logistics on the construction site.
• Universal mounting – the 1 ¼ UNC shank fits most handheld hammer drills, enabling convenient use without additional adapters.
• Durability – high-quality diamond segments retain sharpness for many hours of intensive drilling, minimizing the need for tool replacement.
• Versatile range – available diameters from 42 mm to 152 mm and lengths of 300 mm and 450 mm allow selection of the optimal size for specific tasks; the 52 mm × 450 mm model is particularly recommended for large-diameter holes.

Installation and operating conditions

The drill bit is mounted directly into a handheld hammer drill equipped with micro-hammer action; simply tighten the 1‑1/4 UNC shank and begin drilling. The tool is optimized for dry operation, so no additional cooling system or specialized accessories are required. Thanks to its robust construction and precise segment bonding, the drill bit maintains stability even at high rotational speeds, resulting in uniform and clean holes.
