Diamond core drill bit RM-TX 132x300-10x1 1/4 UNC 10170429034

Dry drilling in heavily reinforced concrete

RM-TX series core bits excel where standard concrete drill bits fail - namely when penetrating steel reinforcement layers in structural concrete. This type of work is performed during air conditioning and ventilation installations, where large diameter holes are required in load-bearing walls and ceilings. A core drilling rig with micro-impact allows for the full potential of the tool to be utilized - the drilling speed for a through-hole in 20 cm thick M250 concrete is approximately 2 minutes. This is vital information for installation teams in multi-family residential buildings or industrial facilities.

Turbo construction with oriented diamond

The diamond segments in this bit have a turbo shape - meaning they are diagonally cut, which accelerates debris removal and reduces friction. The diamond is directionally oriented within the bond, ensuring that each part works where it is most effective. The helical flute further assists in the evacuation of dust and rubble from the cutting zone. The high-performance bond holds the diamonds so that they are exposed evenly during operation - without premature fallout or overheating.

Application and mounting compatibility

A diameter of 132 mm and a working length of 300 mm are typical dimensions for holes for ventilation pipes and air conditioning ducts. The 1¼" UNC mounting fits most drilling rigs used on Polish construction sites - both manual stationary ones and those mounted on stands. The bit is designed for dry drilling, which eliminates the need to transport water to the construction site and allows for work even in finished rooms.

Efficiency and service life

Cutting speed is a key feature of this tool - when dealing with heavy material, every minute on the construction site counts. The diamond core maintains its effectiveness over many linear meters of drilling, provided the user does not allow the tool to overheat (taking breaks during long continuous sequences). A smooth hole wall after removing the core means fewer corrections and easier installation of inserts or sleeves.
