Diamond core drill bit RM-TX 052x300-4x1 1/4 UNC 10170429020

Drilling in reinforced concrete without water cooling

The RM-TX diamond core drill bit with a diameter of 52 mm is a tool designed for extreme working conditions. Drill bits from this series excel where traditional methods fail - namely when drilling through heavily reinforced concrete walls in dry mode. The inability or lack of necessity to use water cooling is not an obstacle. The construction based on diamond segments with oriented diamonds and an efficient bond allow for maintaining a high drilling speed even during intense contact with reinforcement.

Construction and diamond segments

The working segments have a turbo shape, which is not accidental - this profile accelerates debris removal and reduces the risk of the core clogging. Oriented diamond in the segment means that the crystals are directionally arranged, maximizing their cutting effectiveness while working in concrete. The working length of 300 mm allows for making through-holes in standard structural walls without the need to interrupt work or extend the tool. The 1¼ UNC thread shank ensures compatibility with commonly used handheld core drill machines equipped with a micro-hammer function.

Operating mode and efficiency

Dry drilling technology eliminates the need to connect a water installation, which significantly simplifies construction site logistics - especially inside buildings, where moisture would be a problem. The core drill machine with micro-hammer function delivers impact energy directly to the cutting edge, accelerating the drill bit's progress even in the hardest parts of reinforced concrete. The RM-TX series includes diameters from 42 to 152 mm, so this specific 52 mm diameter model represents the middle of the scale - it is suitable for both electrical cable routing and installation pipes.

Application and compatibility

The drill bit is intended for two main types of substrate: unreinforced concrete and reinforced concrete. This versatility makes it effective for both finishing works and structural penetrations requiring passage through reinforcement layers. Before purchasing, it is worth ensuring that your core drill machine supports the 1¼ UNC shank - this is a standard thread used in heavy construction equipment, but smaller devices may require an adapter.
