Diamond core drill bit RM-TX 082x450-6x1 1/4 UNC 10170429025

High drilling speed in reinforced concrete - without water cooling

The RM-TX diamond core drill bit with a diameter of 82 mm and a length of 450 mm is a tool designed for fast drilling in heavy materials in conditions where water cooling is impossible or undesirable. The 1¼ UNC shank allows for mounting in standard handheld core drills equipped with a micro-hammer system.

Diamond segments with oriented diamonds are a key element of the design - each crystal is positioned to maximize cutting efficiency. The turbo segment shape combined with high-performance bonding ensures the tool maintains a constant drilling speed even when passing through reinforcement. Drills from this series are used without any cooling, which significantly simplifies job site logistics - there is no need to drag hoses or water tanks.

Application and compatibility

The core bit performs well in both unreinforced and reinforced concrete - where rapid hole creation for electrical cables and installation pipes is necessary. The RM-TX series includes diameters from 42 to 152 mm with lengths of 300 and 450 mm, so if you need a size other than 82 mm, DISTAR has it in their range.

The 1¼ UNC shank is the most popular standard in handheld core drills used by installers and construction crews - it fits most machines of this type available on the market.

Construction and operating parameters

The total weight is approximately 2.5 kg including the single packaging - with a core length of 450 mm, the mass is well-balanced for single-person operation during vertical ceiling and wall drilling. The manufacturer provides a user manual in PDF format.
