Diamond core drill bit RM-TX 062x450-5x1 1/4 UNC 10170085490

Drilling in reinforced concrete without water – and quickly

The RM-TX drill bit operates without water cooling, making it the ideal solution where moisture is prohibited – when drilling in existing structures, near electrical installations, or in locations without water access. You don’t need to worry about leaks, splashes, or surface damage – this tool works dry.

Diamond segments with oriented diamond grains (DiaFIX technology) and their turbo shape ensure consistent, high drilling speed even in the toughest materials. This isn’t just about “faster” drilling – it’s about achieving significantly faster hole formation at the same drill motor power compared to standard core bits. That means less working time and reduced battery consumption on cordless drills.

Designed for drills with micro-impact – and only for them

This is not an ordinary bit for a standard hand drill. It is engineered to work with tools equipped with micro-impact mechanisms – Eibenstock, Baier, Cardi, Milwaukee. It performs best precisely with this type of mechanism: the impacts help fracture the concrete while the diamonds continuously cut on freshly exposed surfaces. If speed drops – temporarily turn off the vacuum and continue drilling. The segments automatically re-sharpen themselves.

What to remember?

• 62 mm diameter and 450 mm length is the standard combination for pipe and cable openings – large enough to avoid additional enlarging.
• The 1¼ UNC shank is universal – compatible with most micro-impact hand drills on the market.
• At 3 kg, this is not lightweight – but this results from the material density and bit length. This is not a tool for prolonged overhead use.
• Use copper or bronze rings during installation – they facilitate removal of the bit from the spindle after work.

There’s no room for compromise: if you need a hole in reinforced concrete without water cooling, this is one of the few solutions that actually works.
