Diamond dry core drill bit

Very cost-effective

The newly developed diamond bond ensures optimum drilling speed and service life with a simultaneously broad application range -> One core bit for a wide range of different construction materials.

Special laser welding process

For optimal segment connection on the core bit body

Fast, easy tapping

Tapping with this product is easy compared with competitor products. Universally suitable tapping aids for all core bit diameters depending on the working length. Very easy to remove.

Less resistance in the material

The segments, which are approx. 10 % narrower than in competitor products, prevent unnecessary friction losses. This makes tapping easier too.

Extra-long service life

Particularly high segments compared to many competitors, enabling a significantly longer service life

Dia. 68 mm and dia. 82 mm especially for switch and junction boxes
