The WilTec Diamond Core Drill Bit Ø 25 mm is a high-performance, diamond-tipped tool designed for both wet and dry drilling applications.

## Description

This high-quality diamond core bit is a universally applicable aid suited for all craftsmen due to its resilience and cutting performance. The cutting bit's outstanding performance thereby allows for it to be used for both, wet and dry core drilling and is the ideal choice when drilling holes into extremely tough materials, such as granite or amoured concrete. Please note that working on materials possessing a high degree of hardness requires the application of a coolant, if there is no automatic cooling device in use. Without means of cooling the core bit while drilling, the entire project might fail and the diamond core bit get damaged in the process. Additionally it is advised to never use the drill's hammer function when working with diamond core bits as that function will greatly decrease the bit's longevity.
