Thanks to its resilience and high cutting performance, this high-quality diamond core bit is a universally applicable tool that is indispensable for both craftsmen and DIY enthusiasts. Thanks to its cutting performance, the core bit is suitable for both wet and dry drilling and is the ideal choice when it comes to drilling holes in extremely hard materials such as granite or reinforced concrete. When working on granite and similarly hard materials, it should be noted that a coolant should be used unless an automatic cooling device is used to ensure the success of the drilling and the longevity of the drill bit. It should also be ensured that the hammer function of the drill bit is not used when employees are using diamond core bits, as this will inevitably lead to excessive material wear.
