Product Details Description Specification Videos CHARACTERISTICS Supplied water cools the diamond-tipped teeth, removes dust, and increases drilling efficiency. By the automatic valve mechanism, water is fed to the cutting teeth only while drilling. Since the cutter and body are connected with a thread, simply replacing the cutter will suffice when the cutter teeth are worn. Cracks do not get clogged with dust. The backside surface breakaway is minimized after drilling. Drilling work with low noise and the least amount of vibration and impact transferred to the worker.
