KAUFMANN Set of 8 mm drill bits for dry drilling into ceramics and concrete (Ref. 26.901.11)

A special set of Kaufmann drill bits with a diameter of 8 mm includes a drill bit designed for dry drilling of hard but brittle materials, such as ceramic tiles up to hardness level 9 or glass . Thanks to the use of tungsten carbide and a special drill bit edge, it is suitable for very precise drilling without the need for additional cooling. It is recommended to drill at a maximum of 200 revolutions per minute without hammer action. The second drill bit is designed for precise drilling into concrete. The drill bits are sold in a plastic case.
