PERMON offers a broad range of handheld working tools, with the highest level of quality. Shank steels are produced to ISO 1180. The different variant-types have a precise fit in the hammer chuck, transmitting energy optimally with enormous stability. You can set them to work on the toughest job sites and for the most complex applications. The working tools are manufactured from low-carbon steel, combining the benefits of a hardened case without the risk of core brittleness. With a softer core, the working tools provide optimum resistance to bending stresses that typically occur with handheld powerful breakers.
