Tyrolit Stainless Steel Files - The two stainless steel files are used for pre-processing ski and snowboard edges. They ensure high material removal and precise application of the edge angle. The coarse file is a sharp and durable set-up file and is suitable for pre-processing badly damaged edges or preparing a new edge angle. The fine file is a second-cut file for processing worn edges and preparing fine tuning using TYROLIT LIFE ceramic and elastic files. They are used with the TYROLIT LIFE stainless steel angle.
