Round file for manual sharpening of saw chains with precise spiral cut for outstanding sharpness and particularly long tool life. For fast, score-free sharpening of saw teeth. In comparison to machine sharpening, these files remove stock sparingly without thermalloads due to friction on the metal.
- POLISTAR flexible tools have been especially developed for work on the inner surfaces of holes and pipes. - Advantages: - Optimum adaptation to contours thanks to high flexibility. - Most effective work on small inner diameters, particularly in the range of 7–40 mm, due to tool dimensions.
