Since 1998, the undercarriage of the classical rail (sliding) types has taken the form of tracked, rubber wheeled and tracked fixed rail. Diamond tips have been developed in the cutters, and differences have started in the chisel geometry and arrangement, resulting in an increase of cutting efficiency. In chain saw cutters (CSC), the most important part is the chain tool assembly that does the cutting work. The hardest working and most wearing elements of the CSC machine are the cutters in the chain set, the insert holders and the chain links. In field observations and some researcher cost calculations, the related subjects and figures are given, but the reasons are not mentioned. The main problem is the alignment of the insert in the tool and the lack of arrangement on the chain. Chain saw machines are operated with more or less factory design and general operating concepts, regardless of natural stone and quarry conditions. In this paper, information about increasing the efficiency of chain arm cutters used in natural stone quarries will be presented, problems will be explained and discussed and possible solutions will be given.
