BASIC ARBORS
HIGH RIGIDITY SHELL MILL HOLDER BIG DAISHOWA offers tool holders that are compatible with the 2015 revision of the ASME B5.50 (CAT) standard The elimination of the reduced section past the v-groove greatly improves radial rigidity for higher performance milling applications. Not all machining centers are capable of accepting the 2015 revision and caution should be taken before installing these high rigidity tool holders. Always consult your machine tool manual or the machine tool builder for information about tool change requirements.
