Canela tooling systems: antivibratory end mill and shell mill adaptors, mill adaptors and milling cutter arbors, cylindrical modular shanks and ER20 center drill holders. CAT, DIN 69871-A, JIS B 6339-BT and HSK Form A tapers. Every page lists the taper, the head thread and the clamping torque, so you can match the adaptor to the modular head you already run.
