At Hindmechanisch, We manufacture Tool holders as per (MAS BT 403, SK DIN 69871, ISO DIN 2080,HSK DIN 69893.) We maintain Cone Tolerance as per class AT 3. Collet Chuck Run out Accuracy is maintained as per DIN 6499 norm. We maintain run out accuracy as per DIN 6358 for Shell End Mill Tool holders. Bore Tolerance for End Mill holder is maintained as H5 and run out accuracy is maintained with in as per norm DIN 6359-1.All our holders have run out accuracy and tolerance well below the specified range of DIN norms.
BT tool holders use metric thread pull studs (retention knobs). Though both standards use the same NMTB body taper, BT tool holders are symmetrical around the main spinning axis while CAT tool holders are not. That makes BT tool holders better balanced and more stable at higher speeds.
