HSK (hollow taper shanks) HSK-toolholders DIN 69893 The hollow taper shank (HSK) has become popular since its standardization as an interface between machine spindle and tool. DIN 69871 HSK benefits to the user include: •  High static and dynamic rigidity ISO 60 •  High precision axial and radial reproducibility •  High tool change accuracy and repeatability •  High speed machining performance •  Short tool changing times •  Coding and identification •  Coolant feed MA S 403 BT DIN 2080 Balancing recommendations and r.p.m. limits Pramet HSK-toolholders are generally pre-balanced to G 6.3/15,000 rev./min. Fine balancing on request is possible. HSK-A Because  the  rotational  speed  is  the  largest  following  r.p.m.  limits  for  HSK  interfaces  have  influencing factor together with the limits regar- been recommended as guidelines within the HSK ding the spindle or spindle bearing interface, the  standards: HSK-A 63 to 25,000 rev./min HSK-A 100 to 16,000 rev./min VDI Depending on the tool, it may be necessary to if machine and spindle manufacturers are taken into balance both the tool holder and tool when applying consideration and it is possible to define tools and the maximum r.p.m. Exact limits can only be deter mined projecting lengths.
