Hoffmann Group 47 The hollow shank interface HSK - Forms and features Note: See page 673 for information on ISO taper (SK) - interfaces. Taper hollow shanks for automatic tool change IS012164-1 (DIN69893-1 FormAand FormT) DIN 69893 Used for machining centres, milling machines, special machines with automatic tool change. Pipe for central axial coolant feed. Torque transmission by 2 driving slots at the end of the taper. For Form T, the tolerance (dimension b5) is narrowed. 2 collar grooves for tool magazine, positioning notch. Bore for data carrier DIN 69 873 in collar. DIN 69893-2 Form B din 69893 With tool gripper groove Used for machining centres, milling machines for rough machining, lathes. With enlarged collar and position notch. Decentralised coolant supply via the collar or central supply via the coolant pipe. Torque transmission by 2 collar grooves. Bore for data carrier DIN 69873 in collar. Taper hollow shanks for manual tool change IS012164-1 (DIN 69893-1 FormC) DIN 69893 DIN 69893-2 Form D DIN 69893 Preferred for use on spindles in transfer lines and special machines without automatic tool change or stub drill spindles and tool extensions / reducers. Central axial coolant feed. Torque transmission by 2 driving slots at the end of the taper. Used in all areas which require a large flat face for even better support during manual tool changing. With enlarged collar. Decentralised coolant supply via the collar or central supply via the coolant pipe. Torque transmission by 2 collar grooves. Taper hollow shanks for higher speeds (HSC) Prelim standard (DIN 69893-5 Form E) DIN 69893 Used for high frequency spindles, woodworking machines. Rotationally symmetrical, without driving slot. Torque transmission by friction. Pipe for central coolant feed. E-DIN 69893-6 Form F DIN 69893 With reduced taper. With tool gripper groove The HSK i nterface has the following advantages compared to the ISO taper: High repetition accuracy when changing tools. Fixed axial positioning due to flat face. Suitable for high-speed cutting. No pull-studs required. Material: Special steel for highly demanding requirements. Surface hardness: 58-62 HRC. Tensile strength at core at least 1000 N/mm2.
