The hollow shank interface HSK - Forms and features Note See page 599 for information on ISO taper (SK) - interfaces. Taper hollow shanks for automatic tool change ISO 12164-1 (DIN 69893-1 Form A and Form T) DIN 69893 i Use in machining centres, milling machines, special machines with automatic tool change. Central, axial coolant supply via coolant pipe, i Torque transmission by 2 drive slots at the end of the taper. For Form T the tolerance (dimension b5) is narrowed, i 2 flange grooves for tool magazine, position notch, i Bore for data carrier DIN 69873 in collar. DIN 69893-2 Form B DIN 69893 With tool gripper groove I i Use in machining centres, heavy-duty milling machines, lathes, i With enlarged collar and position notch. Decentralised coolant supply via the collar or central supply via the coolant pipe, i Torque transmission by 2 flange grooves, i Bore for data carrier DIN 69873 in collar. Taper hollow shanks for manual tool change ISO 12164-1 (DIN 69893-1 Form C) DIN 69893 P i 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 supply. i Torque transmission by 2 drive slots at the end of the taper. DIN 69893-2 Form D DIN 69893 i Used in all areas which require a large axial plane for even better support during manual tool changing, i With enlarged collar. Decentralised coolant supply via the collar or central supply via the coolant pipe. i Torque transmission by 2 flange slots. Taper hollow shanks for higher speeds (HSC) Prestandard (DIN 69893-5 Form E) DIN 69893 E-DIN 69893-6 Form F DIN 69893 i Used for high frequency spindles, wood-working machines. Axially symmetric, without drive slots, i Torque transmission by friction. Central coolant supply possible via coolant pipe. i With reduced taper. With tool gripper groove The HSK interface has the following advantages compared to ISO taper High repeat accuracy when changing tools. Fixed axial positioning due to axial plane. Suitable for high-speed cutting (HSC). No pull-studs required. Material Special steel for heavy-duty requirements. Surface hardness 58 - 62 HRC.
