Technical Information Technical Information HSK Shank Tools WIDIA Taper and Face Quick-Reference Identification HSK hollow-stub taper shanks are a widely used DIN standard for machine tools. HSK tools have a simultaneous 1:10 taper, which generates two surface contact areas: face and taper. Compared with traditional steep-taper shanks, HSK shanks are shorter, hollow, and clamp from the inside. They also incorporate drive keys that engage milled key-slots in machine spindles and offer higher static and dynamic stiffness than standard steep taper tooling. HSK tooling includes seven toolholder shank forms: A, B, C, D, E, F, and T. Various machine-spindle receivers are available for each. However, the choice of form depends on application requirements such as torque and spindle speed. HSK-A for general-machining service Form A HSK-B greater flange support than form A for heavier work Form A for automatic tool change is the most common shank, typically used on new machining centers and for general service. Form A has a drive slot in the small end of the tapered shank and features coolant through the center, using a coolant tube thread mount inside the shank cavity. In many applications, wrench access holes are provided through the taper as an option for manual clamping and automatic tool change shanks. Form A shanks have mounting holes for an electronic chip. There are eight different sizes of form A ranging from 32-160mm (1.260-6.299") flange diameter. Form B Form B is also for automatic tool change. It is similar in appearance to form A but dimensionally different. Form B provides greater flange support for heavy machining, even though its taper shank size is smaller than form A. This style of shanks have drive slots in the flange and drive keys in the taper. Coolant for form B is fed through ports in the flange. Mounting holes for an electronic chip are also a feature of form B. For form B there are seven different shank sizes from 40-160mm (1.575-6.299") flange diameter. HSK-C similar to form A but for manual tool change applications Forms C and D Forms C and D for manual tool changes are variations of forms A and B, but the gripper groove and chip holes are eliminated. These two forms always have their access holes through the taper for manual clamping. These manual forms are typically used on transfer lines and non-rotating applications for NC lathes. HSK-D similar to form B but for manual tool change applications There are six different shank sizes for form C ranging from 32-100mm (1.260-3.937") flange diameter. Form D has five different shank sizes from 40-100mm (1.575-3.937") flange diameter. (continued) K46 WIDIA
