HSK stands for \"Hohl Shaft Kegel\" - \"Hollow Shank Taper\", and as the name implies this type of interface has a cavity running through it. Unlike classical 'pull-stud' designs (CAT, BT, SK etc), HSK uses an internal drawbar mechanism which results in clamping force increasing with rotational speed. Additionally, the form features dual contact; on an axial face and the cone (1:10), which puts HSK in the upper echelons of tool holder performance.\u003c\/p\u003e\u003cp\u003eThe HSK-A form is probably the most common in the HSK family, and features drive slots which serve both to increase torque capability and provide rotational indexing (unequal slots). External features provide an interface for automatic tool change grippers and carousels. There is a bore milled directly into the side of the interface for RFID chip placement, and a threaded internal passage for coolant-through operation.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003e\u003cb\u003e\u003cu\u003e\u003cstrong\u003eCompany History:\u003c\/strong\u003e\u003c\/u\u003e\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eFamily-owned since 1977, HAIMER has grown from a precision parts specialist into a global tooling solutions supplier with operations across Europe, North America, and Asia.\u003c\/p\u003e","brand":"Haimer","offers":[{"title":"Default Title","offer_id":67502926430436,"sku":"0839359","price":427.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/1889\/files\/asset-111844-672_388c267c-6500-44d4-b989-e193388787ac.jpg?v=1791426696","url":"https:\/\/www.zedaro.com\/products\/0839359","provider":"Zedaro Inc.","version":"1.0","type":"link"}
