Product description

HSK-A63 / HSK-A100 (HSK63A, HSK100A) DIN 69893 shrink fit chuck 4.5°, Ø3–32 mm

Shrink fit chuck with an HSK-A63 or HSK-A100 taper to DIN 69893 (ISO 12164). A cylindrical-shank tool is clamped without a collet: the heated bore of the chuck expands, the shank is inserted to the set depth, and as the chuck cools down it clamps the shank around its full circumference. The tool is removed after heating the chuck again. The clamping section has a 4.5° angle.

A shrink fit chuck requires an induction shrink fit unit: without heating, the tool cannot be inserted or removed. The shrink fit unit is not included.

HSK-A63: shank diameters from 3 to 32 mm in the standard length L = 80–115 mm depending on the diameter (Ø32: 120 mm) and in extended versions L = 120, 160 and 200 mm (Ø3–5: up to 160 mm). HSK-A100: diameters from 3 to 32 mm in length L = 85–120 mm depending on the diameter. Diameters Ø3–5 mm have no stop screw thread (G “–” in the table). Select the variant when purchasing.

Applications

  • clamping end mills, drills and reamers with cylindrical shanks, most often made of solid carbide
  • precise machining: holder runout ≤ 0.003 mm
  • high tool clamping force
  • machining in deep cavities: the slim clamping section reduces the risk of collision

d – bore diameter (tool shank), D – chuck diameter at the front face, D1 – diameter at the base of the 4.5° clamping section, L – length from the flange face (spindle side) to the chuck front face, L2 – length from the front surface of the flange to the chuck front face, L1 – maximum shank insertion depth, G – thread of the stop screw for setting the tool projection (adjustment range 10 mm), “–” – no thread and no L1 dimension.

Read the complete designation of the selected variant. For example, HSK63A-SF12-90 means an HSK-A63 taper, a shrink fit chuck (SF) for a Ø12 mm shank and length L = 90 mm; HSK100A-SF12-95 is a chuck for the same shank with an HSK-A100 taper and length L = 95 mm.

How to select

  • Check whether the spindle has an HSK-A63 or an HSK-A100 interface and select a variant with that taper: the code starts with HSK63A or HSK100A.
  • Diameter d = tool shank diameter (e.g. an end mill with a Ø12 shank = variant SF12). The shank must be cylindrical, in tolerance h6.
  • A shorter chuck gives higher rigidity, the extended one (L = 120–200 mm) gives greater reach in deep cavities.
  • An induction shrink fit unit is needed to insert and remove the tool.

FAQ

Will it fit my machine?
The holder has an HSK-A63 or HSK-A100 shank to DIN 69893 (ISO 12164), according to the variant code. Before purchasing, confirm the form and size of the spindle interface in the machine documentation. HSK-A, HSK-E and HSK-F are different shank forms, and 63 and 100 are different sizes, so the designation “HSK” alone is not sufficient to confirm the selection.

Do I need a shrink fit unit?
A shrink fit chuck requires an induction shrink fit unit: without heating, the tool cannot be inserted or removed. The shrink fit unit is not included.

Which tools can be clamped?
Tools with a cylindrical shank in tolerance h6 and with a diameter equal to d of the selected variant, most often made of solid carbide. The insertion depth must not exceed L1 from the dimension table.

How does it differ from an ER collet chuck?
A shrink fit chuck clamps the shank without a collet, around its full circumference, so it has low runout (≤ 0.003 mm) and a slim shape. An ER collet chuck covers different diameters by changing the collet and does not require a shrink fit unit.
