Product description

HSK-A63 / HSK-A100 (HSK63A, HSK100A) DIN 69893 hydraulic chuck, Ø6–32 mm

Hydraulic chuck with an HSK-A63 or HSK-A100 taper to DIN 69893 (ISO 12164). A cylindrical-shank tool is clamped directly in the chuck bore, without a collet: you tighten the clamping screw to the stop, and the oil in the chuck chamber expands the sleeve, which clamps the shank evenly around its full circumference (360°). The oil also dampens tool vibration. Grooves in the bore take up oil and grease residues from the shank, so the clamping surface stays dry.

A hex key for the clamping screw is needed to clamp and release the tool. No shrink fit unit or other device is required.

Available shank diameters: 6, 8, 10, 12, 14, 16, 18, 20, 25 and 32 mm, in both taper sizes. HSK-A63: length L = 70–200 mm, HSK-A100: L = 75–110 mm, depending on the diameter (dimension table). Select the variant when purchasing.

Smaller shank diameters: a chuck Ø12, Ø20 or Ø32 can clamp a smaller tool through a hydraulic reduction sleeve (Ø12: shanks 3–8 mm; Ø20: shanks 3–16 mm; Ø32: shanks 6–25 mm). Sleeves are not included with the chuck — ask about availability.

Applications

  • clamping end mills, drills, reamers and chamfering tools with cylindrical shanks
  • precise machining: holder runout ≤ 0.003 mm, better hole accuracy in drilling and reaming, even cutting of all flutes in milling and less tool wear
  • high clamping force and rigidity around the full circumference of the shank
  • vibration damping by the oil in the chuck: smoother cutting and a better workpiece surface
  • fast tool change with a hex key, no shrink fit unit needed

d – bore diameter (tool shank), D – diameter of the front clamping section, D1 – diameter of the body with the clamping screw, L – length from the flange face (spindle side) to the chuck front face, L1 – length of the front section with diameter D, L2 – bore depth from the chuck front face to the stop screw, G – thread of the stop screw for setting the tool projection (adjustment range 10 mm).

Read the complete designation of the selected variant. For example, HSK63A-HY12-85 means an HSK-A63 taper, a hydraulic chuck (HY) for a Ø12 mm shank and length L = 85 mm; HSK100A-HY12-95 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 HY12). The shank must be cylindrical.
  • Check the diameters D and D1 and the lengths L and L1 in the dimension table if the tool is to work close to walls or in a deep cavity.
  • A hex key for the clamping screw is needed to clamp and release 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.

Which tools can be clamped?
Tools with a cylindrical shank whose diameter equals d of the selected variant: end mills, drills, reamers or chamfering tools. A smaller diameter can be clamped through a reduction sleeve in a chuck Ø12, Ø20 or Ø32. The bore depth L2 is given in the dimension table.

How do I clamp the tool?
Set the insertion depth with the stop screw, insert the shank into the bore and tighten the clamping screw with a hex key to the stop. To release the tool, loosen the clamping screw.

How does it differ from a shrink fit chuck?
A hydraulic chuck does not need a shrink fit unit: the tool is clamped and released with a hex key, so a tool change is quick. The oil in the chuck also dampens vibration.

How does it differ from an ER collet chuck?
A hydraulic chuck clamps the shank without a collet and nut, evenly around its full circumference, with runout ≤ 0.003 mm and vibration damping. An ER collet chuck covers different diameters by changing the collet.
