Reduction sleeves for Power milling chucks
Knowing that Power milling chucks (HKS) are available in only few diameters: reduction sleeves for HKS allow to
clamp several tool shank diameters and types into a same chuck.
These reduction sleeves are specifi c for HKS, as different in dimensions and tolerances from existing reduction
sleeves, eg. the ones for Hydraulic chucks.

Reduction sleeves for HKS available sizes: see Product pages; summarized below:
- Machine sides (external diameters): diameters 20 mm & 32 mm.
- Workpiece sides (internal diameters): diameters 6 to 25 mm.
- Types (Machine side to Workpiece side): metric to metric.
- Acceptable tools shanks types, see below
Note: Tools shanks diameters tolerance: maxi h6.


Transmittable torque
For a same tool shank diameter, the transmittable torque with reduction sleeve is at least equivalent or higher compared to a direct chuck
clamping: as a result of using a bigger chuck. As bigger the chuck used, as bigger the transmittable torque.


Run-out
For chuck with reduction sleeve: Maximum run-out, at a gauge projection of 3x ØDCONWS (tool shank diameter) in relation to chuck s
machine side taper: maximum 10 µm.
Note : Direct chuck clamping: maximum 5 µm.
