Product details
SK collets in this catalog cover SK10, SK16, SK20 and SK25. Each family has its own body diameter, length and clamping range, so the holder designation and physical dimensions should be checked together. These pages describe the collet series only and do not establish a spindle-taper specification for a complete holder.
Clamping-size choice
Select an individual bore within the chosen SK family's catalog range.
Clear system naming
Specify SK collet series explicitly to distinguish it from other tooling labeled SK.
Specifications & model range
Dimensions are in millimeters unless otherwise stated. Confirm the final drawing before ordering.

Models and specificationsDoes SK here identify the machine spindle taper?
No. This page covers the SK collets listed in the company catalog, not a complete spindle-taper holder.
How do I distinguish SK16 from SK20?
Check the family marking, body diameter and length against the table rather than relying on appearance.
Is the listed range the capacity of one collet?
It is the family coverage. State the actual tool shank size so an individual collet can be confirmed.
Can an unmarked collet be matched?
Send measured dimensions and clear photographs of the collet and holder. The match requires confirmation before supply.
