CNC router spindle collets for Kress, Suhner, Mechatron

Collets for Kress and Suhner milling / routing spindles

The collets are made from high quality spring steel and has a concentricity of 0.004 mm.

Kress collets available: 2, 3, 4, 5, 6, 7, 8, 10, (12) mm and 1/8", 1/4" (1/2")

Tip: Consider using 1/8" tools if you are on a shoe string budget since they are often a touch cheaper than 3 mm shank tools.



  • UAL 23-RF (the only spindle here that can take 1/2" and 12 mm collets)
  • UAK 30-RF
  • UAD 30-RF (only available from CNC-STEP resellers)

If you frequently use different collets, we recommend using a separate cap nut for each collet to eliminate the extra step of switching back and forth.


  • Metric and imperial sizes
  • Brand specific and standard options
