Why Use Our Precision Expanding Mini-Collets?
  • Low Cost- Replacement collets keeps future costs to a minimum when you replace only the machinable collet.
  • Rigid Design- Long taper fit increases rigidity, allowing for heavier cuts.
  • Interchangable- Adaptor sleeves allow you to use the same expanding collet in different spindle sizes.
  • Precise- Concentricity of .0002 T.I.R. and lengths of ± .0002 obtainable for parts with closely held bores. Reassembly concentricity is excellent.
  • Miniature Work Holding- Mini Collets can grip bores down to 1/16” for light cuts.
  • Made in USA!
