28940 PROXXON MICROMOT STEEL COLLET SET

Micromot Precision with Three-Segment Sectioning

The proxxon 28940 collets represent the most accurate clamping system available for Micromot rotary tools. The hardened steel construction and three-segment geometry ensure a uniform grip and superior concentricity compared to traditional self-tightening chucks.

Advantages of the Micromot System

• Tempered steel: high dimensional stability and long life even under intensive use.
• Uniform tightening: the triple section distributes the force evenly around the shank.
• Maximum concentricity: ideal for milling, engraving and micro-drilling.
• Perfect compatibility: designed for Micromot tools with calibrated shanks.

Composition of the Series

Set 28940 includes:

• 6 pliers in diameters: 1.0 – 1.5 – 2.0 – 2.4 – 3.0 – 3.2 mm .
• Steel clamping ring .

Chuck or Collets?

The self-tightening chuck offers faster tool changes, but Micromot collets remain the obvious choice when maximum precision is required.

• Collets 28940: Superior concentricity, increased clamping force, ideal for milling and engraving.
• Chuck 28941: more practical for frequent changes, but less precise.

Professional tip: For technical work, PCBs, deep engraving or precision milling, always use 28940 collets to avoid vibration and deflection of the cutting edge.
