28940 SERIES OF MICROMOT STEEL CLAMPING PLIERS PROXXON
The Proxxon 28940 collet series is the most precise system in the Micromot line, designed to ensure perfectly concentric rotation and a stable grip of shank tools.
Made of hardened steel and featuring the typical three-segment design , they ensure uniform and reliable clamping even on the smallest diameters. They are essential for milling, engraving, and all processes requiring maximum precision.
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.
