ER32 1 mm collet – maximum stability for microscopic tools in a heavy-duty industrial system
The ER32 collet with a range of 0.5-1 mm allows the smallest tools to be securely clamped in a system with exceptional mechanical rigidity. Construction from hardened 65Mn spring steel with a hardness of 44-48 HRC in accordance with DIN 6499 ensures a maximum radial runout of 0.015 mm. A collapse range of 0.5 mm ensures precise fitting of tools with minimal shank diameters.
Key advantages of the ER32 1 mm collet
- Radial runout not exceeding 0.015 mm in accordance with DIN 6499 – positioning accuracy essential for micromachining requiring the highest dimensional precision
- Clamping range of 0.5-1 mm with a 0.5 mm collapse range – allows the smallest tools to be fitted in a heavy-duty industrial system
- Large dimensions of 33×40 mm ensure exceptional stability – effective vibration elimination thanks to the substantial mass of the design, exceeding that of smaller ER systems
- 65Mn steel hardened to 44-48 HRC – durability ensuring unchanged clamping properties over many years of intensive use
- Compliance with ISO 15488 – full interchangeability with holders from the market's leading tooling system manufacturers
The collet is designed to secure micro milling cutters, precision engraving tools, miniature drills, and countersinks used to machine electronic, medical, and jewelry components. The 1 mm diameter requires particularly stable clamping due to the delicate nature of the tools and the risk of vibration damage. The ER32 system, measuring 33×40 mm, provides the highest rigidity among common ER systems, delivering exceptional vibration damping even with extremely small diameters. A professional solution for facilities specializing in precision micromachining requiring maximum dynamic stability.
Frequently asked questions
Used to mount micro milling cutters, precision engraving tools, miniature drills, countersinks, and other tools with a straight shank within the 0.5-1 mm range. The 0.5 mm tolerance allows clamping of the smallest shanks available from manufacturers.
The ER32 design, measuring 33×40 mm, has significantly greater mass than ER11, ER16, ER20, or ER25 systems. The robust construction dampens vibrations more effectively during micromachining, protecting delicate tools and improving component surface finish.
The compact ER11 measures 11.5×18 mm, the standard ER16 measures 17×28 mm, the versatile ER20 measures 21×31 mm, the intermediate ER25 measures 26×34 mm, the industrial ER32 measures 33×40 mm, and the largest ER40 measures 41×46 mm. The system designation appears on the collet body in accordance with DIN 6499 requirements.
