ETM is a brand specialising in the production of precision spring collets and robust clamping systems for mechanical machining. Ideal for milling, drilling, turning and CNC applications, they guarantee stability, low vibration and quick tool changes.
Product Range
- ER Spring ColletsAvailable in the ER11, ER16, ER20, ER25 and ER32 series. They offer precise and uniform clamping, with a tolerance of ±0.5 mm, ideal for milling, drilling and threading tools.
- DIN 6499/ER SpindlesThey allow the secure clamping of cylindrical tools. Guaranteed for high concentricity and compatibility on CNC systems and machine tools.
- Shrink-Fit ColletsThermal fitting system that ensures perfect concentricity, high rigidity and extended tool life. Ideal for high-speed machining.
- Weldon ColletsDesigned for heavy-duty milling applications: enhanced clamping thanks to the Weldon surface and robust tool holders.
- Tapping collets With axial compensation, they guarantee thread precision and reduce the risk of tap breakage.
