ER32 16 mm collet – secure clamping of large shanks in a system with the highest grade of industrial rigidity
The ER32 collet with a range of 15-16 mm provides secure clamping of tools with large shank diameters in a system offering exceptional resistance to dynamic loads. Manufactured from hardened 65Mn spring steel with a hardness of 44-48 HRC in accordance with DIN 6499, it ensures radial runout not exceeding 0.015 mm. A collapse range of 1 mm allows flexible tool mounting within the specified dimensional range.
Key advantages of the ER32 16 mm collet
- Maximum radial runout of 0.015 mm according to DIN 6499 – positioning accuracy essential for demanding machining of components with tight dimensional tolerances
- Clamping range of 15-16 mm with a tolerance of 1 mm – flexibility to mount tools with slightly different cylindrical shank diameters
- Robust 33×40 mm construction ensuring exceptional stability – effective vibration reduction during intensive machining with large-diameter tools
- 65Mn steel hardened to 44-48 HRC – reliability that maintains consistent clamping properties over many years of industrial service
- Compliance with ISO 15488 – full interchangeability with chucks from renowned tooling system manufacturers on the market
The collet is designed to secure end mills, twist drills, machine taps, and reamers used for machining structural steels, aluminum alloys, and cast irons. The 16 mm diameter is among the largest commonly used shank sizes, used for intensive stock removal from industrial workpieces. The ER32 system, with dimensions of 33×40 mm, exceeds the smaller ER11, ER16, ER20, and ER25 systems in mechanical rigidity, providing the best vibration damping during heavy cutting operations. A professional solution for facilities performing rough machining of large machine components.
Frequently asked questions
Ideal for rough milling, deep-hole drilling, and tapping in structural steels, aluminum alloys, and cast irons. A shank diameter of 16 mm ensures the rigidity required for intensive material removal.
The ER32 design, with dimensions of 33×40 mm, has significantly greater mass and rigidity than ER20 or ER25 systems. Its more robust construction reduces vibration more effectively during heavy machining, protecting tools and improving surface finish quality.
The miniature ER11 is identified by its 11.5×18 mm dimensions, the general-purpose ER16 measures 17×28 mm, the versatile ER20 is identified by its 21×31 mm size, the intermediate ER25 measures 26×34 mm, the industrial ER32 is defined by its 33×40 mm dimensions, and the largest ER40 measures 41×46 mm. The system designation is marked on the collet body in accordance with the requirements of DIN 6499.
