ER32 collet 12 mm – secure clamping of standard diameters in a system with enhanced dynamic performance
The ER32 collet with a clamping range of 11-12 mm provides reliable clamping of tools with one of the standard shank diameters in a system offering industrial-grade structural rigidity. Manufactured from hardened 65Mn spring steel with a hardness of 44-48 HRC in accordance with DIN 6499, it guarantees radial runout not exceeding 0.015 mm. A clamping allowance of 1 mm provides versatile tool fitting across a wide range of sizes.
Key advantages of the ER32 12 mm collet
- Maximum radial runout of 0.015 mm according to DIN 6499 – positioning precision essential for accurate machining of components requiring tight dimensional tolerances
- Clamping range of 11-12 mm with a 1 mm collapse range – versatility in mounting tools with slightly different cylindrical shank diameters
- Substantial dimensions of 33×40 mm guaranteeing industrial-grade stability – effective vibration damping during intensive machining operations at higher cutting parameters
- 65Mn steel hardened to 44-48 HRC – strength that ensures consistent clamping properties over many years of use
- Compliance with ISO 15488 – full interchangeability with holders from leading tool clamping system manufacturers
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 12 mm diameter is one of the standard shank sizes commonly offered by cutting tool manufacturers. With dimensions of 33×40 mm, the ER32 system exceeds the smaller ER11, ER16, ER20, and ER25 systems in mass and rigidity, providing exceptional vibration damping at increased feed rates. A professional solution for production facilities performing intensive machining of industrial parts.
Frequently asked questions
Used to mount end mills, twist drills, machine taps, reamers, and other tools with a cylindrical shank in the 11-12 mm range. The 1 mm collapse range allows shanks with slightly different diameters to be clamped.
The ER32 design, with dimensions of 33×40 mm, has significantly greater mass and rigidity than ER25 (26×34 mm). The more robust construction reduces vibrations more effectively during machining, improving surface finish and extending tool life.
The miniature ER11 is defined by its dimensions of 11.5×18 mm, the popular ER16 by 17×28 mm, the universal ER20 by 21×31 mm, the intermediate ER25 by 26×34 mm, the industrial ER32 by 33×40 mm, and the largest ER40 by 41×46 mm. The system designation appears on the collet body in accordance with the requirements of DIN 6499.
