ER25 10 mm precision collet – accurate clamping of common diameters with 0.008 mm radial runout
The precision ER25 collet with a 9-10 mm range provides greater tool clamping accuracy than standard solutions. Its construction from hardened 65Mn spring steel with a hardness of 44-48 HRC in accordance with DIN 6499 ensures radial runout not exceeding 0.008 mm. The 1 mm collapse range provides flexibility when mounting tools within the specified size range.
Key benefits of the ER25 10 mm precision collet
- Maximum radial runout of 0.008 mm according to DIN 6499 – higher positioning accuracy grade for operations requiring tight dimensional tolerances
- Clamping range of 9-10 mm with a tolerance of 1 mm – versatility in mounting tools with slightly different cylindrical shank diameters
- A 26×34 mm design providing optimum stability – effective vibration damping while maintaining compact system dimensions
- 65Mn steel hardened to 44-48 HRC – durability guaranteeing consistent clamping properties over many years of industrial use
- Compliance with ISO 15488 – full interchangeability with holders from reputable tooling system manufacturers on the market
The collet is designed to secure end mills, twist drills, reamers, and machine taps used in machining applications requiring enhanced accuracy. The 10 mm diameter is one of the most common shank sizes offered by cutting tool manufacturers. The ER25 system, measuring 26×34 mm, offers greater mechanical rigidity than compact ER11, ER16, and ER20 systems, resulting in better vibration damping during demanding machining operations. A professional solution for facilities manufacturing components with elevated quality requirements.
Frequently asked questions
The precision version provides radial runout of up to 0.008 mm, while the standard collet allows a deviation of up to 0.015 mm. Nearly twice the accuracy enables better surface quality and tighter tolerances on machined components.
Ideal for precision finish milling, reaming holes to tight tolerances, mold machining, and manufacturing components with enhanced accuracy requirements. The 10 mm shank is one of the most common sizes used in cutting tools.
The compact ER11 measures 11.5×18 mm, the common ER16 measures 17×28 mm, the universal 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.
