ER25 collet 14 mm – reinforced clamping of large diameters with maximum flexibility in tool selection
The ER25 collet with a clamping range of 13-14 mm provides reliable clamping of tools at the upper end of the system range intended for intensive industrial machining. Hardened 65Mn steel construction with a hardness of 44-48 HRC and compliance with DIN 6499 guarantee radial runout not exceeding 0.015 mm. A clamping capacity of 1 mm offers the greatest flexibility in tool selection among medium-sized systems.
Key advantages of the ER25 14 mm collet
- Radial runout limited to 0.015 mm in accordance with DIN 6499 – precision essential for finishing parts with tight dimensional tolerances
- Clamping range of 13-14 mm with 1 mm compensation – ability to clamp large tools while maintaining the full versatility of the system
- ER25 system dimensions of 26×34 mm – robust construction that effectively reduces vibration during intensive milling operations
- Hardened 65Mn steel with a hardness of 44-48 HRC – material durability that guarantees consistent clamping force over thousands of operating cycles
- Full compliance with international standard ISO 15488 – compatibility with holders from leading CNC machine tool manufacturers
The collet is designed to clamp end mills, twist drills, machine taps, and reamers used for machining structural steels, aluminum alloys, and engineering plastics. The 14 mm diameter is among the sizes used in tools intended for intensive machining of medium-sized industrial components. The ER25 system with a range of 1-16 mm is an optimal intermediate solution between compact ER20 and reinforced ER32, combining moderate dimensions with increased mechanical rigidity. A proven choice for production facilities requiring stable, repeatable clamping.
Frequently asked questions
Used to secure end mills, twist drills, machine taps, reamers, and other tools with straight shanks within the 13-14 mm range. A clamping capacity of 1 mm allows mounting of shanks with slightly different diameters.
The 14 mm size exceeds the maximum range of the ER20 system (limited to 13 mm) and the ER16 system (limited to 10 mm), making ER25 the most compact solution for this diameter. Its 26×34 mm size guarantees an optimal balance between rigidity and mass with a clamping capacity of 1 mm.
The compact ER11 measures 11.5×18 mm, the common ER16 has dimensions of 17×28 mm, the medium ER20 has dimensions of 21×31 mm, the intermediate ER25 is defined by its 26×34 mm size, the reinforced ER32 is identified by dimensions of 33×40 mm, and the industrial ER40 is defined by dimensions of 41×46 mm. The system designation is marked on each collet body in accordance with the requirements of DIN 6499.
