ER25 collet 13 mm – secure clamping of larger diameters with optimal compensation in a balanced system
The ER25 collet with a clamping range of 12-13 mm guarantees stable clamping of tools at the upper end of the medium-diameter range used for machining machine parts and structural components. Hardened 65Mn steel construction with a hardness of 44-48 HRC and compliance with DIN 6499 ensure a maximum radial runout of 0.015 mm. A clamping capacity of 1 mm allows versatile fitting of tools with similar shank dimensions.
Key advantages of the ER25 13 mm collet
- Maximum radial runout of 0.015 mm according to DIN 6499 – precision that guarantees a high-quality finish when machining parts with tight tolerances
- Clamping range of 12-13 mm with a tolerance of 1 mm – greater flexibility in tool selection than compact ER20 and ER11 systems
- ER25 construction measuring 26×34 mm – optimized proportions that provide effective vibration damping while maintaining moderate mass
- 65Mn spring steel hardened to 44-48 HRC – material with consistent properties over many years of intensive use
- Full compliance with ISO 15488 – trouble-free interchangeability with holders from reputable 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 13 mm diameter is a common size for tools intended for machining medium-sized industrial parts. The ER25 system offers a range of 1-16 mm, bridging the gap between compact ER20 and reinforced ER32 while maintaining a clamping capacity of 1 mm that exceeds smaller systems. The choice of production facilities that value reliable, versatile clamping solutions.
Frequently asked questions
Used to secure end mills, twist drills, machine taps, reamers, and other tools with straight shanks within the 12-13 mm range. A clamping capacity of 1 mm allows mounting of shanks with slightly different diameters.
The ER25 design, measuring 26×34 mm, has significantly greater mass and rigidity than ER20, which measures 21×31 mm. The 13 mm size corresponds to the upper end of the ER20 system range, while in ER25 it falls in the middle of the range, ensuring optimal interaction with the tool holder.
The miniature ER11 measures 11.5×18 mm, the common ER16 measures 17×28 mm, the medium ER20 is defined by dimensions of 21×31 mm, the intermediate ER25 has a size of 26×34 mm, the reinforced ER32 is identified by dimensions of 33×40 mm, and the industrial ER40 is distinguished by dimensions of 41×46 mm. The system designation is marked on each collet body in accordance with the requirements of DIN 6499.
