ER25 15 mm collet – stable clamping of large tools using the full range of the intermediate system
The ER25 collet with a 14-15 mm range provides secure clamping of tools with large shank diameters near the upper limit of the system range. Hardened 65Mn steel construction with a hardness of 44-48 HRC, combined with compliance with DIN 6499, ensures a maximum radial runout of 0.015 mm. A collapse range of 1 mm guarantees flexibility in tool selection unavailable with smaller ER systems.
Key advantages of the ER25 15 mm collet
- Maximum radial runout of 0.015 mm according to DIN 6499 – positioning accuracy essential for precision roughing and finishing
- Clamping range of 14-15 mm with a tolerance of 1 mm – allows large tools to be used in the second-highest size range of the system
- ER25 design with overall dimensions of 26×34 mm – increased mass ensures effective vibration reduction during heavy cutting
- 65Mn spring steel hardened to 44-48 HRC – durability that guarantees stable performance over many years of service
- Compliance with the international ISO 15488 standard – full interchangeability with holders from leading CNC machine tool manufacturers
This collet is designed to hold end mills, twist drills, machine taps, and reamers used to machine structural steels, aluminum alloys, and engineering plastics. The 15 mm diameter is among the sizes used for tools intended for heavy machining of industrial components requiring substantial stock removal. The ER25 system with a 1-16 mm range accommodates this diameter without switching to the larger ER32 system, optimizing toolroom equipment costs. A proven solution for manufacturing plants machining medium and large workpieces.
Frequently asked questions
It secures end mills, twist drills, machine taps, reamers, and other tools with straight shanks in the 14-15 mm range. A tolerance of 1 mm allows shanks with slightly different diameters to be fitted.
The ER25 system covers diameters from 1 to 16 mm, fully accommodating the 15 mm size without requiring the larger ER32. The 26×34 mm size guarantees adequate rigidity for this diameter, while the compact dimensions facilitate machining in confined workspaces.
The smallest ER11 measures 11.5×18 mm, the common ER16 has overall dimensions of 17×28 mm, the medium ER20 measures 21×31 mm, the intermediate ER25 measures 26×34 mm, the reinforced ER32 has overall dimensions of 33×40 mm, and the industrial ER40 measures 41×46 mm. The system designation appears on each collet body as required by DIN 6499.
