## Summary description

FORTIS ER25 collet sized for Ø14–13 mm workpieces, manufactured to DIN 6499 standard. Designed for use in ER25 tool holders and spindles to secure cutters, drills or milling tools with diameters within the specified range. Provides concentric clamping for machining operations, suitable for general milling, drilling and precision metalworking where DIN 6499 compatibility is required.

## Long description

FORTIS ER25 collet for Ø14–13 mm workpieces, produced to DIN 6499 specification. This precision tool holder element is intended for use in ER25 collet chucks and spindles, offering concentric clamping of cutters, drills and milling tools within the 14–13 mm range. It is suitable for machining operations that require reliable axial alignment and repeatable clamping accuracy where DIN 6499 compatibility is required.
Advantages
The collet provides precise radial runout control and stable tool retention thanks to its exacting manufacture to DIN 6499 tolerances. Its tapered design ensures even distribution of clamping force around the tool shank, reducing vibration and improving surface finish. The component is compact and compatible with standard ER25 systems, enabling straightforward interchangeability and predictable performance in general milling, drilling and precision metalworking setups.
Suitable for
Securing end mills, drills and reamers with 14–13 mm shank diameters
General milling and drilling operations in metalworking
Precision setups requiring DIN 6499-compatible ER25 collets
Machine shops and CNC spindles using ER25 collet chucks
Key specifications
Collet type: ER25 series sized for 14–13 mm range
Clamping range: Ø14–13 mm
Standard: manufactured to DIN 6499 dimensional and tolerance requirements
Material characteristics: hardened and ground surfaces for wear resistance and concentricity (as typical for precision collets)
Compatibility: fits ER25 collet chucks and spindles designed for DIN 6499 collets
How to use
Insert the collet into the ER25 collet nut or chuck body and ensure it seats correctly in the tapered bore. Slide the tool shank into the collet to the required depth, then assemble the nut and hand-tighten to align the tool. Use the appropriate torque with a wrench to securely clamp the tool, taking care not to exceed the recommended tightening force for ER25 systems. After clamping, verify radial runout and tool projection before starting the machining cycle. For tool changes, loosen the nut, extract the tool and remove the collet as needed for replacement.
Usage recommendations
Inspect the collet and tool shank for burrs or contamination before use, and clean contact surfaces to maintain clamping accuracy. Use proper tightening torque for ER25 nuts and periodically check runout during production runs. Store collets in a protective rack to avoid damage to the taper and maintain consistent performance.
