## Long description

The FORTIS ER20 Spring Collet for 6 to 5 mm Diameter Tools DIN 6499 is a precision-engineered accessory designed for secure and reliable tool holding in various machining operations. Manufactured by FORTIS in compliance with the DIN 6499 standard, this spring collet ensures high concentricity and a stable grip for cutting tools with diameters ranging from 6 mm to 5 mm. It is engineered to maintain consistent performance and tight tolerances during demanding milling and industrial applications.
Advantages
This ER20 spring collet offers exceptional clamping force and precise centering, which significantly minimizes runout and vibration during high-speed machining. Its robust construction ensures long-term durability and resistance to wear under continuous industrial use. The reliable grip provided by the collet contributes to improved surface finish on machined workpieces and extends the overall service life of the cutting tools.
Suitable for
Milling operations requiring secure tool retention
Machining tasks involving 6 mm to 5 mm diameter tools
CNC machining centers adhering to the DIN 6499 standard
General industrial metalworking and workshop applications
When it may not be suitable
This collet is not suitable for tools with shank diameters outside the specified 6 to 5 mm range, as using incorrect sizes can lead to poor grip, excessive runout, or tool slippage. It is also incompatible with tool holder systems that do not follow the ER20 or DIN 6499 dimensional standards.
Key specifications
Collet type: ER20 spring collet
Compatible tool diameter: 6 mm to 5 mm
Standard compliance: DIN 6499
Application: Milling and machining tool holding
How to use
To use the FORTIS ER20 spring collet, first ensure that both the collet and the corresponding ER20 tool holder are clean and free from debris or oil residue. Insert the collet into the clamping nut at an angle until it snaps securely into place, then insert the cutting tool with a shank diameter between 6 and 5 mm into the collet bore. Thread the nut onto the tool holder and tighten it gradually to the recommended torque specification using an appropriate wrench to ensure a secure and centered grip before starting the machine.
What to consider before purchase
Verify that your tool holder is compatible with the ER20 collet system
Check that your cutting tools have shank diameters strictly within the 6 to 5 mm range
Confirm adherence to the DIN 6499 standard in your existing machining setup
Usage recommendations: Regularly inspect the collet for signs of wear, contamination, or mechanical damage, and clean it after use to maintain optimal clamping precision and extend its operational lifespan.
