## Summary description

FORTIS ER20 collet with 3 mm inner diameter, designed for ER20 chuck systems. Provides concentric clamping of round tools and tool shanks for milling, drilling and machining operations.

## Long description

FORTIS ER20 Ø3 mm collet is a precision tool-holding component intended for ER20 chuck systems. With a 3 mm inner diameter, this collet provides concentric clamping of round tools and tool shanks used in milling, drilling and general machining. It is compatible with ER20 holders and is designed to deliver repeatable, secure fixation in both CNC machines and manual equipment.
Advantages
This ER20 collet offers high concentricity and stable clamping for small-diameter cutters, drills and tool shanks. Its hardened and ground construction ensures long service life and consistent gripping force, reducing runout and vibration during rotational operations. The design supports easy insertion and removal of tools while maintaining repeatable positioning for serial or single-part machining tasks.
Suitable for
Clamping 3 mm round cutters, drills and reamers in ER20 systems
Precision milling and drilling in CNC and manual milling machines
Toolholding for small-diameter operations in metalworking and woodworking
Fixture for repeatable tool changes in production and prototyping
Key specifications
Collet type: ER20
Inner diameter: 3 mm
Function: concentric clamping of round tool shanks
Compatibility: ER20 chuck/holder systems
Application: milling, drilling and general machining
Material/finish: hardened and ground steel (typical for ER collets)
How to use
Insert the collet into a compatible ER20 nut or holder and position the tool shank so that it seats fully in the collet bore. Hand-tighten the nut to hold the tool in place, then tighten to the recommended torque for your holder using the appropriate wrench to ensure secure clamping. After machining, loosen the nut and remove the tool and collet as required. Regular inspection of the collet bore and holder surfaces for wear or contamination helps maintain concentricity and grip quality.
Usage recommendations
Use a collet-specific cleaning brush and compressed air to remove chips and coolant before assembly. Avoid over-tightening beyond manufacturer torque limits to prevent collet distortion. Replace the collet if you observe excessive runout, slipping of tools, or visible wear to preserve machining accuracy and safety.
