## Summary description

ER40 collet for toolholding, compatible with DIN 6499 standard, designed for clamping tools with diameters in the Ø18–17 mm range. Manufactured by FORTIS, this metal collet provides precision clamping for milling, drilling and turning operations where ER40 tooling is used. Suitable for use in milling spindles, collet chucks and tooling systems requiring accurate concentricity and secure grip.

## Long description

FORTIS ER40 collet Ø18–17 mm manufactured to DIN 6499 standards. This metal collet is designed to clamp tools with diameters between 18 mm and 17 mm with high radial accuracy and secure grip. It is intended for use with ER40 collet chucks, milling spindles and other toolholding systems that accept DIN 6499 style collets, providing consistent concentricity for milling, drilling and light turning operations.
Advantages
The collet offers precise and repeatable clamping within the specified diameter range, minimizing runout and improving machining accuracy. Made from hardened steel, it ensures durability under repeated tightening and cutting loads. The DIN 6499 conformity guarantees compatibility with standard ER40 chucks and spindles, facilitating fast tool changes and consistent performance. Its tapered design provides uniform radial compression for reliable holding force across the clamped tool shank.
Suitable for
 Clamping solid carbide and HSS end mills with shank diameters 17–18 mm
 Toolholding in ER40 collet chucks and milling spindles
 Precision drilling, milling and light turning operations requiring low runout
 Applications where DIN 6499 standard collets are required for interchangeability
Key specifications
 Collet system: ER40
 Clamping diameter range: Ø18–17 mm
 Standard compatibility: DIN 6499
 Material: hardened steel (metal construction)
 Usage type: precision clamping for milling, drilling, turning
How to use
Insert the ER40 collet into a compatible collet nut or chuck and ensure it seats correctly on the taper. Insert the tool shank into the collet until it contacts the bottom or reaches the desired projection, then tighten the collet nut to the torque recommended by the chuck manufacturer. After clamping, verify tool runout and axial position before starting the spindle. For removal, loosen the collet nut and withdraw the tool and collet as required.
Usage recommendations
To maintain clamping accuracy and extend service life, inspect the collet, nut and chuck taper for wear or contamination before each use; clean contact surfaces and avoid over-tightening beyond the chuck manufacturer's specified torque. Use the collet only within its specified diameter range (Ø18–17 mm) and replace it if deformation or excessive runout is detected.
