## Summary description

FORTIS ER40 collet for toolholding with 16 mm nominal diameter and 15 mm clamping length, manufactured to DIN 6499 standard. Designed for securing cylindrical shank tools in ER40 collet chucks and spindles, it provides concentric clamping for milling, drilling and turning operations. Suitable for workshop and CNC applications requiring reliable tool grip.

## Long description

FORTIS ER40 Ø16 mm collet with a 15 mm clamping length is a precision toolholding accessory manufactured to DIN 6499 standard. It is intended to secure cylindrical shank tools in ER40 collet chucks and compatible spindles, providing concentric clamping for milling, drilling and light turning operations. The collet's nominal diameter of 16 mm and extended 15 mm clamping length offer secure engagement of the tool shank while maintaining alignment and repeatability during machining.
Advantages
This ER40 collet delivers accurate radial runout control and stable clamping force for consistent machining results. Manufactured to DIN 6499 tolerances, it ensures interchangeability with standard ER40 chucks and retention systems. The 15 mm clamping length increases contact area with the tool shank, improving grip and reducing the likelihood of slippage under moderate cutting loads. The collet's design supports easy installation and removal using conventional collet nuts and wrenches.
Suitable for
 Securing 16 mm cylindrical shank end mills and drill bits in ER40 collet chucks
 CNC milling and drilling operations requiring concentric tool clamping
 Workshop toolholding for small- to medium-sized machining tasks
Key specifications
 Collet type: ER40 (DIN 6499 compliant)
 Nominal diameter: 16 mm
 Clamping length: 15 mm
 Application: cylindrical shank tool clamping in collet chucks and spindles
 Material and finish: precision-ground metal suitable for machine tool environments
How to use
Insert the tool shank into the collet until it seats flush or to the desired insertion depth, then place the collet into a compatible ER40 collet nut and thread the assembly into the collet chuck or spindle nose. Tighten the collet nut to the manufacturer's recommended torque using the appropriate spanner or tightening tool to achieve secure clamping. For removal, release the nut and withdraw the tool; inspect the collet and tool shank for wear or damage before reassembly.
Usage recommendations
Use this collet with ER40 chucks and spindles that comply with DIN 6499; regularly inspect the collet for wear, clean mating surfaces to remove chips and coolant residue, and avoid over-torquing the collet nut to preserve clamping accuracy and service life.
