TECWERK ER collet chuck — DIN 69871 Form AD, SK40, clamping 3–26 mm

The TECWERK ER collet chuck designed for SK40 taper spindles provides standard-compliant tool clamping for cylindrical‑shank tooling in ER collets.

• Steep taper DIN 69871 Form AD
• Clamping range 3–26 mm
• SK40 interface for widespread compatibility
• High rigidity and repeatability

Precision and process stability for milling and drilling

The ER collet chuck combines the standardised DIN 69871 Form AD steep taper with the ER collet system to deliver consistent concentricity and minimal run‑out. The chuck’s capacity to hold cylindrical‑shank tools across a 3–26 mm range makes it suitable for a broad selection of end mills and drills while keeping spindle loads stable. For production environments, this translates into fewer rejects and predictable tool life, supported by the component’s 63 mm body diameter and a projection length of 100 mm, which together enhance axial stability during cutting.

Faster setup and secure tool changes to reduce downtime

Built for compatibility with SK40 toolholders and ER40 collets, this chuck simplifies tool change routines and secures repeatable clamping force. The standard interface and familiar ER system allow rapid swapping of tooling and straightforward collet replacement, helping to shorten cycle times. The design reduces the need for frequent re‑measuring after tool changes, so machining centres and manual milling setups benefit from both efficiency gains and reduced non‑productive time.

Robust design for everyday workshop and industrial use

Made to meet workshop demands, the holder emphasises rigidity and durability under continuous use. The steep taper engagement and ER collet clamping ensure high axial and radial stiffness, which supports heavier cuts and longer engagement periods without loss of accuracy. Maintenance is straightforward: regular cleaning of taper and collet faces and routine collet inspection prevent seating issues and preserve concentricity. Delivered through Metav, this toolholding solution is backed by accessible distribution and the supply reliability expected for production use.

FAQ

What shank sizes can be clamped with this chuck?
The chuck accepts tools held in ER collets covering a 3–26 mm clamping range; collets sized to that range are used to secure the tool shank.

Is the taper compatible with standard SK40 spindles?
Yes. The product uses a DIN 69871 Form AD steep taper and an SK40 interface (connection: ER 40 / 472 E 1), making it compatible with standard SK40 toolholders.

Can this holder be used with ER40 collets?
The chuck is specified for use with ER40 collets and holds cylindrical‑shank tools in collets manufactured to DIN 6499.

What are the key benefits for production workshops?
The design provides high rigidity, consistent repeatability and a wide clamping range, which together reduce rework and help maintain stable machining processes.

How should the chuck be maintained to preserve accuracy?
Regular cleaning of the taper faces, inspection of collets for wear or deformation and correct torquing of the clamping nut keep the chuck performing within its concentricity specifications.
