ER 11 Collet 4008 E — ER 11 collet, 1 mm clamping diameter, TECWERK

The ER 11 Collet 4008 E is a precision clamping sleeve designed for secure holding of small-diameter tools in milling and drilling setups, compatible with standard ER 11 collet chucks.

• DIN 6499-B compatible for standardised fit
• Held over full clamping length for stability
• Runout repeatability 5 µm for high accuracy
• 1 mm clamping diameter for micro tooling

Consistent precision for fine-tooling tasks

The collet offers exceptional concentricity, with a specified runout/repeatability of 5 µm, which reduces vibration and improves surface finish on small components. Because the sleeve is held along the full clamping length, the tool is stabilised over a greater contact area, lowering the risk of chatter and extending cutter life. These technical characteristics translate into fewer rejected parts and predictable machining results when working with small-diameter cutters and drills.

Easy integration with ER collet systems

Manufactured to DIN 6499-B dimensions, this clamping sleeve fits conventional ER 11 chucks without the need for intermediate sizes. The design permits clamping on the lead chamfer, offering flexibility when tools have shortened grip lengths or stepped shanks. This compatibility makes it straightforward to implement the collet into existing setups while maintaining the integrity of the toolholding system.

Compact form for dense tool arrangements

With a length of L 18 mm and an outer diameter of D 11.5 mm, the collet is suited to tight spindle spaces and multi-tool arrangements. The 1 mm clamping diameter and the specification that the clamping range bridges nominal minus 0.5 mm explain how slight undersize can be compensated, enabling secure holding of tools that are marginally under nominal size. This compactness supports higher spindle counts and closer tool spacing without sacrificing clamping reliability.

FAQ

What tolerance can be expected for concentricity with this collet?
The stated runout/repeatability for the TECWERK ER 11 collet is 5 µm, which provides tight concentricity for small-diameter tooling.

Will this collet fit existing ER 11 chucks?
Yes; the sleeve is produced to DIN 6499-B and is compatible with standard ER 11 collet chucks.

Can tools with short shank lengths be clamped securely?
The design allows clamping on the lead chamfer, so tools with reduced clamping length can still be held reliably.

How does the clamping diameter bridging specification affect tool selection?
The bridging value (nominal minus 0.5 mm) indicates the collet’s capacity to compensate for slight undersize, aiding secure grip on tools marginally under nominal diameter.

What are the physical dimensions to check for spindle clearance?
Key dimensions are L 18 mm and D 11.5 mm; verify these against the spindle and toolchanger envelope for compatibility.
