8mm ER32 Collet With 6.2mm Internal Square For Threading, 15µm Runout, 40mm Length - TECWERK

Take advantage of the DIN 6499 compliance and the internal square for thread cutting together with a verified runout accuracy of 15 µm to ensure reproducible clamping and minimal rework. The compact dimensions — 8 mm clamping diameter with a 6.2 mm internal square and L 40 mm — make this collet a practical choice for integration in standard ER tooling systems; order via Metav Werkzeuge or consult the specialists for application advice.

ER 32-GB Collet – 8 mm clamping diameter, 6.2 mm internal square (TECWERK)

The ER 32-GB collet is a DIN‑compliant clamping sleeve designed for precise thread cutting and secure holding in ER-type collet chucks.

DIN 6499 with internal square for threading
Suitable for ER collet chucks and thread-cutting chucks
Runout accuracy 15 µm ensures repeatability
Compact dimensions: 8 mm clamping diameter

Consistent clamping for accurate threading and minimal scrap

The collet is engineered to meet DIN 6499 standards with an internal square for thread‑cutting tools, which reduces tool slippage and positional error during operations. With a specified runout accuracy of 15 µm, the design supports high repeatability and helps maintain thread quality across batches. For production environments where consistent geometry and reduced rework are priorities, the ensured concentricity translates directly into lower scrap rates and steadier cycle times.

Seamless compatibility with ER systems and straightforward integration

Designed as a type ER‑GB component, the sleeve mates with standard ER chucks and thread‑cutting holders, making retrofits and tool changes straightforward. The 8 mm clamping diameter and 6.2 mm internal square correspond to common thread‑cutting shank sizes, while the overall length (L 40 mm) keeps the tool‑holder assembly compact. This compatibility reduces setup complexity and supports lean tooling strategies in workshops and small production lines.

Practical workshop benefits and handling advantages

The compact form factor and defined dimensions support efficient tool storage and quick identification on the bench. The combination of a precise internal square and verified runout offers mechanical security during high‑torque operations, helping to protect both expensive cutting tools and workpiece surfaces. For maintenance planning, the uncomplicated geometry allows routine inspection with a dial indicator or a precision measuring device to confirm ongoing concentricity and service intervals.

Typical applications and target equipment

The collet suits thread‑cutting tasks and general clamping duties within metalworking and fabrication shops that employ ER collet systems. Typical users include contract workshops, toolrooms and small series production lines requiring reproducible results with standardised clamping hardware. The component’s specification supports use with thread‑cutting heads and collet chucks where precision and interchangeability are essential.

FAQ

What material is the collet made from?
The available data does not specify a material for the ER 32-GB collet; material information should be requested from Metav Werkzeuge or the manufacturer for application‑specific guidance.

Can the collet be used for other machining tasks besides thread cutting?
Yes. The ER 32-GB collet, designed for thread cutting with an internal square, is also suitable for general clamping in ER chucks where its dimensions match the tool shank.

How precise is the concentricity of the ER 32-GB collet?
The collet offers a runout accuracy of 15 µm, which supports repeatable positioning for many precision‑oriented workshop operations.

Is the collet compatible with standard ER 32 chucks?
The ER 32-GB is specified as compatible with ER‑type collet chucks and thread‑cutting holders; confirmation with the specific chuck model is recommended.

What are the exact dimensions to check before selection?
Key dimensions include the 8 mm clamping diameter, 6.2 mm internal square and L 40 mm overall length; verify these against the tool shank and holder specifications.
