TECWERK ER 32 Collet Set (470 E) — 3–20 mm range

The TECWERK ER 32 Collet Set (470 E) is a compact clamping kit for general workshop milling and turning, offering precise concentricity across a broad diameter range

• Precise runout & repeatability 5 µm
• Comprehensive 18-piece range 3–20 mm
• Delivered in durable wooden base
• Designed for ER 32 collet chucks

Keep spindle concentricity and tool life under control

Consistent concentricity is a core factor in stable machining. The set delivers a documented runout and repeatability of 5 µm, which reduces vibration and improves surface finish on turned and milled parts. In practical terms, this level of accuracy helps maintain cutter geometry and extends tool life, while also reducing rework rates on precision components. For workshops aiming to control tolerances without complex measuring protocols, the measurable concentricity performance provides an objective basis for process decisions.

One set to cover common workshop diameters

A single kit that covers a wide spectrum of sizes simplifies tooling logistics. The collets span 3–20 mm in single-millimetre steps, allowing uninterrupted operation across typical bar work and small component machining. By consolidating frequently used diameters into a complete set, machining centres and small workshops reduce changeover time and the need for ad hoc purchases. This practical coverage supports leaner inventory management and helps maintain throughput on mixed-production days.

Robust presentation that protects precision

Supplied in a wooden base, the collets remain protected and organised when not in use, which preserves the seating faces and prevents accidental knocks that can degrade accuracy. The compact footprint (150 x 30 x 190 mm) makes bench-top storage straightforward, while clear placement prevents lost items and speeds up tool changes. Maintaining an organised toolset contributes directly to uptime: less searching, fewer damaged collets and a tidier workbench mean faster setup and more consistent machining results.

Compatibility and simple integration into existing toolrooms

Designed for ER 32 systems, the set is compatible with ER 32 collet chucks and integrates seamlessly into standard spindle and toolholding arrangements. The kit supports common workshop operations in both milling and turning applications and is suitable for a wide range of ferrous and non-ferrous workpieces where ER 32 clamping is specified. For buyers seeking a pragmatic balance between accuracy and usability, this collet assortment offers a straightforward route to repeatable clamping without specialised fixtures or complex changeover procedures.
