Sistemi Klein Z052 Tornado CNC Collet Nut Torque Wrenches – ER25, ER32, ER40 & EOC25

Sistemi Klein Z052 adjustable torque wrenches designed specifically for tightening Tornado dust and chip extraction nuts on CNC toolholders. Available for ER25, ER32, ER40 and EOC25/SYOZ25 configurations, with controlled torque adjustment, ±4% permissible deviation and an individual calibration test report.

The Sistemi Klein Z052 Tornado Torque Wrenches are specialist CNC toolholding accessories designed for the correct tightening of Sistemi Klein Tornado dust and chip extraction nuts.

The Tornado system is used on CNC machining centres to help remove dust and chips during routing and nesting operations. Correct tightening of the extraction nut is essential for maintaining secure cutter clamping while protecting the collet and toolholder from excessive tightening forces.

Unlike conventional collet nut spanners, these adjustable torque wrenches allow operators to apply a controlled tightening torque suited to the cutter diameter and collet configuration.

Key features and benefits

• Designed for Tornado extraction nuts: Specially developed for tightening Sistemi Klein Tornado dust and chip extraction nuts used on compatible CNC toolholders.

• Controlled tightening torque: Adjustable torque settings allow operators to apply the manufacturer's specified clamping torque for different cutter diameters.

• Protects cutters and toolholders: Helps avoid insufficient tightening, which can allow cutter movement, and excessive tightening, which may damage the collet or toolholder.

• Clear torque indication: Provides a distinct mechanical and audible signal when the selected tightening torque is reached.

• Manufacturer-specified accuracy: Permissible torque deviation of ±4%, according to DIN ISO 6789.

• Four toolholding configurations: Available for ER25, ER32, ER40 and EOC25/SYOZ25 Tornado nut systems.

Each wrench is supplied with operating instructions and an individual calibration test report, making it a practical addition to CNC tool-changing stations and production workshops.
