The CMT TW-200 Interchangeable Torque Wrench delivers a precise 20-200 Nm torque range through a 14x18mm drive, making it the right tool for correctly tightening CNC chuck clamping nuts, including ER32, ER40, and EOC-25 collet nuts. Designed for professional woodworking and machining environments where consistent clamping force directly affects cut quality and tool life, this reversible torque wrench takes the guesswork out of fastener tension and helps prevent both under-tightening and over-tightening of critical collet assemblies.

Key Features

• 20-200 Nm torque range with 14x18mm drive - covers the full spectrum of clamping torque required for ER16 through EOC-25 collet nuts, so one wrench handles the range of CNC chuck sizes used in professional router and machining setups.
• Reversible operation - the wrench works in both tightening and loosening directions, reducing the number of tools needed at the machine and speeding up tool changes.
• Interchangeable head design - accepts TW-series hook head inserts, giving the user the flexibility to use a single wrench body across multiple collet nut sizes and dust extractor fittings rather than purchasing separate wrenches for each configuration.
• Unique calibration certificate per instrument - each wrench ships with its own individual certificate documenting verified accuracy
• Meets major international accuracy standards - meets both European and North American torque tool accuracy standards, making it appropriate for professional shops operating under either framework.
• 500mm total length - the extended handle provides comfortable mechanical advantage when applying torque to stubborn or tight collet nuts without requiring excessive grip force.
• Supplied in a protective case with instruction manual - the hard case keeps the calibrated instrument protected from shop-floor damage and makes it easy to store and transport without risking accuracy-affecting impacts.

Why This Product

• Documented, traceable accuracy for professional shops - the individually serialized calibration certificate means each wrench is verified at the unit level, not just the batch level, supporting quality management systems where torque tool documentation is required.
• One wrench body, multiple collet sizes - the interchangeable head system means shops running ER16, ER32, ER40, or EOC-25 collet nuts can standardize on a single TW-200 body and swap only the head insert, reducing tool inventory and cost.
• Consistent torque application protects tooling and workpieces - with a defined 20-200 Nm range, operators apply the correct clamping force every time, reducing the risk of collet slippage from under-tightening or thread and nut damage from over-tightening.
• Calibration meets two major industry standards - documented accuracy under both European and North American frameworks supports shops operating under either standard
