Full Product Description
Precision Torque for Critical CNC Applications
Secure your CNC tool holders with confidence using this professional-grade adjustable torque wrench. Designed specifically for precision tightening of collet nuts and tool holder assemblies, this torque wrench ensures consistent clamping force to maximize machining accuracy, tool life, and operator safety. Incorrect torque can lead to tool holder deformation, reduced concentricity, or even catastrophic tool failure in high-speed machining - making a reliable torque wrench an essential investment for any machine shop.
Accurate & Reliable Click-Type Mechanism
Featuring a calibrated click-type mechanism, this wrench delivers an unmistakable audible "click" and tactile snap when the preset torque value is reached. This precision system prevents costly errors associated with under-tightening (tool pull-out) or over-tightening (holder damage), meeting the demanding requirements of CNC machining.
Versatile 20-220 Nm Range
The extensive torque range (20-220 Nm) provides exceptional flexibility across various machining operations. Whether working with ER collet chucks (commonly requiring 50-100 Nm for ER-20 systems) or larger tool holder assemblies, this wrench covers your needs. The 1/2" square drive with ball securing groove is compatible with a wide range of standard collet wrench sockets and attachments.
Built for the Machine Shop
Constructed from high-strength chrome-vanadium steel with multiple hardening treatments (HRC62), this torque wrench withstands daily use in harsh workshop environments. The corrosion-resistant surface protects against coolants and cutting fluids, while the ergonomic grip ensures comfortable operation during repeated use.
Quick & Easy Adjustment
Setting your desired torque is simple: unlock the adjustment ring, rotate the handle to the desired value on the clearly marked scale, and lock it in place. The quick-release button allows for fast socket changes, minimizing downtime.

Why Choose This Torque Wrench?
Protect Your Investment: Avoid costly damage to spindles, tool holders, and cutting tools by ensuring precise torque application every time.
Improve Machining Quality: Consistent clamping force ensures better tool concentricity and surface finish.
Shop Floor Durability: Built with robust materials and finishes to withstand the rigors of daily CNC operation.
Important Usage Notes
Always preset the torque before use by loosening the lock ring and adjusting to the desired value.
Ensure the wrench is perpendicular to the bolt axis during tightening to maintain accuracy.
Regular calibration is recommended (e.g., annually or after heavy use) to maintain accuracy.
Never use extension bars to exceed the wrench's torque rating
