Precision collets, pull studs, clamping nuts, and toolholders engineered for optimal machining performance
TNT Motion delivers high-precision CNC clamping tools that meet the demanding requirements of modern machining centers. Our comprehensive range includes precision collets, pull studs, clamping nuts, and toolholders manufactured to exacting European standards while offering competitive pricing through our optimized supply chain.
Whether you operate high-speed machining centers, multi-axis CNC mills, or production turning centers, our clamping tools ensure secure tool retention, minimal runout, and consistent performance throughout extended production runs.
Our precision collet range delivers exceptional clamping accuracy for CNC milling, drilling, and boring operations. Available in ER series (ER8 through ER50), 5C, R8, and OZ configurations, each collet is manufactured from premium alloy steel with precision-ground clamping surfaces.
Key Features:
Whether you require standard ER collets for general machining or ultra-precision collets for finishing operations, TNT Motion provides solutions that maintain accuracy across thousands of tool changes.
Pull studs are critical components that secure toolholders in the machine spindle. Our retention knobs are precision-manufactured to ensure perfect fit, reliable clamping, and safe operation at high speeds.
Available Standards:
All pull studs undergo rigorous quality control including dimensional verification, thread inspection, and hardness testing to ensure reliable performance in demanding production environments.
Precision clamping nuts complete the collet chuck assembly, providing the clamping force needed to secure tools firmly in position. Our clamping nuts feature precision-ground threads, balanced construction, and optimized geometries for high-speed applications.
Product Highlights:
Properly matched clamping nuts ensure even pressure distribution around the collet, maximizing grip strength while preserving collet life and maintaining concentricity.
TNT Motion offers a comprehensive range of CNC toolholders designed for precision, rigidity, and reliability. Our toolholders accommodate various tool clamping methods including collet chucks, end mill holders, shrink fit, hydraulic, and mechanical grip systems.
Taper Options:
Holder Types:
Each toolholder is manufactured to precise tolerances, heat-treated for durability, and available with various gauge lengths to suit your specific machining requirements.
We offer a complete range of precision collets including ER collets (ER8 to ER50), 5C collets, R8 collets, and OZ collets. All our collets feature tight tolerances and excellent concentricity for precision machining.
TNT Motion supplies pull studs (retention knobs) for all major standards including BT30, BT40, BT50, CAT40, CAT50, ISO30, ISO40, ISO50, and HSK toolholders. Custom configurations are available upon request.
Toolholder selection depends on your spindle taper type (BT, CAT, HSK, ISO), required tool clamping method (collet, end mill, shrink fit), and application requirements. Our technical team can assist with selection.
Our standard precision collets achieve runout of 0.008mm or better at 4xD. High-precision versions are available with runout under 0.005mm for demanding applications requiring exceptional accuracy.
Yes, we offer dynamically balanced clamping nuts rated for spindle speeds up to 30,000 RPM. These feature precision-ground threads and optimized mass distribution for vibration-free high-speed operation.
Absolutely. We provide complete CNC tooling solutions including matched sets of toolholders, collets, clamping nuts, and pull studs. This ensures optimal compatibility and performance across your tooling system.
Our clamping tools serve aerospace, automotive, medical device manufacturing, mold & die, general precision machining, and production job shops requiring reliable, high-precision toolholding solutions.
