- 1. Structural Design
 Standardized interface: The tail adopts R8 taper, which is suitable for traditional vertical milling machine spindles, with strong compatibility and suitable for upgrading old equipment.
 Clamping flexibility:
 The front end can be optionally equipped with ER spring chuck, which is suitable for a wide range of tool diameters (such as φ3~φ25mm).
 Some models support quick-change chuck system to shorten tool change time and improve processing efficiency.
 Material and process:
 The tool handle body is made of 42Cr, which is tempered and hardened to enhance wear resistance and vibration resistance.
- 2. Performance advantages
 High-precision clamping:
 The ER spring chuck system can achieve radial runout ≤0.01mm, meeting the needs of semi-finishing to finishing (such as mold corner cleaning and thin-walled parts processing).
 The side-fixed design provides higher rigidity and is suitable for heavy cutting scenarios (such as steel roughing).
 Optimized rigidity: The short handle design reduces the overhang and the self-locking effect of the cone surface improves the anti-vibration ability, which is suitable for intermittent cutting or deep cavity processing.
