High Quality ISO GER Tool Holders, apply to high speed and high precision machining .High Precision ISO shank tool holder can achieve G2.5 30000 RPM. ISO GER chucks are special used for small CNC machining center, wooden, engraving and milling machine, plane copying milling machine with scaling instrument, and suitable for drilling, milling, wooden, engraving, high precision, widely used in precision processing.  Main models include ISO10, ISO20, ISO25 and ISO30.

ISO GER collet chuck usually using with ER collet. GER Tool holder series has less protrusion length and more contact area than normal ER tool holder, so can provide higher radial cutting force, and greatly increase the clamping power. GER chuck has more stable characteristics can be gotten in high speed cutting process, improved service life. The GER tool holders are more suitable for higher speed and higher precision cutting.

Our advantages

1. Good Rigidity

2. High accuracy stability of parts processing and surface processing dimension

3. Improving cutting tool using life

4. The wear of taper shank caused by vibration is reduced during heavy cutting

5. ATC repeats the operation with high accuracy

6. The appearace with nickel coating, the products are anti-rust, anti-corrosion and durability better.

4. Clean appearance and accuracy stable

5. -196℃ long cryogenic treatment and ultra long time thermal aging processing, reducing residual stresses and increasing the hardness and toughness.
