Function: 1 Strong Abrasion Resistance: Made of 20CrMnTi steel material, hardened and hardened to have high surface hardness and strong wear resistance.
2. High concentration: The inside and outside of the tool holder are formed together. Fine-tuning process provides more stable performance and high concentration
3. Inner hole grinding processing: After the inner hole grinding process, it is suitable for high precision machine tools and has a longer lifespan than normal tool holders.
4.Stronger Fatigue Resistance:Using the carbon seizing and tempering process, the hardness is higher and the fatigue resistance of the interface is stronger and more durable.
5. 1-7mm clamp range: With a 1-7mm clamp range, the accuracy is less than 0.005mm, very reliable. 1000 rpm speed for high speed operation
