Product Description

BT 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. BT GER chuck has more stable characteristics can be gotten in high speed cutting process, improved service life. The BT GER tool holders are more suitable for higher speed and higher precision cutting.

Features:

1. Material: 20CrMnTi or JIS-SCM415

2. Hardness: 56-60HRC;

3 Taper precision ≤AT3 and part of the standard size are tested by Diebold standard inspection tools which made in Germany;

4 Run out of the inside shank cone: ≤0.002mm；Coaxiality with collet : ≤ 0.005mm；

5 Dynamic balance： G2.5 250000rpm;

6. Suitable for boring, milling, drilling, tapping, grinding, carving processing.

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 repeat 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.
