1. TIR: ≤0.0002″
2. Material: 20CrMnTi
3. Works on all MT3 Machines
4. Rear thread for pull stud is 1/2″-13 UNC
5. Constructed of alloy steel hardened to 56 – 60 HRC for long, durable service life
6.Nickel coating surface, Anti-rust, anti-corrosion, durability better.

Anti-rust, Anti-corrosion, Durability better◆ Coating adhesion strong, enhance hardness, and anti-rust better in different surroundings, such as acid, alkali, ammonia, salt etc.◆ Overall nickel coating, including inside and outside cone, even if you do not take any anti-rust actions, it will not rust either,don’t influence processing precision and spindle.◆ Improve cleanness, precision more stable, surface more smooth, feel more comfortable and appearance nicer.Cryogenic treatment◆ -384.8℉ long cryogenic, nearly all of the residual austenite into martensite.◆ Carbide precipitation of nanoscale particles, increasing the hardness and toughness.◆ Reducing residual stresses.◆ Wear resistance significantly improved.Thermal aging processing◆ long stereotyped thermal limitation removal of grinding residual stress.
