MT3 SLN High Precision End Mill Holder, apply to the holder of a DIN1835-B with a solid surface of the cutting tool,

high speed and high precision machining .Mechanical spindle and cutting tools and other accessories.

High Precision MT3 shank Tool Holder .Morse Taper End Mill Holders
R8 Tool Holders for mechanical spindle and cutting tool and other accessory tool connection. 

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.
