R8 ER Collet Chuck

 

R8 ER collet tool holder is designed with a locking keyway. When inserted into the spindle, the locking keyway is tightly coupled with a locking device. And then using a milling machine tie rod bolt pulls the cutter into the spindle, mounting and fastening.

The tool holder with integral nickel coating that makes the holder anti-rust, anti-corrosion, durability better. Through  -196℃ long Cryogenic Treatment and long time Thermal Aging Processing, the precision of tool holder and using life are higher and longer.

We are specializing in the production of R8 ER Spring Collet Chuck, we can to figure to sample processing, and perfect after-sales service and technical support. Looking forward to your cooperation!
