Notes 

  • Please check the style and size before purchasing.
  • Please note that the collet must be assembled into the clamping nut(not included) before inserting it into the chuck.
  • Please measure the collet deviation before using the collet. If the collet deviation accuracy exceeds 0.0004 inches, please correct it before cutting.
  • The collet extension time is longer when the collet shortens the chuck length as much as possible. If it is extended, please reduce the speed, feed rate, or cutting volume by yourself.
  • If abnormal vibration or sound occurs during cutting, please reduce the spindle speed and depth of cut.
