Catalog number: F12Q-STFPR 09-R Features: ● Carbide reinforced boring bar for deep hole boring with built-in vibration isolator for absorbing cutting vibration caused by tool. ● The dynamic rigidity of the vibration-proof bar is greatly increased by the vibration damping ability of the vibration isolator inside the bar. ● The protrusion length limit of normal steel boring bars is 4 times the tool diameter, but the protrusion length can be increased to about 10 times. Applications: ● For internal turning with longer protrusions. ● For suppressing vibration.
