Schunk’s Tendo E Compact toolholder eliminates the need for different holder technologies for milling, drilling and reaming. This hydraulic expansion toolholder can safely transfer torques ranging to 520 Nm (384 foot-pounds) at a 20-mm clamping diameter and is well-suited for high-volume cutting. With good vibration damping and runout accuracy of less than 0.003 mm (0.0001") at 2.5×D, the Tendo E Compact protects the machine spindle and the cutting tool from damage. The hydraulic expansion toolholder is suitable for applications ranging from rough milling to finish operations such as reaming and fine milling, the company says.

Tools can quickly be changed with an allen key, making this hydraulic expansion toolholder an alternative for operations where the toolholder quantities do not justify peripheral equipment purchases. Common spindle connections are available, including HSK-A63, SK40, BT40, CAT40, and CAT50 interfaces.

  • Don’t Forget The Drawbar

    The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.

  • What to Consider When Adding Angle Heads

    Angle heads can enable a three-axis machine tool to be more versatile. That said, this shop explains that there’s more to getting started using them than simply loading them into a machine’s spindle.

  • The Real Cost Of Runout

    A seemingly small amount of runout can still be too large for the tool. Reduce this runout, and tool life or productivity may dramatically increase.
