With the TENDO E compact toolholder from Schunk, milling, drilling and reaming no longer require different holder technologies. Hydraulic expansion toolholders can safely transfer torques of up to 520 Nm (384 foot-pounds) at a 20-mm clamping diameter and are perfectly suited for high volume cutting. With excellent vibration damping and precise runout accuracy of less than 0.003 mm (0.0001”) at 2.5 × D, this holder protects the machine spindle and the cutting tool from damage. The hydraulic expansion toolholder works well across the application range from rough milling to finish operations such as reaming and fine milling.

When compared with side lock holders used in roughing operations, tool cost reductions of up to as much as 40 percent have been achieved with the toolholder, the company says. Tools can be quickly changed with an Allen key, making this hydraulic expansion toolholder an excellent alternative for operations where the toolholder quantities do not justify peripheral equipment purchases, the company says.
