HT 800 WP - Application Tips

Please observe the following notes and recommendations for the application of Guhring‘s HT 800 WP tools:

We recommend when changing the insert to also replace the clamping screw!

Therefore, every holder is supplied with a clamping screw, Guhring no. 4071, and screwdriver, Guhring no. 1612. Every

interchangeable insert is also supplied with a clamping screw, Guhring no. 4071.

When changing the insert please observe the following tightening torques for the clamping screw. Adhering to them is

absolutely necessary for optimal machining results!
