What is a Wiper insert?

Our wiper inserts have a trailing edge at the radius outlet.

Advantages of using wiper geometry:

  • Improvement of the surface finish
    With the same feed rate, you achieve 2-4 times better surface quality with our wiper geometry.
  • Reduction of the cycle time
    With the same surface quality, the feed rate can be increased by 2-4 times, thus reducing the machining time.
