Professional Turning Insert for Soft Materials
The uncoated WNMG ... -ALP RT100 indexable insert is strictly designed for the turning operations of aluminum, plastics, and non-ferrous metals. Rinaldi-Tools combines a highly sharp cutting edge with the proven K10-K15 carbide grade for this tool. This specific setup ensures a smooth chip flow and effectively prevents annoying material build-up on the cutting edge. As a result, this turning insert is an excellent choice for users who rely on reproducible dimensional accuracy and superior surface finishes during continuous or slightly interrupted cuts.

Applications
Thanks to its specialized material combination, the WNMG ... -ALP RT100 finds its ideal field of application in both series and single-part production of aluminum components and high-strength plastics. It supports turning processes where smooth contours without chatter marks are required. The robust basic shape of the insert also opens up flexible application possibilities in slightly interrupted cutting conditions, which frequently occur with cast housings or pre-machined profiles.
Special features
The decisive advantage of this turning insert lies in the ALP geometry, which noticeably reduces the cutting pressure due to its highly sharp design. This protects the machine components and minimizes heat generation at the cutting edge. Because the RT100 grade is completely uncoated, the edges remain exceptionally sharp – an essential feature for achieving excellent results when working with soft and smearing materials such as pure aluminum.
