Applications
This turning insert was developed specifically for machining softer, smeary non-ferrous metals and technical plastics. It demonstrates its strengths in turning operations involving continuous cuts and handles light interruptions with equal confidence. This makes it a versatile tool for general mechanical engineering and the production of precision aluminum components.
Special features
Thanks to the uncoated K10-K15 carbide, the cutting edge is characterized by exceptional sharpness, reducing cutting forces and ensuring excellent surface quality. With a choice of two corner radii (0.4 mm and 0.8 mm), the tool can be flexibly adapted to specific surface finish requirements and part contours. A practical packaging unit of 10 pieces provides professionals with a highly economical solution for regular turning tasks.
