Applications
This full profile threading insert demonstrates its strengths in professional mechanical engineering and series production. Since it completely forms the thread in one operation, it is ideally suited for precise connections where the dimensional accuracy of the outer diameter is strictly specified. The universal grade RT315 also opens up flexible application options in various steels and stainless materials.
Special features
The PVD-coated substrate of the RT315 grade combines a balanced toughness with high wear resistance, which creates favorable conditions for consistent workflows at cutting speeds of 60 to 90 m/min. In addition, the metric full profile ensures that burr formation is minimized and precisely fitting, visually flawless threads are produced.
