Applications

This full-profile threading insert is designed for the production of media-tight, conical internal threads in pipeline construction, hydraulics, and pneumatics. Thanks to its universal suitability for steel, stainless steel, non-ferrous metals, and special materials, the tool reduces setup times and simplifies inventory management.

Due to the adaptable cutting edge geometry, the indexable insert masterfully handles varying material strengths. This creates favorable conditions for the series production of fittings, valve housings, and industrial connection elements.

Special features

During thread turning, the BSPT full profile machines the thread root and crest in addition to the flanks, resulting in a standard-compliant profile shape in a continuous process. In many cases, this eliminates the need for time-consuming reworking and ensures accurately fitting, functionally reliable screw connections.

Furthermore, the PVD-coated RT315 grade convinces with a well-balanced combination of toughness and thermal stability. These properties counteract premature edge wear and support a consistent machining process even at varying cutting speeds.
