External Thread Turning Insert – 55° Partial Profile
The 55° Partial Profile External Thread Turning Insert is designed for machining a variety of British thread standards including BSW, BSF, BSP, and BSB. With a pitch range of 3.5 to 5.0 mm (7–5 TPI), this insert offers flexibility for coarse-pitch threading tasks while maintaining accuracy and form consistency.
Manufactured from high-performance P25C-grade carbide, the insert provides excellent wear resistance, edge stability, and thermal performance. Its partial profile design allows threading of multiple pitches with one tool, reducing tooling requirements. The X and Y geometry (1.7 mm and 2.5 mm) ensures efficient chip flow and smooth cutting in external right-hand applications.
