It carries a TiN (titanium nitride) coating applied via PVD process, which extends tool life across a broad range of workpiece materials. The insert runs at 19 threads per inch (TPI) with a 55-degree included angle, conforming to the B.S.21:1985 standard. The 3ER insert style seats in a standard laydown toolholder. Licensed machinists and CNC operators install this insert as a direct replacement or initial tooling setup for pipe thread turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external BSPT pipe thread production in both production shop and job shop environments. Its universal material grade (VKX) and multi-material workpiece compatibility codes (H, K, M, N, P, S) make it appropriate for threading carbon steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and plastics. It fits standard 3ER-series laydown threading toolholders and is commonly used wherever B.S.21:1985 pipe thread profiles are required on turned components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with PVD-applied TiN coating for extended wear resistance\u003c\/li\u003e\n\u003cli\u003e19 TPI external BSPT thread form, 55-degree included angle per B.S.21:1985\u003c\/li\u003e\n\u003cli\u003e3ER insert style, 3\/8 inch (9.53 mm) inscribed circle, 3.60 mm thickness\u003c\/li\u003e\n\u003cli\u003eVKX grade with universal workpiece material compatibility across six material groups\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for standard external threading direction\u003c\/li\u003e\n\u003cli\u003eSingle tooth per side design for precise thread profile control\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3ER-style laydown threading toolholders.
