Seco 03245467 Threading Insert TTP2050 Solid Carbide 3/8 Ic

Product Description

The SECO 03245467 is a solid carbide laydown threading insert in the Snap Tap series, designed for external 60-degree V-thread cutting on CNC lathes and turning centers. Manufactured to the 16ER insert style, this insert carries a TTP2050 grade designation using micrograin carbide substrate and a PVD-applied TiAlN/TiSiN dual-layer coating for wear resistance and thermal stability at elevated cutting speeds. It features a 3/8-inch inscribed circle, a thickness of 0.1366 inches, and a right-hand cutting orientation. The chipbreaker designation is A. This insert is intended for use by machinists and toolroom operators running external threading operations across a broad range of workpiece materials.

The 03245467 is rated for universal primary workpiece material compatibility, covering ISO material groups K, M, P, and S — meaning it handles cast iron, stainless steels, carbon and alloy steels, and heat-resistant superalloys within a single insert grade. It covers a pitch range of 0.50 mm to 3.00 mm, equivalent to approximately 8 to 48 threads per inch, making it suitable for both fine and coarse thread forms on external diameters. Typical applications include threading in production turning, repair threading, and general-purpose external thread generation on a lathe or threading center.

Key Features

• Solid micrograin carbide substrate with PVD TiAlN/TiSiN coating for heat and wear resistance
• 60-degree included angle for standard V-thread profile, right-hand orientation
• Covers 8 to 48 TPI (0.50 to 3.00 mm pitch) in a single insert
• ISO-compliant geometry rated for universal material groups K, M, P, and S
• 3 teeth per side with A-style chipbreaker for controlled chip evacuation
• Corner radius of 0.0030 inches for defined thread root geometry

Compatibility

Designed as a direct-fit replacement for 16ER-style Snap Tap laydown threading insert holders accepting a 3/8-inch inscribed circle insert with a 4.00 mm mounting hole diameter, conforming to ISO threading insert standards.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and the toolholder secured in the turret before seating or removing the insert. Torque the clamping screw to the toolholder manufacturer specification only — do not over-torque. Verify insert seating and orientation visually before initiating a threading pass, and confirm thread pitch and hand against the workpiece drawing before cutting.
