Seco 02444854 Threading Insert 48-16 Tpi 60 Degree Carbide

Product Description

The SECO 02444854 is a laydown threading insert designed for external partial-profile 60-degree thread cutting on CNC lathes and threading toolholders. Built from solid carbide in the CP500 grade and finished with a PVD-applied TiAlN/TiN coating, it handles a thread pitch range of 0.50 mm to 1.50 mm, covering 48 to 16 TPI in a single insert. The 9.53 mm inscribed circle and 3.47 mm thickness match the 16ER insert style. This insert is part of the Snap Tap series and is suited for machinists and toolroom technicians working with universal workpiece materials including steels, stainless, cast iron, and high-temp alloys.

The 02444854 is intended for right-hand external threading operations in production and job-shop environments. The partial-profile geometry covers a wide TPI range without requiring a dedicated insert for each pitch, making it a practical choice for shops threading multiple fastener standards. It is compliant with ISO insert standards and is compatible with 16ER-style toolholders used on manual lathes, CNC turning centers, and Swiss-type machines. Primary workpiece material codes K, M, P, and S indicate suitability across a broad range of common machined materials.

Key Features

• Solid carbide CP500 grade for consistent edge life across universal workpiece materials
• PVD TiAlN/TiN coating applied via physical vapor deposition for wear and heat resistance
• Covers 48-16 TPI (0.50 mm to 1.50 mm pitch) in a single partial-profile insert
• Right-hand, external threading orientation with 60-degree included angle
• 16ER insert style with 9.53 mm inscribed circle and A chipbreaker geometry
• ISO-standard insert dimensions for broad toolholder compatibility

Compatibility

Designed as a direct-fit replacement for 16ER-style laydown threading insert seats compliant with ISO standards. Compatible with toolholders accepting the 16ER insert style. Primary workpiece material codes K, M, P, and S indicate suitability for cast iron, stainless steel, carbon and alloy steel, and high-temperature alloys.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the spindle before seating or replacing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to achieve proper clamping torque without cracking the carbide substrate. Inspect the insert pocket for chips or debris before seating the new insert to ensure full, flat contact.
