Seco 02444864 Laydown Threading Insert 16NR CP500 Carbide

Product Description

The SECO 02444864 is a solid carbide laydown threading insert designed for internal partial-profile 60-degree thread cutting. Part of the Snap Tap series, it carries a CP500 grade designation and a TiAlN/TiN PVD coating applied via physical vapor deposition. The insert handles a thread pitch range of 0.50 to 3.00 mm, covering 48 to 8 TPI, making it a versatile choice for threading operations across a broad range of thread sizes. The 16NR insert style is a right-hand configuration, suited for internal threading applications in production and job-shop environments.

This insert is appropriate for use on CNC turning centers and lathes performing internal threading passes on a wide range of workpiece materials, including steels, stainless alloys, cast irons, aluminum, and superalloys, as reflected by its universal primary workpiece material classification with ISO material codes K, M, P, and S. It is a common choice for machinists and toolroom operators working to ISO thread standards who need a single insert geometry to cover multiple pitch sizes without a toolholder change.

Key Features

• Solid carbide substrate with CP500 manufacturer grade for wear resistance across universal workpiece materials
• TiAlN/TiN PVD coating for extended tool life and reduced built-up edge
• Partial-profile 60-degree internal thread form covering 48-8 TPI (0.50 to 3.00 mm pitch)
• Right-hand cut, 16NR insert style for standard internal threading toolholders
• Meets ISO standards for insert geometry and dimensional consistency
• Inscribed circle of 9.53 mm (0.3752 inches) for precise seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit insert for 16NR-style internal threading toolholders conforming to ISO insert standards. Compatible with toolholders accepting a 16NR laydown insert style with a 9.53 mm inscribed circle.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down the machine and engage all lockout/tagout procedures before seating or replacing inserts. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to secure the insert — do not overtighten by feel alone, as insert breakage can result. Inspect the insert pocket for chips or debris before seating to ensure full contact and accurate positioning.
