Seco 00077941 Threading Insert CP500 Carbide 48-8 Tpi

Product Description

The SECO 00077941 is a solid carbide laydown threading insert designed for external thread cutting operations. Part of the Snap-Tap series, it carries a CP500 manufacturer grade and features a TiAlN/TiN PVD coating for extended tool life across a range of workpiece materials. The insert covers a thread pitch range of 48 to 8 TPI (0.50 to 3.00 mm pitch) using a partial profile 60-degree thread form. With a 3/8-inch inscribed circle and a thickness of 0.1366 inches, it is sized for standard laydown-style toolholders. This insert is installed by machinists and CNC operators performing precision threading on lathes and turning centers.

This insert is suited for right-hand external threading on a broad range of materials, including steel, stainless steel, cast iron, and high-temperature alloys, as indicated by the universal workpiece material designation covering material codes K, M, P, and S. The partial profile 60-degree thread standard makes it appropriate for general-purpose unified and metric thread forms where a full-profile insert is not required. Typical applications include production threading on turning centers in both job shop and manufacturing environments where one insert must cover multiple thread pitches.

Key Features

• Solid carbide construction with CP500 grade for wear resistance and edge stability
• TiAlN/TiN PVD coating provides heat resistance and extended tool life
• Covers 48 to 8 TPI (0.50 to 3.00 mm pitch) for broad threading range in one insert
• Right-hand external partial profile 60-degree thread form suits unified and metric applications
• 16ER insert style with A2 chipbreaker geometry in the Snap-Tap series

Compatibility

Designed for use in 16ER-style Snap-Tap laydown threading toolholders. Verify toolholder seat geometry and clamping method before installation. No specific machine or toolholder model numbers were provided in the product data.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the toolholder pocket and seating surface are clean and free of chips before clamping. Follow the toolholder manufacturer's recommended clamping torque and do not exceed insert overhang beyond toolholder specifications.
