Seco 00064786 Threading Insert 60 Deg 48-8 Tpi Solid Carbide

Product Description

The SECO 00064786 is a laydown threading insert designed for internal thread cutting operations on CNC lathes and turning centers. Built from micrograin solid carbide in the CP500 manufacturer grade, it features a PVD-applied TiAlN/TiN coating for extended tool life across a wide range of workpiece materials. The insert profiles 60-degree included angle threads at a thread pitch range spanning 48 to 8 TPI (0.50 to 3.00 mm pitch), making it suited for partial-profile internal threading passes. The 3/8-inch inscribed circle and 0.1366-inch thickness conform to standard laydown insert geometry for quick changeovers in compatible toolholders.

This insert is intended for use in metalworking and machining environments where internal threads must be cut with repeatable accuracy. The universal primary workpiece material classification covers ferrous metals, stainless steels, cast irons, and high-temperature alloys, giving it broad application across job-shop and production turning. The Snap Tap series designation and A1 chipbreaker geometry make it particularly well-suited for CNC turning centers running finish and semi-finish internal threading passes. Machinists and CNC operators in general machining, aerospace component work, and precision manufacturing will find this insert a consistent performer across material grades.

Key Features

• Solid micrograin carbide construction in CP500 grade for wear resistance and edge integrity
• PVD TiAlN/TiN coating extends tool life in universal workpiece materials including ferrous, stainless, and high-temp alloys
• 60-degree partial profile internal thread form covers 48 to 8 TPI (0.50 to 3.00 mm pitch)
• Right-hand cut geometry with A1 chipbreaker for controlled chip evacuation in internal bores
• ISO-standard insert geometry with 3/8-inch inscribed circle for compatibility with standard laydown toolholders
• Minimum order quantity of 2 per transaction; sold individually per package

Compatibility

Designed as an OEM-style replacement or direct-use insert for standard laydown internal threading toolholders accepting a 16NR insert style with a 3/8-inch inscribed circle. Conforms to ISO threading insert standards.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician with the machine in a fully stopped and locked-out state before insert indexing or replacement. Seat the insert firmly in the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification — do not overtighten micrograin carbide inserts as they are brittle under bending loads. Confirm thread pitch and feed rate settings in the CNC program match the insert's TPI range before initiating a threading cycle. Inspect the cutting edge and corner radius condition regularly, as insert wear on threading profiles can directly affect thread form accuracy and part acceptance.
