Seco 00077785 Threading Insert 2.00mm Pitch Iso

Product Description

The SECO 00077785 is a laydown threading insert designed for external ISO threading operations on CNC lathes and turning centers. Built from micrograin solid carbide with a CP500 manufacturer grade, this insert carries a PVD-applied TiAlN/TiN coating for extended tool life in demanding cutting environments. It features a 2.00mm pitch, a 60-degree included angle, and a right-hand cutting orientation. The A2 chipbreaker geometry promotes chip control during threading passes. At 0.1366 inches thick with a 3/8-inch inscribed circle, this insert seats into compatible Snap Tap series toolholders. Machinists and CNC operators working in job shops or production environments install this insert for precision thread-form generation.

This insert is optimized for threading stainless steel and other ISO material group M workpieces, where edge toughness and coating adhesion are critical. The PVD coating process preserves sharp cutting edges better than CVD alternatives, making it well suited for the work-hardening tendencies of austenitic and duplex stainless grades. It is intended for external thread profiles conforming to ISO standards at a 2.00mm pitch. Typical applications include threading hydraulic fittings, fasteners, and precision shafts on CNC turning equipment. The insert ships individually with a minimum order quantity of 2 units.

Key Features

• Micrograin solid carbide substrate in CP500 grade for toughness and wear resistance
• PVD TiAlN/TiN coating for sharp edge retention on stainless steel and ISO-M materials
• 2.00mm ISO pitch with 60-degree included angle for standard external thread profiles
• A2 chipbreaker geometry for controlled chip evacuation during threading passes
• Right-hand external cutting orientation in Snap Tap series format
• 3/8-inch inscribed circle and 0.1366-inch thickness for precise toolholder seating

Compatibility

Designed as an OEM-style replacement or direct application insert for Snap Tap series toolholders accepting a 16ER style laydown threading insert with a 3/8-inch inscribed circle.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before changing inserts. Use the appropriate torx or hex key to the toolholder manufacturer's recommended seating procedure — do not overtighten the clamping screw, as micrograin carbide inserts are brittle under uneven clamping loads. Verify insert orientation and chipbreaker direction against the toolholder specification before resuming cutting operations.
