Seco 00049553 Threading Insert 0.75mm Iso External CP500

Product Description

The SECO 00049553 is a laydown threading insert engineered for external ISO thread cutting on CNC lathes and threading toolholders. Built from solid carbide in the CP500 grade, this insert features a PVD-applied TiAlN/TiN coating that reduces heat buildup and wear during high-speed threading passes. Sized at a 9.53mm inscribed circle with a 3.47mm thickness, the 00049553 carries a 60-degree included angle and a right-hand cutting orientation. It is suited for threading operations at a 0.75mm pitch across a broad range of workpiece materials, making it a versatile choice for production threading environments.

This insert belongs to the Snap Tap series and is designed for right-hand external ISO threading applications. The CP500 grade with PVD coating supports use on a universal range of workpiece materials including cast iron, steel, non-ferrous metals, high-temperature alloys, and stainless steel, as designated by material codes K, M, N, P, and S. It is appropriate for both light-production and job-shop threading on CNC turning centers where consistent thread form and tool life are priorities. Sold individually per package with a minimum order quantity of 2.

Key Features

• Solid carbide construction in CP500 grade for wear resistance and thermal stability
• PVD-applied TiAlN/TiN coating reduces friction and extends cutting life
• 0.75mm ISO pitch with a 60-degree included angle for standard ISO external threads
• 9.53mm inscribed circle (0.3752 inches) fits standard 16ER-style toolholders
• Right-hand cutting orientation for conventional external threading setups
• Universal material compatibility across K, M, N, P, and S workpiece material groups

Compatibility

Designed as an OEM-style replacement insert for 16ER-series laydown threading toolholders accepting a 9.53mm inscribed circle and 3.47mm insert thickness in right-hand external ISO threading configurations.

Installation Notes

Installation is performed by machinists or CNC operators during scheduled insert changeover on turning centers. Power down and lock out the spindle before accessing the toolholder. Seat the insert fully against the pocket and tighten the clamping screw to the toolholder manufacturer's specified torque using the appropriate Torx or hex key. Verify thread form and pitch with a thread gauge after the first pass before committing to a full production run.
