Seco 00049679 Threading Insert 1.25mm Iso External CP500

Product Description

The SECO 00049679 is a laydown threading insert designed for external ISO threading operations on CNC lathes and turning centers. Built from solid carbide with a PVD-applied TiAlN/TiN coating under the CP500 grade designation, this insert delivers consistent thread form geometry on a wide range of workpiece materials. It cuts a right-hand external ISO thread at a 1.25mm pitch with a 60-degree included angle. The inscribed circle measures 9.53mm (0.3752 inches) and the insert thickness is 3.47mm (0.1366 inches). The CP500 grade is engineered for universal material compatibility, making it suitable across ferrous and non-ferrous applications. Licensed machinists, toolroom operators, and CNC programmers specify this insert in production threading setups.

The 00049679 belongs to the SECO Snap Tap series and is intended for external threading where precise ISO thread form and repeatable pitch accuracy are required. The 16ER insert style fits compatible Snap Tap toolholders designed for the 16-size insert. Applications include threading on turned components in general manufacturing, aerospace part production, and precision machining environments. The universal workpiece material classification covers cast iron, stainless steel, non-ferrous metals, steel, and superalloys, making this insert a versatile single-grade option across mixed-material production runs.

Compatibility

Designed for use with SECO Snap Tap series toolholders that accept the 16ER insert style. No additional specific compatible model numbers were provided in the product data.

Installation Notes

Insert seating and clamping should be performed with the machine fully stopped and spindle locked. Use the correct torx or clamp screw driver specified for the toolholder to achieve proper seating without over-torquing the clamping mechanism. Verify insert orientation and confirm right-hand thread direction matches the programmed toolpath before resuming cutting operations. This insert is sold individually per package with a minimum order quantity of 2 units.
