Seco 00071649 Turning Insert LCGN1603000115FG CP500

Product Description

The SECO 00071649 is a solid carbide multi-directional turning insert designed for precision grooving and turning operations on CNC lathes and turning centers. Cataloged under the MDT series, this insert carries the LCGN1603000115FG style designation and is manufactured in the CP500 grade using a micrograin solid carbide substrate with a PVD coating process. The FG chipbreaker geometry supports controlled chip formation across a range of workpiece materials. With a maximum cutting width of 0.045 inches and a maximum depth of cut of 0.055 inches, this insert is suited for narrow, accurate groove profiles in production environments. Installation and tool changes are performed by qualified machinists or CNC tooling technicians.

This insert is used in single-end grooving and turning applications across multiple workpiece material categories, including hardened materials (H), cast iron (K), stainless steel (M), non-ferrous materials (N), steel (P), and superalloys (S). The neutral hand orientation allows flexible toolholder mounting. Typical applications include external and internal grooving, parting-adjacent operations, and profile turning where tight width tolerances are required. It is packaged individually but sold in a minimum order quantity of 10 units.

Compatibility

Designed as an OEM-style replacement or direct sourcing option for MDT-series toolholders accepting LCGN-style inserts with a standard lock ring size of 0.040 inches.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist with the machine powered down and the spindle locked. Verify that the toolholder pocket and lock ring are free of chips and debris before seating the insert. Use the correct torque wrench and manufacturer-specified clamping hardware to secure the insert without over-torquing. Inspect the insert edge condition before each production run and replace at first sign of chipping or dimensional drift.
