Seco 00071679 Turning Insert LCGN1605020500FG CP500

Product Description

The SECO 00071679 is a solid carbide multi-directional turning insert in the MDT series, designed for precision grooving and turning operations on CNC lathes and turning centers. Carrying the LCGN1605020500FG designation with a manufacturer grade of CP500, this insert features a PVD coating applied over a micrograin solid carbide substrate. The cutting height measures 0.177 inches, the maximum cutting width reaches 0.197 inches (5.00 mm), and the insert length is 0.674 inches (17.10 mm). A neutral hand orientation and FG chipbreaker geometry make it suitable for a wide range of workpiece materials and chip control requirements.

This insert is engineered for single-end use in multi-directional turning and grooving applications across both light and medium-duty production environments. Its 7-degree relief angle and 0.008-inch corner radius suit finishing and semi-finishing passes on compatible MDT toolholders. Licensed machinists and CNC lathe operators working in job shops, aerospace component manufacturing, or general precision machining will find this insert appropriate for applications involving materials coded H, K, M, N, P, and S — covering hardened steels, cast irons, stainless steels, non-ferrous materials, carbon steels, and heat-resistant superalloys.

Key Features

• Solid carbide micrograin substrate with CP500 manufacturer grade for wear resistance in demanding cuts
• PVD coating process delivers a hard, low-friction surface for extended tool life
• FG chipbreaker geometry promotes effective chip control across varied feed rates
• Neutral hand (LCGN style) allows flexible mounting in MDT series toolholders
• 7-degree relief angle supports clean, low-force cutting on both ID and OD turning operations
• Compatible with primary workpiece material codes H, K, M, N, P, and S

Compatibility

Designed for use with MDT series multi-directional turning toolholders. Suitable for workpiece material codes H, K, M, N, P, and S as specified by the manufacturer. Verify toolholder pocket specifications before installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the insert. Ensure the toolholder pocket is clean and free of chips or debris before securing the insert. Follow the toolholder manufacturer's torque recommendations for the clamping screw to avoid insert cracking or improper seating.
