Seco 00071661 Turning Insert CP500 Solid Carbide Tialn/tin

Product Description

The SECO 00071661 is a solid carbide multi-directional turning insert designed for precision turning operations on CNC and manual lathes. Manufactured in the CP500 grade using micrograin solid carbide, this insert carries a PVD-applied TiAlN/TiN coating that improves wear resistance and thermal stability during cutting. It features a neutral hand orientation, an FG chipbreaker, and a 7-degree relief angle. Key cutting geometry includes a 0.104-inch maximum cutting width, a 0.177-inch cutting height, and a 0.008-inch corner radius. This insert is part of the MDT series, which is engineered for multi-directional toolpaths in grooving and turning applications.

This insert is suited for metalworking applications where multi-directional cutting paths are required, including axial and radial turning and grooving on CNC machining centers and turning centers. The FG chipbreaker geometry is optimized for fine-grain chip control in moderate to light cutting conditions. It is a single-end, non-full-radius insert with an LCGN-style seating configuration and a standard lock ring size of 0.099 inches. Machinists and tool-crib personnel in manufacturing and job-shop environments will specify this insert for applications demanding consistent geometry and coating performance across diverse workpiece materials.

Key Features

• CP500 micrograin solid carbide substrate for elevated hardness and edge retention
• PVD TiAlN/TiN coating for improved thermal resistance and wear life
• FG chipbreaker geometry designed for fine-grain chip control
• Neutral hand orientation for flexible toolholder compatibility
• 7-degree relief angle suits light-to-moderate turning and grooving passes
• LCGN style and MDT series designation for straightforward toolholder matching

Compatibility

Designed as an OEM-style replacement or direct-fit insert for MDT-series toolholders accepting LCGN-style inserts with a 0.099-inch standard lock ring size.

Installation Notes

This insert is installed and changed by machinists or toolroom technicians following standard CNC safe-work procedures. Always power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torque wrench and locking screw to secure the insert without over-torquing the seat. Verify insert orientation and chipbreaker direction against the toolholder specification sheet before resuming operation.
