Seco 00016806 Turning Insert CP500 Solid Carbide Mdt

Product Description

The SECO 00016806 is a solid carbide multi-directional turning insert engineered for precision external turning and grooving operations on CNC lathes. Built to the LCMR160404-0400-MT style designation within the MDT (Multi-Directional Turning) series, it features a CP500 micrograin carbide grade with a PVD-applied TiAlN/TiN coating for improved wear resistance and edge integrity at elevated cutting temperatures. The insert has a 0.157-inch maximum cutting width, a 0.177-inch cutting height, a 0.630-inch insert length, and a 0.016-inch corner radius. Its neutral hand orientation allows flexible setup in both left- and right-hand toolholders. This insert is sold individually with a minimum order quantity of 10 units.

The 00016806 is designed for use in general-purpose and finish turning applications across a broad range of workpiece materials. The CP500 grade with MT chipbreaker geometry is suited for use on steel, stainless steel, cast iron, nonferrous metals, heat-resistant superalloys, and high-temperature alloys, corresponding to ISO material groups P, M, K, N, H, and S. It is typically installed by CNC machinists and toolroom technicians in production turning and profiling applications where controlled chip formation and consistent surface finish are required.

Key Features

• CP500 micrograin solid carbide grade with PVD TiAlN/TiN coating for extended tool life
• MDT series LCMR insert style with MT chipbreaker for controlled chip evacuation
• 0.157-inch maximum cutting width and 0.016-inch corner radius for precise groove and profile geometry
• Neutral hand design compatible with both left- and right-hand toolholding systems
• 7-degree relief angle reduces rubbing and supports clean entry on finish passes
• Rated for ISO material groups P, M, K, N, H, and S covering a wide range of workpiece materials

Compatibility

Designed as a direct-fit replacement insert for MDT-series toolholders using the LCMR160404 insert seat geometry. Specific compatible toolholder model numbers were not provided in the product data; verify seat geometry and clamping style against your toolholder documentation before ordering.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians following standard indexable insert replacement procedures. Power down and lock out the machine before accessing the turret or toolholder. Seat the insert fully against the pocket locating surfaces and torque the clamping screw to the toolholder manufacturer's specified value using a calibrated torque driver. Inspect the cutting edge and chipbreaker geometry under magnification before returning the machine to service.
