Seco 00018388 Turning Insert CP500 Solid Carbide Mdt

Product Description

The SECO 00018388 is a solid carbide multi-directional turning insert in the MDT series, designed for precision turning operations across a wide range of workpiece materials. Manufactured to the LCMF insert style with a neutral hand orientation, it carries a PVD-applied TiAlN/TiN coating over a micrograin solid carbide substrate in the CP500 grade. The cutting geometry features a 0.187 inch maximum cutting width, 0.177 inch cutting height, and a 0.5 mm corner radius, making it well-suited for controlled material removal in applications where directional flexibility is required. Licensed machinists and CNC turning specialists are the primary installers of this insert type.

This insert is applicable to turning centers and lathes handling a broad spectrum of workpiece material categories, including hardened materials (H), cast iron (K), stainless steel (M), non-ferrous materials (N), steel (P), and heat-resistant superalloys (S). The MDT series designation indicates compatibility with multi-directional turning toolholders that use a clamp-style insert holding method. It is suited for both roughing and finishing passes where a rectangular insert profile and 90-degree included angle deliver stable engagement and repeatable results.

Key Features

• CP500 micrograin solid carbide grade with PVD TiAlN/TiN coating for extended tool life across multiple material classes
• LCMF insert style, 160505 size code, with a neutral hand for flexible tool path direction
• 0.187 inch maximum cutting width and 0.177 inch cutting height for precise depth control
• 0.5 mm corner radius (0.0197 inches) reduces stress concentration at the cutting edge
• MT chipbreaker geometry supports controlled chip formation during turning operations
• 7-degree relief angle and 90-degree included angle provide stable clearance and edge support

Compatibility

Designed for use with MDT series multi-directional turning toolholders that accept LCMF-style inserts secured via clamp-style holding. Compatible with workpiece material groups H, K, M, N, P, and S as defined by the ISO material classification system.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder specification without overtightening. Inspect the insert seat and chipbreaker pocket for debris before seating the insert to ensure proper contact and repeatable tool height.
