Seco 00091357 Turning Insert TCMT32.52-F1 CP500

Product Description

The SECO 00091357 is a TCMT-style triangular turning insert designed for precision metal cutting in CNC lathes and turning centers. Manufactured from solid carbide and finished with a multilayer PVD TiAlN and TiN coating under the CP500 grade designation, this insert delivers consistent cutting performance on demanding workpiece materials. The triangular shape provides three usable cutting edges, and the F1 chip breaker geometry produces a sharp edge with a positive rake angle suited for finishing and semi-finishing applications. The 3/8-inch inscribed circle and 1/32-inch corner radius define its size class within the TCMT series.

This insert is primarily applied to stainless steel machining, with secondary suitability for steel, cast iron, super-alloys, and titanium. It fits screw-on insert toolholders with TCMT-compatible pockets and is used in back turning, boring, facing, and general turning operations. The CP500 PVD coating and positive rake geometry make it well suited for interrupted cuts and heat-sensitive alloys where CVD-coated inserts may induce thermal cracking. Licensed machinists, CNC operators, and tool-and-die professionals are the primary installers in production and job-shop environments.

Key Features

• CP500 grade with multilayer PVD TiAlN and TiN coating for stainless steel and super-alloy applications
• F1 chip breaker with sharp, positive-rake cutting edge for clean finishes on difficult materials
• Three cutting edges per insert with neutral hand orientation for versatile toolholder use
• Screw-clamped seating method with TCMT pocket compatibility and 7-degree relief angle
• Suitable for back turning, boring, facing, and turning in a single insert geometry
• Meets ANSI and ISO standards; ISO code TCMT16T308-F1 for international toolholder cross-reference

Compatibility

Designed to seat in TCMT-compatible screw-on turning toolholders. ISO code TCMT16T308-F1 and industry standard number TCMT32.52-F1 apply for toolholder pocket cross-reference. Compatible with material grades M10, M20, and M30 per ISO classification. Primary workpiece material code M (stainless steel); secondary codes P (steel), K (cast iron), and S (super-alloys and titanium).

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before seating or removing inserts. Use the manufacturer-specified torque wrench for the clamping screw to ensure proper insert seating without fracturing the carbide body. Inspect the toolholder pocket for wear or debris before installing a new insert, and confirm the pocket geometry matches the TCMT clearance and tolerance codes.
