Seco 03096640 Turning Insert TCMT16T304-F1 TP3501 Carbide

Product Description

The SECO 03096640 is a solid carbide turning insert in the TCMT-F1 series, designed for precision metal cutting in CNC turning applications. It carries the ISO designation TCMT16T304-F1 with manufacturer grade TP3501 and a Duratomic CVD coating of TiCN, Al2O3, and Cr layers. The triangular insert shape provides three cutting edges, a 3/8-inch inscribed circle, a 1/64-inch corner radius, and a 60-degree included angle. The F1 chip breaker geometry produces a sharp cutting edge with a positive rake, making it well suited for finishing and light-to-medium material removal on steel and stainless steel workpieces.

This insert is rated for turning, facing, boring, and back turning operations. Its primary workpiece material is steel (ISO code P), with stainless steel as the secondary material (ISO code M), and material grades P20, P30, and P40 apply. The screw-held mounting method fits standard TCMT-style toolholders. The neutral hand orientation allows use in a range of toolholder configurations. Machinists and CNC operators in job shops, production machining environments, and maintenance facilities will find this insert practical for general-purpose turning and finishing passes.

Key Features

• Duratomic CVD coating (TiCN, Al2O3, Cr) for extended tool life on steel and stainless steel
• Three cutting edges per insert — triangular TCMT geometry with 60-degree included angle
• F1 chip breaker with sharp cutting edge and positive rake for clean chip formation
• Screw-held insert mounting for secure, repeatable seating in standard TCMT toolholders
• Multi-use application: back turning, boring, facing, and turning from a single insert
• Meets ANSI and ISO standards; ISO code TCMT16T304-F1, industry standard number TCMT32.51-F1

Compatibility

Designed for use in standard TCMT-style screw-clamp toolholders. Compatible with applications targeting steel (P20, P30, P40 material grades) and stainless steel workpieces. Verify toolholder pocket specifications match the TCMT insert seat geometry and screw hole diameter before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine before changing inserts. Use the correct torx or hex key to seat the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten, as this can crack the carbide insert. Inspect the insert pocket for chips or debris before seating the new insert, and confirm the cutting edge selected is free of damage before resuming operation.
