Seco 03096320 CNMG543-MR7 TP3501 Turning Insert Carbide

Product Description

The SECO 03096320 is a CNMG543-MR7 series indexable turning insert manufactured from solid carbide and finished with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr. It carries a TP3501 grade designation and is engineered for negative-rake, neutral-hand turning operations. The insert features an 80-degree diamond shape, a 5/8-inch inscribed circle, a 3/64-inch (0.0472 inch) corner radius, and 1/4-inch insert thickness. Four cutting edges are available per insert, and the T-Land cutting edge style improves edge strength under interrupted or heavy cuts. This insert is held using clamp, pin, or lever-lock toolholders.

This insert is suited for steel and stainless steel workpiece materials, covering ISO material groups P and M. Grade TP3501 with P20, P30, and P40 material grade ratings makes it appropriate for a broad range of general turning, facing, and boring applications in production machining environments. The MR7 chip breaker geometry is designed to manage chip flow across varying depths of cut up to 0.5866 inch. It conforms to ANSI and ISO standards and carries the ISO designation CNMG160612-MR7, making it a compatible drop-in replacement in any toolholder designed for that geometry.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for wear resistance and thermal stability
• TP3501 grade covers P20, P30, and P40 material grades for versatile steel and stainless steel cutting
• MR7 chip breaker geometry handles turning, facing, and boring with consistent chip control
• Four usable cutting edges per insert reduce per-edge tooling cost
• T-Land cutting edge style adds edge strength for heavier or interrupted cuts
• Negative rake, 80-degree diamond shape (CNMG) accepted by a wide range of standard toolholders

Compatibility

Designed for use in CNMG-style toolholders that accept clamp, pin, or lever-lock insert holding methods. ISO designation CNMG160612-MR7 and industry standard number CNMG543-MR7 apply. Compatible with ANSI- and ISO-standard CNMG-format toolholders. Multi-use applications include boring, facing, and turning.

Installation Notes

Installation is performed by machining professionals or CNC setup technicians using appropriate torx or hex insert-clamping hardware per toolholder manufacturer specifications. Always index or replace inserts with the machine fully stopped and spindle locked. Inspect the insert pocket and seating surface for chips or debris before seating a new insert, as contamination can cause insert rocking and premature edge failure. Follow the toolholder manufacturer torque guidelines for clamping screws — do not overtighten.
