Seco 03096316 CNMG542-MR7 TP3501 Carbide Turning Insert

Product Description

The SECO 03096316 is a CNMG542-MR7 indexable turning insert designed for medium to heavy-duty metal cutting operations. It features a solid carbide substrate with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, which improves wear resistance and thermal stability at the cutting zone. The insert has an 80-degree diamond shape, a neutral hand orientation, a 5/8-inch inscribed circle, and a 1/32-inch corner radius. With 4 cutting edges and a T-Land cutting edge style, it delivers consistent performance across roughing and semi-finishing passes. CNC machinists and turning center operators working on steel and stainless steel components will find this insert suited to production-volume work.

This insert is built for boring, facing, and turning applications on steel and stainless steel workpieces. It targets material grades P20, P30, and P40 for steel and M-grade stainless steel. The MR7 chip breaker geometry controls chip evacuation during continuous and interrupted cuts at moderate to aggressive feeds. It is compatible with CNMG-style insert pockets that accept clamp, pin, or lever lock holding methods, making it adaptable across a wide range of toolholders used on CNC lathes and boring bars in both job-shop and production environments.

Key Features

• CVD Duratomic TiCN, Al2O3, and Cr multilayer coating for elevated heat and wear resistance
• 80-degree diamond insert shape with negative rake and 0-degree relief angle for rigid, stable cutting
• MR7 chip breaker geometry designed for steel and stainless steel chip control at production feeds
• 4 indexable cutting edges per insert to maximize cost-per-edge value
• T-Land cutting edge style improves edge strength on interrupted cuts and hard materials
• Multi-use geometry supports boring, facing, and turning in a single insert grade

Compatibility

Designed for use in CNMG-style insert pockets accepting clamp, pin, or lever lock holding methods. Primary workpiece material is steel (P20, P30, P40); secondary workpiece material is stainless steel. ISO code CNMG160608-MR7 and industry standard number CNMG542-MR7 apply. Conforms to ANSI and ISO insert standards.

Installation Notes

Installation is performed by qualified machinists or tooling setup technicians on CNC or manual turning equipment. Always index or replace the insert with the machine powered off and the spindle fully stopped. Seat the insert flush in the pocket and verify the clamping method is secure before any test cut. Follow the toolholder manufacturer torque and clamping guidelines for the specific holding system in use.
