Seco 02960883 Turning Insert VBMT21.51-F1 TP2501 Carbide

Product Description

The SECO 02960883 is a solid carbide turning insert in the VBMT-F1 series, designed for precision metal cutting on CNC and manual lathes. It features a 35-degree diamond shape (V insert) with a 5-degree relief angle and a 1/64-inch corner radius. The CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — delivers wear resistance and thermal stability suited to interrupted and continuous cuts. With 2 cutting edges and a screw-holding method, this insert is a practical choice for high-volume turning operations targeting steel and stainless steel. Licensed machinists and CNC operators in production shops are the primary users.

The 02960883 is rated for back turning, facing, profiling, and general turning on steel (ISO material code P), stainless steel (M), and cast iron (K). It carries material grade designations P10, P20, P30, and P35, covering a broad range of steel hardness and feed conditions. The F1 chip breaker geometry produces a sharp cutting edge with positive rake, making it effective for light-to-medium depth cuts up to 0.4173 inches. The insert conforms to both ANSI and ISO standards, with the ISO designation VBMT110204-F1.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before indexing or replacing the insert. Seat the insert fully against the pocket locating surfaces before tightening the clamping screw to avoid micro-movement during cutting. Inspect the insert seat and screw threads for chips or debris before each installation.
