Sandvik Coromant 5751099 SM30 Carbide Milling Insert

Product Description

The SANDVIK COROMANT 5751099 is a solid carbide, uncoated milling insert in the SPMT series, designed for indexable face and shoulder milling operations on steel and stainless steel workpieces. Carrying manufacturer grade SM30 and ANSI code SPMT432-WH SM30, this square-shaped insert features a positive rake angle, an 11-degree relief angle, and a WH chip breaker geometry. With four usable cutting edges and a corner radius of 0.0315 inches (0.80 mm), it delivers consistent chip control and edge integrity in demanding milling applications. Installation requires a screw-type insert holding method.

This insert is suited for production milling of steel (material code P) and stainless steel (material code M) in both industrial and job-shop environments. It is compatible with cutter bodies in the R215.64 and RA215.64 series. The bright, uncoated finish makes it well-suited for applications where coating adhesion to the workpiece is a concern or where sharp, free-cutting edge performance is required at moderate cutting parameters.

Key Features

• Solid carbide construction, uncoated (bright finish) for sharp, free-cutting performance
• SM30 grade with WH chip breaker geometry optimized for steel and stainless steel
• Square SPMT insert shape with 4 usable cutting edges, neutral hand
• Positive rake with 11-degree relief angle for reduced cutting forces
• Corner radius of 0.0315 inches (0.80 mm) for edge strength and surface finish
• Screw-on holding method for secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with Sandvik Coromant cutter series R215.64 and RA215.64. Conforms to ANSI standard SPMT432-WH SM30 and ISO standard SPMT 12 04 08-WH SM30. Designed for machining steel and stainless steel workpieces.

Installation Notes

This insert is installed and replaced by qualified machinists or toolroom technicians using the screw-on clamping method specified for the compatible cutter body. Before changing inserts, ensure the machine spindle is fully stopped and locked out per applicable machine safety procedures. Use the correct Torx or hex key for the clamping screw as specified by the cutter body manufacturer. Inspect the insert pocket and seating surface for chips or damage before seating a new insert.
