Sandvik Coromant 5740408 Rckt Milling Insert Solid Carbide

Product Description

The SANDVIK COROMANT 5740408 is a round milling insert in the RCKT series, designed for use in milling cutters on CNC machining centers and milling machines. It is manufactured from solid carbide with a CVD-applied TiCN and TiN coating that improves wear resistance and extends tool life when cutting steel and stainless steel. The insert measures 0.5 inches in inscribed circle diameter and 0.1875 inches thick, with a 0.25-inch corner radius and a positive rake geometry. Eight cutting edges are available per insert, maximizing value per unit. It is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is suited for milling operations on steel and stainless steel workpieces, including both roughing and finishing passes where a rounded cutting edge geometry is required. The WM chip breaker is configured for these material groups and supports a maximum depth of cut of 0.0732 inches. Compatible cutter series include N331.32, R331.32, and RA200. It is classified under ANSI and ISO code RCKT 13 04 00-WM 235 and fits into the RCKT insert size 13 toolholder family. Typical applications include face milling, shoulder milling, and copy milling on CNC platforms.

Key Features

• Positive rake with WM chip breaker geometry optimized for steel and stainless steel material groups P and M
• Corner radius of 0.25 inches provides a robust rounded cutting edge suited to high-feed and copy milling operations
• Neutral hand orientation for flexible positioning in compatible cutter bodies
• Conforms to ANSI and ISO standards under code RCKT 13 04 00-WM 235

Compatibility

Compatible cutter series as stated by the manufacturer: N331.32, R331.32, and RA200. Insert size code 130400 fits RCKT 13 04 00 toolholder pockets. Designed for machining steel and stainless steel workpiece materials (ISO material groups P and M).

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and locked out before seating or indexing inserts. The insert is secured using the screw-holding method; use the correct Torx or hex key specified by the cutter body manufacturer and do not overtighten. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
