Sandvik Coromant 5744702 Round Milling Insert Carbide 0.5 in

Product Description

The SANDVIK COROMANT 5744702 is a round, solid carbide milling insert in the R300 series, designed for high-performance face and shoulder milling operations. Manufactured to ANSI and ISO standards with catalog designation R300-1340M-MM 2030, this insert features a TiAlN and TiN PVD coating applied over a Grade 2030 solid carbide substrate. The round insert shape provides six usable cutting edges per insert, maximizing value per tool change. With a 0.5-inch inscribed circle, a 0.156-inch thickness, and a 0.25-inch corner radius, it suits medium to heavy metal removal in demanding applications. The positive rake geometry and MM chip breaker promote free cutting action and effective chip control.

This insert is engineered for machining steel, stainless steel, superalloys, and titanium, corresponding to material grades P30, M25, and S20. It is compatible with the RA300 cutter series and is held in place by a screw-clamping method. Typical applications include face milling and ramping operations in aerospace, general metalworking, and energy-sector part production. The neutral hand designation makes it suitable for use in both left- and right-hand tool configurations. Maximum depth of cut reaches 0.125 inches (3.18 mm), which positions this insert well for finishing and semi-finishing passes on difficult-to-machine materials.

Key Features

• Round insert shape with 6 cutting edges for extended tool life per insert
• TiAlN and TiN PVD coating for high heat resistance and wear performance on hard materials
• Grade 2030 solid carbide substrate rated for steel (P30), stainless steel (M25), and superalloys and titanium (S20)
• Positive rake angle of 20 degrees reduces cutting forces and improves chip flow
• MM chip breaker geometry optimized for medium machining conditions
• Screw-held, single-sided insert with neutral hand for flexible cutter compatibility

Compatibility

Designed for use with the RA300 cutter series. ANSI and ISO code: R300-1340M-MM 2030. Insert size code 1340. Suitable for cutters requiring a 0.5-inch inscribed circle round insert with screw clamping.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer to secure the clamping screw. Inspect the cutter pocket and screw threads for wear or debris before seating the insert to ensure proper seating and runout.
