Sandvik Coromant 5742575 Milling Insert Grade 1020 Carbide

Product Description

The SANDVIK COROMANT 5742575 is a solid carbide milling insert designed for use in R210 series face and shoulder milling cutters. Coated with TiAlN via a PVD process, it carries manufacturer grade 1020 and material grade K05, making it well suited for machining cast iron. The insert measures 5.26 mm (0.2071 inches) thick with an inscribed circle of 14.60 mm (0.5748 inches) and a 1.40 mm (0.0551 inches) corner radius. It features a positive rake angle of 10 degrees, a KM chip breaker, and four usable cutting edges on a square, single-sided body. Machinists and toolroom professionals install this insert in compatible R210 cutter bodies.

This insert is intended for precision milling of cast iron workpieces in industrial machining environments. The KM chip breaker geometry promotes controlled chip formation at moderate to high feed rates. With a maximum depth of cut of 1.90 mm (0.0787 inches) and a neutral hand orientation, it fits standard R210 cutter body setups used in both roughing and finishing operations on ferrous materials. ANSI and ISO standards compliance is noted, with catalog designation R210-14 05 14E-KM 1020.

Key Features

• Solid carbide construction with PVD-applied TiAlN coating for wear resistance in cast iron applications
• Grade 1020 with K05 material grade classification optimized for cast iron
• Four cutting edges per insert maximizing tool life per unit
• KM chip breaker geometry for controlled chip evacuation
• Positive rake angle (10 degrees) reduces cutting forces on the workpiece
• Screw-held, single-sided square insert with 90-degree included angle for consistent seating

Compatibility

Designed for use with R210 series milling cutter bodies per ANSI and ISO designation R210-14 05 14E-KM 1020. Insert size code 140514 applies. Confirm cutter body pocket specifications match before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before removing or seating inserts. Use the appropriate Torx or hex key for the clamping screw and ensure the insert pocket and seating surface are clean and free of chips or debris before securing the insert. Follow the cutter body manufacturer torque guidelines for the clamping screw to avoid cracking the carbide substrate.
