Sandvik Coromant 5853544 Milling Insert S40T Square

Product Description

The SANDVIK COROMANT 5853544 is a solid carbide milling insert in the R210 series, designed for use in positive-rake face milling and shoulder milling operations. It carries grade S40T with a CVD-applied multilayer coating of TiCrN, Al2O3, and TiN, delivering wear resistance and thermal stability when cutting difficult materials. The insert features a square shape with a 90-degree included angle, a corner radius of 1.40 mm (0.0551 inches), and a thickness of 5.26 mm (0.2071 inches). The PM chip breaker geometry supports controlled chip evacuation at moderate to aggressive feed rates. Screw-held and neutral-hand, this insert fits standard R210 cutter bodies.

This insert is engineered for machining stainless steel, superalloys, and titanium — ISO material groups M and S. It is suited for both roughing and semi-finishing passes where heat generation and edge wear are primary concerns. The maximum depth of cut is 1.90 mm (0.0787 inches). Typical applications include milling of aerospace components, process industry fittings, and medical parts where workpiece material toughness places high thermal and mechanical demands on the cutting edge. The insert is single-sided with four cutting edges, providing four index positions per insert.

Key Features

• Grade S40T with CVD TiCrN, Al2O3, and TiN multilayer coating for extended tool life in M and S material groups
• Square insert shape with 90-degree included angle and four cutting edges for four usable index positions
• Positive rake angle of 10 degrees with PM chip breaker for controlled chip formation
• Corner radius of 1.40 mm (0.0551 inches) providing a rounded cutting edge suitable for moderate surface finish requirements
• Screw-held, neutral-hand design compatible with R210 series cutter bodies
• Solid carbide substrate with CVD coating process for thermal and abrasion resistance

Compatibility

Designed for use with R210 series milling cutter bodies. ANSI and ISO code: R210-14 05 14E-PM S40T. Insert size code 140514. Compatible cutter series: R210.

Installation Notes

Installation is performed by a machinist or toolroom technician using the appropriate Torx or hex key for the clamping screw — consult the cutter body documentation for the correct screw torque procedure. Ensure the cutter body pocket and seating surface are free of chips and debris before seating the insert. Power down and lock out the spindle before indexing or replacing inserts. Do not mix insert grades or geometries within the same cutter body pass.
