Sandvik Coromant 5853467 Milling Insert S30T Carbide R390

Product Description

The SANDVIK COROMANT 5853467 is a solid carbide milling insert in the R390 series, designed for high-performance face and shoulder milling applications. Manufactured to grade S30T with a TiAlN PVD coating, this insert delivers wear resistance and thermal stability when cutting difficult materials. It features a parallelogram shape with a positive 25-degree rake angle and a corner-rounded cutting edge style, producing reduced cutting forces and smooth chip flow. The insert size code is R390-11 T3 08M-PL S30T, with a 3.59 mm thickness and a 6.80 mm inscribed circle diameter. It is installed by machinists and toolroom technicians working in precision metal-cutting environments.

This insert is suited for milling stainless steel, superalloys, and titanium alloys, corresponding to ISO material groups M and S. It fits the R390 and M-32 cutter series and is intended for right-hand cutting. The maximum depth of cut is 10.00 mm, making it appropriate for both roughing and semi-finishing passes in demanding production environments. It is a single-sided insert held in place by a screw-lock method, compatible with toolholders designed around the R390-11 T3 08M-PL geometry.

Key Features

• Solid carbide substrate with TiAlN PVD coating for thermal resistance on stainless and superalloy workpieces
• Positive 25-degree rake angle reduces cutting forces and heat generation
• Corner radius of 0.80 mm (1/32 inch) with corner-rounded cutting edge style for smooth entry
• Maximum depth of cut: 10.00 mm
• PL chip breaker geometry optimized for ISO M and S material groups
• Right-hand, single-sided insert with screw-lock holding method
• Meets ANSI and ISO standards; ANSI/ISO code R390-11 T3 08M-PL S30T

Compatibility

Designed for use with the Sandvik Coromant R390 and M-32 cutter series. Compatible toolholders must accept the R390-11 T3 08M-PL insert geometry. Verify cutter body designation and pocket configuration before installation.

Installation Notes

This insert is installed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the correct torx or hex key to torque the clamping screw to the toolholder specification provided by the cutter body manufacturer — do not estimate torque by feel. Inspect the insert pocket for damage or debris before seating the new insert to ensure full contact and accurate indexing.
