Sandvik Coromant 5853468 Milling Insert S30T R390

Product Description

The SANDVIK COROMANT 5853468 is a solid carbide milling insert in the R390 series, designed for shoulder milling and face milling applications in demanding materials. Manufactured to grade S30T with a TiAlN PVD coating, this right-hand insert carries a parallelogram shape with a 90-degree included angle and a positive 20-degree rake angle. The insert measures 3.59 mm thick and 6.80 mm in inscribed circle diameter, with a 0.80 mm corner radius. It features two cutting edges and uses a screw-in holding method. The ANSI and ISO code is R390-11 T3 08M-PM S30T. Licensed machinists and CNC tooling specialists install this insert in compatible shoulder mill bodies.

This insert is engineered for cutting stainless steel, superalloys, and titanium — workpiece material codes M and S. It is suited for both roughing and semi-finishing passes where controlled chip formation is critical. The PM chip breaker geometry supports stable cutting in interrupted or continuous cuts at moderate-to-aggressive feeds. Compatible cutter series include M-32 and R390 tool bodies. The positive rake design reduces cutting forces, which is particularly important when machining thin-walled or heat-sensitive aerospace and medical components. This insert is a single-sided type, with a maximum depth of cut of 10.00 mm.

Key Features

• Grade S30T solid carbide substrate with TiAlN PVD coating for heat and wear resistance in stainless and superalloy cutting
• Positive 20-degree rake angle reduces cutting forces on difficult-to-machine materials
• PM chip breaker geometry supports controlled chip evacuation across a range of feed rates
• R390 series parallelogram insert shape with 90-degree included angle for true shoulder milling
• 0.80 mm corner radius and two cutting edges per insert
• Screw-in holding method for secure, repeatable seating in compatible tool bodies

Compatibility

Compatible with R390 and M-32 series milling cutter bodies. Insert size code 11T308. Confirmed ANSI and ISO designation: R390-11 T3 08M-PM S30T.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Before changing inserts, ensure the spindle is fully stopped and the machine is in a safe, locked-out state per shop safety protocols. Use the manufacturer-specified torx or hex key to seat the clamping screw evenly — do not overtighten or cross-thread. Inspect the pocket seat and screw threads for chips or wear before installing a new insert to ensure proper seating and runout control.
