Sandvik Coromant 5853542 Milling Insert S40T Carbide R210

Product Description

The SANDVIK COROMANT 5853542 is a solid carbide milling insert manufactured to ANSI and ISO standards under the designation R210-09 04 14E-PM S40T. It carries a CVD-applied multilayer coating of TiCrN, Al2O3, and TiN, which provides thermal resistance and edge toughness during interrupted and continuous milling operations. The insert is square in shape with a positive rake angle of 10 degrees, a corner radius of 1.40 mm (0.0551 inches), and a thickness of 4.50 mm (0.1772 inches). With four cutting edges and a PM chip breaker geometry, it is engineered for controlled chip formation in demanding milling applications. Licensed machinists and CNC mill operators working with stainless steel, superalloys, and titanium components are the primary installers of this insert.

This insert is designed for use in the R210 cutter series and targets milling of stainless steel (ISO material group M) and superalloys including titanium (ISO material group S). Typical applications include face milling and shoulder milling operations on aerospace, medical, and energy sector workpieces where heat resistance and edge stability are critical. The neutral hand orientation makes it suitable for a range of toolholder configurations within the R210 platform. Maximum depth of cut is 1.00 mm (0.0472 inches), making it well suited for light to moderate radial engagement passes on difficult-to-machine materials.

Key Features

• Solid carbide substrate with CVD multilayer TiCrN, Al2O3, and TiN coating for thermal and wear resistance
• Positive rake angle of 10 degrees reduces cutting forces on stainless steel and superalloy workpieces
• Four usable cutting edges per insert for extended tool life economy
• PM chip breaker geometry promotes reliable chip control at moderate cutting parameters
• Square insert shape with 90-degree included angle for shoulder milling applications
• Meets ANSI and ISO dimensional standards under code R210-09 04 14E-PM S40T

Compatibility

This insert is dimensionally compatible with the R210 cutter series as specified by the manufacturer. The ANSI and ISO code R210-09 04 14E-PM S40T identifies the exact toolholder family and seat geometry required. No other specific compatible cutter models or replaced part numbers are identified in the available product data.

Installation Notes

Installation is performed by CNC machinists or toolroom technicians using a torx or hex key driver to seat the insert via the screw-holding method. The machine spindle must be fully stopped and the cutter body secured before seating or removing inserts. Inspect the insert pocket and clamping screw for debris or damage before installation to ensure proper seating and prevent edge chipping. Follow the cutter manufacturer's recommended clamping torque specification for the R210 seat size, as over- or under-torquing the screw can cause insert rocking or premature failure.
