Sandvik Coromant 5853564 Milling Insert S30T Carbide R245

Product Description

The SANDVIK COROMANT 5853564 is a solid carbide milling insert designed for high-performance face and shoulder milling in demanding materials. Manufactured in grade S30T with a PVD-applied TiAlN coating, this square-shaped insert features a positive rake angle of 10 degrees and a corner-rounded cutting edge style that reduces cutting forces and extends tool life. It carries the ANSI and ISO designation R245-12 T3 M-PL S30T, integrates with the R245 cutter series, and is held in place by a screw-clamp method. With four available cutting edges per insert, it delivers consistent performance across production runs in stainless steel and superalloy applications.

This insert is intended for use in the R245 shoulder milling cutter series and is suited for machining stainless steel, superalloys, and titanium — material grades M and S. It is appropriate for both roughing and semi-finishing passes where controlled chip formation and edge integrity are critical. The PL chip breaker geometry promotes efficient chip evacuation in these tough-to-machine materials. Machinists and CNC operators working in aerospace, medical, and industrial manufacturing will find this insert fits standard R245 toolholders without modification.

Key Features

• Solid carbide construction in manufacturer grade S30T for wear resistance in difficult alloys
• PVD TiAlN coating improves heat resistance and reduces built-up edge in stainless steel and superalloys
• Square insert shape with 90-degree included angle suits shoulder milling applications
• Positive 10-degree rake angle reduces cutting forces on the workpiece
• Four cutting edges per insert maximize value across the insert life
• PL chip breaker geometry supports controlled chip formation in gummy or work-hardening materials
• Right-hand cutting orientation with screw-clamp insert holding for secure seating under load

Compatibility

Designed for use with the Sandvik Coromant R245 cutter series. ANSI and ISO code R245-12 T3 M-PL S30T. Insert size code 12T3. Compatible with right-hand toolholders in the R245 series that accept this insert size and geometry.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom technicians. Always power down and lock out the machine before changing inserts. Use the manufacturer-specified torx or hex key to seat the clamping screw — do not overtighten, as this can crack the carbide body. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert to ensure proper seating and runout control.
