Kennametal 1535836 Milling Insert SDET120412PDERGB KC725M

Product Description

The KENNAMETAL 1535836 is a solid carbide milling insert in the SDET series, identified by ISO code SDET120412PDERGB and manufactured in grade KC725M. It features a square insert shape with a 90-degree included angle and a right-hand cutting orientation. The insert carries a multilayer PVD coating of TiN, TiCN, and TiN, which improves wear resistance and edge life in demanding milling applications. With a 15-degree relief angle and a 5-degree rake angle, it is engineered for productive metal removal in steel, stainless steel, superalloys, and titanium. Licensed machinists and CNC tooling specialists install this insert in compatible milling toolholders for face, shoulder, and pocket milling operations.

This insert is suited for use in industrial milling operations targeting steel (ISO P), stainless steel (ISO M), superalloys, and titanium (ISO S) workpiece materials. The SDET120412PDERGB designation covers a broad range of roughing and semi-finishing applications where edge security and coating durability are priorities. With a maximum depth of cut of 0.5000 inches and a chip breaker designation of GB, it handles moderate to aggressive chip loads in production environments. It is typically used in CNC machining centers running high-feed or conventional face milling programs.

Key Features

• Square insert shape with 90-degree included angle for shoulder and face milling versatility
• GB chip breaker geometry optimized for steel, stainless steel, superalloys, and titanium
• 15-degree relief angle and 5-degree rake angle for positive, free-cutting action
• Right-hand cutting orientation with screw-type insert holding method
• Maximum depth of cut of 0.5000 inches supports both roughing and semi-finishing passes

Compatibility

Designed as a direct-fit replacement for SDET-series milling toolholders accepting an inscribed circle of 0.5000 inches and a screw-mount insert holding method. Compatible with tooling systems specifying material grades C5, C6, or C7 carbide inserts.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to seat the clamping screw to the proper engagement without stripping the insert hole. Handle solid carbide inserts with care to avoid chipping the cutting edge prior to use.
