Walter 6169107 Indexable Drill Insert WKP35S Cvd

Product Description

The WALTER 6169107 is a solid carbide indexable drill insert designed for high-performance drilling in cast iron and steel applications. It carries the Tiger Tec series grade WKP35S and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for extended tool life under demanding cutting conditions. The insert uses chipbreaker geometry E57 and has four usable cutting edges on a square body, making it a practical choice for reducing per-edge tooling cost. With a 5.51 mm inscribed circle and a 90-degree included angle, it fits indexable drill toolholders designed around the ISO P4841P-2R-E57 designation. Licensed HVAC, metalworking, and machining professionals specify this insert for production drilling operations.

This insert is suited for drilling operations in both residential and commercial machining environments where the primary workpiece materials are cast iron and steel. The P35 and K35 material grades indicate it is optimized for ISO P and K material groups, covering a broad range of ferrous metals. It is commonly installed in indexable drill bodies used in CNC turning centers, machining centers, and drilling machines where consistent hole quality and tool life are priorities. The E57 chipbreaker promotes reliable chip evacuation in these materials.

Installation Notes

Indexable insert replacement is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool is secured before indexing or replacing the insert. Use the correct torque wrench and insert screw specified by the toolholder manufacturer - do not overtighten the clamping screw. Inspect the toolholder pocket and seating surface for wear or debris before seating the new insert.
