Walter 6171463 Indexable Drill Insert P48448E57 WKP25S

Product Description

The WALTER 6171463 is a square, 90-degree indexable drill insert designed for high-performance drilling operations in steel and cast iron. Manufactured from solid carbide and finished with a CVD coating in the WKP25S grade, this insert belongs to the Tiger Tec series and carries the P4840P-8R-E57 ISO code. The E57 chipbreaker geometry promotes controlled chip evacuation and consistent cutting action. With four usable cutting edges per insert, it delivers extended service life per piece and reduced cost per hole. It suits licensed machinists and tooling technicians running indexable drill bodies in production or job-shop environments.

This insert is intended for right-hand cutting applications in primary workpiece materials classified as steel (P) and cast iron (K), corresponding to ISO material grades P25 and K25. It is sized at insert size 8 with a 0.6500-inch inscribed circle and fits drill bodies accepting the P48448E57 seat geometry. Typical use cases include through-hole and blind-hole drilling on CNC machining centers and turning centers where consistent hole quality and tool life are required.

Installation Notes

Installation is performed by tooling technicians or machinists. Power down and lock out the machine spindle before seating or rotating any indexable insert. Use the manufacturer-specified torx or hex key to seat the clamping screw; do not use impact tools on insert screws. Inspect the pocket seat for chips or damage before installing a fresh edge, as debris in the pocket will cause premature insert failure or dimensional error.
