Walter 6169132 Indexable Drill Insert P48448E57 WKP35S

Product Description

The WALTER 6169132 is a solid carbide indexable drill insert designed for high-productivity drilling operations in steel and cast iron workpieces. Manufactured in the Tiger Tec series, it carries the WKP35S grade with a CVD coating process, delivering thermal stability and wear resistance at demanding cutting speeds. The insert features a square shape with four cutting edges, an inscribed circle of 0.463 inches (11.76 mm), a thickness of 0.192 inches, and a corner radius of 0.028 inches (0.71 mm). The E57 chipbreaker geometry promotes controlled chip formation and reduced cutting forces. This insert is suited for use by machining professionals and CNC operators in production drilling applications.

The 6169132 is engineered for indexable drill toolholders requiring a square P48 insert style with a size code of 48 and an insert size designation of 6. It is intended for right-hand cutting direction. Primary workpiece materials include steel (ISO material code P) and cast iron (ISO material code K), covering a broad range of ferrous machining scenarios in job shop and production environments. The ISO code for this insert is P4841P-6R-E57 WKP35S. It conforms to both ANSI and ISO standards, making it compatible with tooling systems that reference either standard.

Key Features

• Solid carbide construction with CVD coating for extended tool life in steel and cast iron
• WKP35S grade within the Tiger Tec series provides high-temperature hardness and crater-wear resistance
• Four usable cutting edges per insert reduce per-edge tooling cost
• E57 chipbreaker geometry supports stable chip evacuation in drilling applications
• Square shape with 90-degree included angle and corner radius of 0.028 inches (0.71 mm)
• Meets ANSI and ISO standards for dimensional interchangeability

Compatibility

Designed for indexable drill systems accepting square P48 style inserts with insert size code 48 and a nominal width of 0.460 inches (11.75 mm). Compatible with right-hand cutting direction toolholders referencing ISO code P4841P-6R-E57 WKP35S.

Installation Notes

Insert seating and torque should follow the toolholder manufacturer specifications for the P48 pocket style. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key as specified by the toolholder manufacturer to avoid seat distortion. Inspect the insert pocket for wear or debris before seating a new edge.
