Walter 7487806 Indexable Drill Insert WKP35S Carbide

Product Description

The WALTER 7487806 is a solid carbide indexable drill insert designed for use in indexable insert drills on CNC machining centers and turning centers. Manufactured in the WKP35S grade, this insert offers a square P284 style geometry with a 96-degree included angle and four usable cutting edges, maximizing cost efficiency per insert. At 0.5900 inches in width and length, it carries ISO code P2841S-6N-E57 and meets both ANSI and ISO standards. It is engineered for demanding hole-making operations where consistent bore quality and tool life are critical.

This insert is suited for drilling cast iron and steel workpieces, covering ISO material groups K and P. The WKP35S grade is a general-purpose carbide grade that handles interrupted cuts and varying surface conditions common in ferrous machining. Typical applications include production drilling in automotive, structural, and general mechanical manufacturing environments where high repeatability and edge durability are required. A licensed machinist or CNC operator handles installation and indexing.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. Always power down and lock out the machine spindle before seating or indexing inserts. Use the correct Torx or hex key specified by the tool body manufacturer to secure the insert clamp screw - do not overtighten by feel alone; follow the tool body documentation for fastener guidance. Inspect the insert pocket and clamping seat for chips or debris before seating a new insert.
