Walter 5055689 Milling Insert WK10 Solid Carbide

Product Description

The WALTER 5055689 is a solid carbide milling insert in the ADHT series, designed for high-precision metal removal in milling applications. It carries the WK10 manufacturer grade and features an uncoated bright finish, making it well suited for cutting non-ferrous metals where sharp, clean edges are critical. The insert has a parallelogram shape with an 85-degree included angle, a positive rake angle of 20 degrees, and a 15-degree relief angle. With a corner radius of 0.0315 inches and a sharp cutting edge style, it delivers accurate, controlled cuts at the tool-workpiece interface. Installation is by screw-holding method.

This insert is intended for milling of non-ferrous metals in precision machining environments. It is a right-hand, single-sided insert with two cutting edges, suitable for use in compatible milling cutter bodies in production or maintenance machining settings. The G88 chip breaker geometry supports efficient chip evacuation during non-ferrous cutting operations. The insert size code is 1204, placing it in a standard category used in many industrial milling platforms. It is compatible with WALTER cutter series F2010, F4042, and F4138.

Installation Notes

Installation is performed by qualified machinists or tooling technicians using the screw-hold clamping method. Ensure the cutter body is fully de-energized and the spindle is locked before seating or replacing inserts. Use the correct torque driver specified by the cutter body manufacturer when tightening the clamping screw. Inspect the insert pocket for wear or debris before seating the new insert to ensure proper contact and runout.
