Walter 5535309 LNGX130708R-L88 WK10 Milling Insert

Product Description

The WALTER 5535309 is a solid carbide milling insert in the LNGX series, designed for high-performance milling of non-ferrous metals. It carries the ANSI and ISO designation LNGX130708R-L88 WK10 and is held to grade WK10 with an uncoated bright finish. The insert measures 0.5390 inches in length, 0.4330 inches wide, and 0.3050 inches thick, with a 1/32-inch corner radius. It features a negative rake angle of 28 degrees and a sharp cutting edge style. Licensed HVAC and machining trade professionals specifying tooling for aluminum, copper, and other non-ferrous materials will recognize this as a precision-ground, screw-held indexable insert built for consistent performance in production milling.

This insert is intended for milling applications on non-ferrous metals such as aluminum alloys, copper, and similar materials. It is compatible with Walter cutter series F2010 and F4041. The double-sided design and four cutting edges make it well suited to production environments where cost-per-edge efficiency matters. The L88 chip breaker geometry is optimized for the cutting conditions common in non-ferrous machining, and the right-hand configuration fits standard indexable milling tool bodies designed for that hand orientation.

Installation Notes

Installation is performed by qualified machinists or tooling technicians using the appropriate torx or hex key for the insert screw specified by the cutter body manufacturer. Ensure the cutter body pocket is clean and free of chips before seating the insert. Power down and lock out the machine spindle before indexing or replacing inserts. Follow the cutter body manufacturer's recommended clamping torque as specified in the tool body documentation - do not use values from other insert families.
