Kennametal 3324993 Milling Insert KC422M Solid Carbide

Product Description

The KENNAMETAL 3324993 is a solid carbide milling insert with a Titanium Diboride (TiB2) PVD coating, designed for high-performance milling of non-ferrous metals. Carrying ISO designation EDCT140404PDERLDJ and ANSI code EC1404ELDJ, this insert features a parallelogram shape, positive rake geometry, and a 15-degree relief angle. It provides two cutting edges per insert and uses a screw-holding method for secure clamping in compatible milling cutters. The LDJ chip breaker and honed cutting edge style promote clean chip evacuation and controlled edge engagement in aluminum and other non-ferrous workpiece materials. Licensed HVAC techs and machinists in metal-cutting trades rely on this insert for consistent performance in indexable tooling setups.

This insert is intended for milling applications where the primary workpiece material is non-ferrous metal, such as aluminum alloys and copper-based materials. It is suited for use in light to medium milling operations in both production shop and job-shop environments. The right-hand configuration and positive rake make it well matched to finishing and semi-finishing passes where surface quality and tool life are priorities. Compatible with the Mill 1-14 cutter series from Kennametal.

Key Features

• Solid carbide substrate with TiB2 PVD coating for non-ferrous metal cutting
• Positive rake geometry with 15-degree relief angle for reduced cutting forces
• LDJ chip breaker for controlled chip evacuation in aluminum and similar materials
• Two cutting edges per single-sided insert for extended tooling value
• Honed cutting edge style for improved edge stability and finish quality
• Screw-holding method for rigid, repeatable insert seating

Compatibility

Compatible with the Kennametal Mill 1-14 cutter series. Designed for right-hand tooling setups targeting non-ferrous metal workpiece materials per ISO and ANSI insert standards.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the milling cutter is fully de-energized and the spindle is locked before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer when tightening the insert clamping screw. Inspect the pocket seat for chips or debris before seating the insert to ensure proper contact and repeatability.
