Kennametal 4034882 Milling Insert WOEJ090512SRGD KC522M

Product Description

The KENNAMETAL 4034882 is a solid carbide trigon milling insert with ANSI/ISO designation WOEJ090512SRGD, manufactured in grade KC522M with a PVD-applied AlTiN coating. The insert features an 80-degree included angle, six cutting edges, a positive 15-degree rake angle, and a honed T-Land cutting edge style for consistent chip formation. At 0.213 inches thick with a 0.35-inch inscribed circle diameter and a 0.0480-inch corner radius, this double-sided insert is engineered for milling applications across steel, stainless steel, cast iron, and superalloys including titanium. It is held by screw and suits right-hand cutting configurations. Weighing 0.019 pounds per insert, it fits the KenFeed cutter series.

This insert is suited for face milling and shoulder milling operations on CNC machining centers handling a range of workpiece materials coded P, M, K, and S - covering carbon and alloy steels, stainless steels, cast irons, and superalloys and titanium. The GD chip breaker geometry promotes efficient chip evacuation during medium to semi-finish milling passes. The KC522M grade with AlTiN PVD coating delivers thermal resistance and wear protection in both dry and coolant-assisted cutting environments. Machinists and tool-room technicians working in production or job-shop settings will find this insert applicable across a wide range of metal-cutting scenarios on horizontal and vertical milling platforms.

Key Features

• Solid carbide substrate with PVD AlTiN coating for elevated thermal and abrasion resistance
• Six usable cutting edges per double-sided insert for extended tool economy
• Positive 15-degree rake angle with honed T-Land edge prep reduces cutting forces
• 0.0480-inch corner radius balances surface finish quality and edge strength
• GD chip breaker geometry suited for steel, stainless steel, cast iron, and superalloys and titanium
• Compatible with KenFeed cutter series using screw-clamp insert holding

Compatibility

Designed for use in the KenFeed cutter series. ANSI code WOEJ090512SRGD and ISO code WOEJ090512SRGD confirm compatibility with toolholders specifying the WOEJ insert style, size code 090512, and right-hand cutting geometry.

Installation Notes

This insert is installed and replaced by machinists or toolroom technicians using the appropriate Torx or hex key driver specified for the KenFeed cutter body screw. Power down and lock out the spindle before indexing or replacing inserts. Inspect the cutter pocket seating surface and screw for wear or damage before installing a new insert. Do not mix insert grades or geometries within the same cutter body during a single operation.
