Kennametal 3849319 Milling Insert KC410 Solid Carbide Trigon

Product Description

The KENNAMETAL 3849319 is a solid carbide milling insert with ISO designation XNGJ0905ANFNLDJ3W, engineered for high-performance milling of non-ferrous metals. The insert carries a KC410 manufacturer grade and features a titanium diboride (TiB2) coating applied via PVD process, which delivers low friction and strong adhesion resistance when cutting aluminum, copper, and similar materials. The trigon insert shape provides an 80-degree included angle, and the wiper cutting edge style improves surface finish at elevated feed rates. With 6 cutting edges on a double-sided body, this insert extends tool life and reduces per-edge cost in production milling operations. It is installed and indexed by machining professionals in CNC milling environments.

This insert is designed for non-ferrous metal milling applications, including aluminum alloys, copper alloys, and other N-group workpiece materials. The LD chip breaker geometry controls chip flow in high-speed cutting conditions typical of aerospace, automotive, and general machining shops. The neutral hand orientation suits a wide range of milling orientations. The insert is compatible with the Kennametal Dodeka cutter series and is held in place by a screw-clamp insert holding method. It conforms to both ANSI and ISO indexable insert standards, making cross-referencing and toolholder matching straightforward for experienced machinists.

Key Features

• Solid carbide substrate with PVD-applied TiB2 coating for non-ferrous metal cutting
• 6 cutting edges on a double-sided insert body for extended tool life per insert
• Wiper cutting edge style for improved surface finish at higher feed rates
• LD chip breaker geometry optimized for non-ferrous chip control
• Trigon shape with 80-degree included angle and neutral hand orientation
• Compatible with Dodeka cutter series; screw-clamp insert holding method

Compatibility

Designed for use with the Kennametal Dodeka cutter series. Conforms to ANSI code XNGJ535ANFNLDJ3W and ISO code XNGJ0905ANFNLDJ3W. Screw-clamp toolholders accepting XNGJ-style inserts with a 0.625-inch inscribed circle are the correct match.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Use the appropriate Torx or hex key specified by the toolholder manufacturer to seat the clamping screw — do not overtighten, as solid carbide inserts are brittle and can crack under excessive clamp force. Inspect the toolholder pocket seating surface for chips or debris before installing a fresh insert. Verify insert orientation and cutting edge engagement before resuming operation.
