Sumitomo 1P4W014 Lnex Carbide Milling Insert ACM300

Product Description

The SUMITOMO 1P4W014 is a solid carbide milling insert carrying the LNEX130608PNERG designation and ACM300 manufacturer grade. It features a PVD-applied TiAlN/AlCrN dual-layer coating designed to sustain cutting performance in demanding milling applications. The insert has a rectangular shape with a negative rake angle of -6 degrees and a right-hand cutting orientation. At 12.6 mm long, 13 mm wide, and 6.4 mm thick, with a corner radius of 0.03 mm, this insert is built for precision milling where tight geometry and coating integrity directly affect tool life and surface finish. Licensed HVAC, machining, and metalworking professionals install these inserts into compatible indexable milling cutter bodies.

This insert is intended for milling stainless steel and superalloys, material groups M and S in ISO classification. The ACM300 grade uses a medium-grain carbide substrate paired with a PVD coating process, which maintains a sharp edge at the cutting geometry while resisting the elevated temperatures and built-up edge common when cutting austenitic stainless and nickel-based superalloys. The maximum depth of cut is 12.00 mm, and the effective cutting edge length is 0.3660 inches. The G chip breaker geometry controls chip formation in these tough-to-machine materials. This insert is compatible with the TSX cutter series.

Key Features

• ACM300 medium-grain solid carbide substrate for toughness in M and S material groups
• PVD-applied TiAlN/AlCrN coating resists heat and wear in stainless steel and superalloy milling
• Negative rake angle (-6 degrees) with right-hand cut for stable, controlled engagement
• G chip breaker geometry promotes reliable chip evacuation in difficult materials
• Corner radius of 0.03 mm supports precise edge geometry and fine surface finish
• Compatible with TSX cutter series for straightforward indexing

Compatibility

Designed for use with the TSX cutter series. Primary workpiece materials are stainless steel and superalloys (ISO material groups M and S). Insert size code is 1306; insert style is LNEX.

Installation Notes

Insert seating and torque should follow the cutter body manufacturer specifications for the TSX series. Power down and lock out the spindle before indexing or replacing inserts. Use proper insert handling tools to avoid contact with the cutting edges, which can cause chipping or personal injury. Verify seating and clamp integrity before resuming cuts.
