Sumitomo 144V422 Carbide Milling Insert Axmt

Product Description

The SUMITOMO 144V422 is a solid carbide milling insert in the AXMT style, designed for high-performance metal removal in demanding machining applications. Manufactured in a parallelogram shape with an 85-degree included angle, this insert carries the ACM200 grade with a CVD coating process for extended tool life. It measures 0.14 inches thick, with an inscribed circle of 0.26 inches and a cutting edge effective length of 0.472 inches. The EH chip breaker geometry and 11-degree relief angle make it well suited for finishing and semi-finishing passes on difficult materials. Licensed machinists and CNC tooling specialists are the primary installers.

This insert is intended for milling stainless steel and superalloys, applications that demand consistent edge integrity and thermal resistance. It is compatible with the WEX2000 cutter series and is a right-hand orientation insert. Typical use cases include face milling, shoulder milling, and contour operations on precision components in aerospace, medical, and industrial manufacturing environments where stringent surface finish requirements are standard.

Key Features

• Solid carbide construction with CVD coating for heat and wear resistance in stainless steel and superalloy cutting
• AXMT parallelogram insert style with 85-degree included angle for positive cutting action
• EH chip breaker geometry optimized for controlled chip evacuation on tough materials
• Maximum depth of cut of 10.00 mm (0.394 inches) for versatile roughing and semi-finishing
• Right-hand orientation with 11-degree relief angle for reduced cutting forces
• ACM200 manufacturer grade engineered for ISO material groups M and S

Compatibility

Compatible with the WEX2000 cutter series. Designed as a right-hand AXMT-style replacement insert for milling operations on stainless steel and superalloy workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the milling cutter body is fully de-energized and the spindle is locked before seating or replacing inserts. Use the appropriate torx or hex key as specified by the cutter body manufacturer to achieve proper insert clamping without over-torquing. Inspect the pocket seat and clamping wedge for wear or debris before installing a new insert.
