Manufactured to insert style SEET with a square shape and size code 13T3, this insert features an ACM300 grade substrate with a PVD coating process that enhances wear resistance and edge retention at elevated cutting temperatures. The insert measures 13.40 mm in cutting edge effective length and 3.97 mm in thickness, with an inscribed circle of 0.5000 inches. A 20-degree relief angle supports free-cutting action and reduces cutting forces on difficult workpiece materials. Machining shops and tool-room professionals working in precision milling operations are the primary installers and end users of this insert.\u003c\/p\u003e\u003cp\u003eThe 144W980 is optimized for primary workpiece materials classified as stainless steel and superalloys, corresponding to material codes M and S. These material groups are common in aerospace, medical device, and industrial pump manufacturing, where tight tolerances and difficult-to-machine alloys demand reliable insert performance. The G chip breaker geometry aids chip control in these materials. This insert is compatible with the WGX cutter series, which governs the seat geometry and axial pocket configuration required for proper seating and clamping.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eACM300 grade solid carbide substrate with PVD coating for wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eSquare SEET insert style in size 13T3 with a 20-degree relief angle for free-cutting geometry\u003c\/li\u003e\n\u003cli\u003e13.40 mm cutting edge effective length and 3.97 mm thickness for consistent depth-of-cut control\u003c\/li\u003e\n\u003cli\u003eG chip breaker geometry optimized for stainless steel and superalloy chip control\u003c\/li\u003e\n\u003cli\u003eCompatible with WGX cutter series toolholders\u003c\/li\u003e\n\u003cli\u003e0.5000-inch inscribed circle diameter meeting standard seat specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the WGX cutter series.

Power down and lock out the spindle before changing inserts. Inspect the insert pocket seat for chips or debris before seating the new insert, as contamination will affect insert stability and surface finish.
