This VNMG-style insert features a 35-degree diamond shape with a negative rake angle of 13 degrees and a neutral hand orientation. The insert carries SUMITOMO's AC8015P grade designation with an Absotech Platinum CVD coating, engineered for extended tool life and wear resistance when machining steel. The inscribed circle measures 3\/8 inches, insert length is 0.6535 inches, insert thickness is 3\/16 inches, and the corner radius is 1\/64 inches. It is installed by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning applications on steel workpieces, corresponding to ISO material group P. It is suited for P10 and P20 material grades, making it appropriate for general-purpose and semi-finishing operations on carbon steels, alloy steels, and cast steels. The ESU chip breaker geometry supports controlled chip formation across a range of depths of cut and feed rates typical in steel turning. It is used in both high-volume production turning and custom part machining where consistent surface finish and insert life are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAC8015P grade with Absotech Platinum CVD coating for wear resistance in steel cutting\u003c\/li\u003e\n\u003cli\u003e35-degree diamond insert shape (VNMG style) with negative rake for stable cutting edge\u003c\/li\u003e\n\u003cli\u003eESU chip breaker geometry for controlled chip evacuation in steel turning\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard VNMG toolholders using pin or screw holding\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO 13399 standards; ISO code VNMG160404N-SU\u003c\/li\u003e\n\u003cli\u003eMulti-use capable for both roughing and semi-finishing passes on steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in VNMG-style toolholders that accept pin or screw insert holding methods.
