It carries an EH520V grade with a TiAlN coating for wear resistance across a broad range of workpiece materials. The insert features a 0.125 inch cutting width, a maximum depth of cut of 0.15 inches, and a neutral hand orientation. With a cutting height of 0.344 inches and a gage diameter of 0.375 inches, this insert is suited for tight-tolerance grooving applications where dimensional consistency and edge integrity are critical. Licensed machinists and CNC programmers select this insert for production turning cells.\u003c\/p\u003e\n\u003cp\u003eThe U102101 is intended for grooving and parting operations in both light and medium-duty turning applications. Its universal primary workpiece material classification covers a wide range of materials including cast iron, steel, stainless steel, aluminum, and heat-resistant superalloys, corresponding to ISO material codes K, M, N, P, and S. The SumiNotch series geometry supports stable chip control and consistent groove width in high-cycle production environments. This insert is a single-use, non-multi-use tool and is supplied individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eEH520V grade solid carbide construction with TiAlN coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e0.125 inch cutting width with a maximum depth of cut of 0.15 inches\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation compatible with standard SumiNotch toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius range of 0.005 to 0.010 inches for controlled edge geometry\u003c\/li\u003e\n  \u003cli\u003eLead angle of 3 degrees for stable entry and reduced lateral cutting forces\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO 13399 standards for tooling data interoperability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SUMITOMO SumiNotch series grooving toolholders that accept SG-style inserts with insert size code 3125.
