Sumitomo U102077 Suminotch Grooving Insert SG3062 EH520V

Product Description

The SUMITOMO U102077 is a solid carbide grooving insert from the SumiNotch series, designed for precision grooving operations on CNC lathes and turning centers. It carries an EH520V grade designation with a TiAlN coating, which provides thermal resistance and wear protection across a wide range of workpiece materials. The insert has a neutral hand orientation, a cutting width of 0.062 inches, and a maximum depth of cut of 0.094 inches. With a cutting height of 0.344 inches and an overall width of 0.195 inches, it fits standard SumiNotch toolholders. This insert is sold individually and is installed by machinists and CNC technicians in production and job-shop environments.

The U102077 is suited for grooving applications on ferrous metals, non-ferrous metals, cast iron, high-temperature alloys, and stainless steel. Its universal primary workpiece material rating covers ISO material groups K, M, N, P, and S, making it a versatile option for shops running mixed-material programs. Typical applications include external and internal grooving, parting prep, and groove-to-shoulder work on turned components where consistent groove width and depth control are required.

Installation Notes

This insert is installed by qualified machinists or CNC technicians following standard insert-change procedures. Ensure the machine spindle is fully stopped and the toolholder is properly secured in the turret before seating or removing the insert. Use the appropriate insert clamp torque specified by the toolholder manufacturer for the SumiNotch system. Inspect the insert seat and clamping surfaces for chips or contamination before installation to maintain accurate positioning and prevent premature wear.
