Sumitomo U102102 Grooving Insert SG3125CB EH520V Suminotch

Product Description

The SUMITOMO U102102 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries the EH520V grade with a TiAlN coating that supports dry and semi-dry cutting at elevated speeds and temperatures. The insert features a 0.185-inch cutting width, a maximum depth of cut of 0.150 inches, and a cutting height of 0.344 inches. The right-hand orientation and SG insert style place it in the SumiNotch series, which is engineered for controlled chip formation and consistent dimensional accuracy in interrupted and continuous grooving cuts. Installation and setup are performed by machinists and CNC tooling technicians.

This insert is suited for grooving applications across a broad range of workpiece materials, including carbon steel, stainless steel, aluminum, nonferrous alloys, and superalloys. The universal primary workpiece material classification covers material codes K, M, N, P, and S, making this insert appropriate for job shops and production environments where multiple material types are machined on the same tooling setup. It is sized for use with compatible SumiNotch toolholders accepting the SG-3125 insert format.

Key Features

• Solid carbide construction with TiAlN coating for high-heat and high-speed grooving
• 0.185-inch cutting width with a maximum depth of cut of 0.150 inches
• Corner radius range of 0.005 to 0.010 inches for controlled edge geometry
• Right-hand, single-use insert with CB chip breaker geometry
• Lead angle of 3 degrees reduces lateral cutting forces during plunge grooving
• Compliant with ANSI and ISO 13399 tooling data standards

Compatibility

Designed for use with SumiNotch series toolholders accepting the SG-3125 insert format. Compatible with workpiece materials classified under ISO material codes K, M, N, P, and S. ANSI code SG-3125R-CB.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the toolholder pocket is clean and free of chips or debris before clamping the insert to maintain proper seating and edge engagement. Follow the toolholder manufacturer's clamping torque specifications and do not exceed the rated maximum depth of cut for this insert geometry.
