It carries the IC354 manufacturer grade with a PVD coating, making it suitable for demanding cutting applications where edge wear resistance and thermal stability are priorities. The cutting width is 3.10 mm (0.122 inches), the corner radius is 0.30 mm (0.0118 inches), and the relief angle is 7 degrees. The B chipbreaker geometry controls chip formation during groove cutting. This insert is installed by machinists and CNC operators in production turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is used in grooving and parting-off applications on metalcutting lathes. The neutral lead angle and neutral hand orientation make it suitable for straight plunge grooving where no side rake bias is required. It seats in compatible GTN-style insert toolholders with seat size 3. Typical applications include producing external grooves, undercuts, and parting cuts in ferrous and non-ferrous workpiece materials. The IC354 grade with PVD coating is commonly selected for steel and alloy steel workpieces in the C5 and C6 material grade range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGTN3B insert style with size code 3 seat for direct toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eIC354 grade with PVD coating for enhanced wear resistance in steel cutting\u003c\/li\u003e\n\u003cli\u003e3.10 mm (0.122 inch) cutting width for consistent groove sizing\u003c\/li\u003e\n\u003cli\u003e0.30 mm corner radius minimizes stress concentration at groove base\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle reduces flank contact and friction during plunge cuts\u003c\/li\u003e\n\u003cli\u003eNeutral lead angle and neutral hand for straight plunge grooving operations\u003c\/li\u003e\n\u003cli\u003eSingle-end insert design; replace when worn rather than index\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in GTN-style grooving toolholders with an insert seat size of 3.
