MGMN300-G Carbide Grooving Inserts 3.0mm PVD Coated for Lathe Cut-Off 10Pcs

Key features

• PERFECT FIT FOR 3.0MM HOLDERS: Premium MGMN300-G indexable carbide grooving inserts engineered to seat precisely in standard MGEHR/L (external) and MGIVR/L (internal) grooving cut-off tool holders.
• ADVANCED PVD COATING: Finished with a high-performance Physical Vapor Deposition (PVD) layer for excellent thermal stability, low friction, and significantly extended tool life under heavy workloads.
• G CHIPBREAKER GEOMETRY: Features a sharp, positive cutting edge with low cutting resistance that shears soft and gummy materials cleanly, making it ideal for aluminum, copper, brass, and other non-ferrous metals as well as stainless steel.
• PRECISE 3.0MM WIDTH: Engineered with an exact 3.0mm cutting width, making these double-sided indexable blades ideal for grooving, profiling, and parting-off operations on CNC or manual lathes.
• MULTI-MATERIAL APPLICATION: A tough tungsten carbide substrate paired with a heat-resistant PVD coating delivers smooth, efficient performance on aluminum, copper, brass, and other non-ferrous metals, plus stainless steel.

Premium PVD Coated MGMN300-G 3.0mm Carbide Grooving Inserts (10pcs) Upgrade your lathe turning and parting performance with these industrial-grade MGMN300-G indexable carbide inserts. Engineered for high-precision operations, this 10-piece set is an essential choice for high-volume CNC machine shops, production lines, or precision DIY lathe projects. Excellent Wear Resistance & PVD Coating Each insert features a micro-grain tungsten carbide substrate protected by an advanced PVD (Physical Vapor Deposition) coating. This super-hard protective layer withstands the intense heat generated during high-speed cutting, effectively resisting built-up edge (BUE) and premature chipping when machining tough materials like stainless steel or alloy steel. Superior Chip Control with G-Geometry The standout feature of the "-G" geometry is a sharp, positive cutting edge with low cutting resistance that shears soft and gummy materials cleanly, making it ideal for aluminum, copper, brass, and other non-ferrous metals as well as stainless steel. This design keeps chips under control, prevents tangling around the tool holder, and ensures a smooth, professional surface finish on your workpiece. Specific
