It carries the QD-NG0300-0004-CM 1145 designation, indicating a neutral-hand, clamp-held insert with a 3.00 mm cutting width (0.1181 inch), a 0.40 mm corner radius, and a 7-degree relief angle. The TiAlN\/AlCr2O3 PVD coating in Manufacturer Grade 1145 with the CM chipbreaker geometry targets controlled chip formation in medium to finishing cuts. Machinists and toolroom professionals install these inserts in compatible CoroCut QD toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for parting off and grooving work in production turning environments, including both light industrial and precision job-shop settings. The CM chipbreaker geometry is intended for finishing and medium-duty cuts where chip control and surface finish are priorities. The PVD-applied TiAlN\/AlCr2O3 coating supports cutting performance in a range of workpiece materials including steel and stainless. Insert seat size G matches the corresponding G-size CoroCut QD toolholder pockets. Minimum order quantity is 10 units; each package contains 1 insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate, Manufacturer Grade 1145 for consistent edge toughness\u003c\/li\u003e\n\u003cli\u003e3.00 mm cutting width (0.1181 inch) with QD-N insert style and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eTiAlN\/AlCr2O3 PVD coating for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003eCM chipbreaker for controlled chip evacuation in finishing to medium-duty cuts\u003c\/li\u003e\n\u003cli\u003e0.40 mm corner radius for defined grooving geometry\u003c\/li\u003e\n\u003cli\u003e7-degree relief angle reduces rubbing and supports clean parting cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroCut QD series toolholders with an insert seat size G.
