It carries a multilayer CVD coating of TiC, TiCN, and TiN under the HC335 manufacturer grade, providing wear resistance and thermal stability across a range of workpiece materials. The insert features a 3\/4 inch inscribed circle, a 3\/64 inch corner radius, a 90-degree square shape, and an 11-degree relief angle with a positive rake geometry. It is installed by machinists and toolroom technicians in production and job-shop turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning ferrous and stainless workpiece materials, corresponding to ISO material groups P and M. The neutral hand orientation makes it compatible with both left- and right-hand toolholders. The KENDEX series designation and SPG633 style code indicate use in clamp-style toolholders with a P tolerance and G clearance code. Typical applications include roughing and semi-finishing passes where controlled chip flow and edge integrity are required. Maximum depth of cut is 0.0492 inch (1.25 mm).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eHC335 grade rated for ISO P and M workpiece materials including steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e3\/4 inch inscribed circle with 90-degree square insert shape for versatile toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e3\/64 inch (0.0470 inch) corner radius suitable for moderate finishing and semi-roughing operations\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry with 11-degree relief angle reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method with no chip breaker (style code N) for straightforward insert seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in clamp-style SPG-seat toolholders conforming to the KENDEX series SPG633 insert style.
