It carries a TM3501 grade designation with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, delivering thermal resistance and edge stability at elevated cutting speeds. The insert features a 35-degree diamond shape, a 1\/4-inch inscribed circle, a 1\/64-inch corner radius, and a positive rake angle of 17 degrees. The F1 chip breaker geometry produces sharp cutting edges suited for finishing and light roughing passes. Licensed machinists and CNC operators install this insert in standard VBMT-compatible toolholders for high-production turning operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is rated for primary use on stainless steel (ISO material code M, grade M30-M40) and secondary use on steel (ISO material code P). It supports back turning, facing, profiling, and general turning applications. The neutral hand designation makes it adaptable across a range of toolholder orientations. With two cutting edges per insert, it offers dual-sided utility, reducing per-edge tooling cost in production environments. It meets both ANSI and ISO standards and carries the ISO designation VBMT110304-F1.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic TiCN\/Al2O3\/Cr multilayer coating for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape with 5-degree relief angle (clearance code B)\u003c\/li\u003e\n  \u003cli\u003eF1 chip breaker geometry with sharp cutting edge style for finishing passes\u003c\/li\u003e\n  \u003cli\u003ePositive 17-degree rake angle reduces cutting forces on stainless steel\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert for extended tooling value\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VBMT-compatible toolholders conforming to ANSI and ISO VBMT110304-F1 standards.
