This insert carries a CVD-applied TiCrN, Al2O3, and TiN multilayer coating under manufacturer grade 2040, providing thermal resistance and wear protection during continuous and interrupted cuts. It features a parallelogram shape with a positive rake angle of 20 degrees and a corner-rounded cutting edge style, contributing to smooth chip formation and reduced cutting forces. The insert measures 3.59 mm thick with an inscribed circle of 6.80 mm and accommodates a maximum depth of cut of 10.00 mm. It is sized to the 11T308 insert size code and is installed by licensed machinists and tooling professionals in CNC milling environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for machining steel, stainless steel, superalloys, and titanium, corresponding to ISO material application codes P, M, and S. The grade 2040 targets mid-to-high cutting speeds in these material groups, making it appropriate for production milling in aerospace, energy, and general manufacturing environments. The ML chip breaker geometry supports light-to-medium cutting conditions. The insert is right-hand oriented and single-sided, with a screw-type holding method. It is catalogued under ANSI and ISO code R390-11 T3 08E-ML 2040 and is compatible with cutter series M-32 and R390.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCrN, Al2O3, and TiN for extended tool life in difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003ePositive 20-degree rake angle reduces cutting forces and heat generation at the tool-workpiece interface\u003c\/li\u003e\n  \u003cli\u003eML chip breaker optimized for light-to-medium cutting conditions on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert, single-sided, right-hand orientation\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.80 mm (0.0315 inch) with corner-rounded edge style for improved edge stability\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut 10.00 mm; insert size code 11T308 for direct toolholder selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with cutter series M-32 and R390 toolholders.
