Sandvik Coromant Releases New Insert Geometries for CoroMill 331

Introduced for CoroMill 331, Sandvik Coromant’s -M30 geometry is designed to optimise the groove milling of steel and cast iron automotive parts. Available for size 11 inserts offering radius dimensions from 1.5mm to 3mm, -M30 geometry is defined by its light cutting action. This tough geometry is particularly beneficial when machine shops want to boost security in weak set-up or long overhang applications, where it provides reliability and increased competitiveness. Grade availability includes GC1130, GC1020, GC3040 and the latest GC4330 steel milling grade.

Also launched is -L50 geometry, which is aimed at aerospace component machining, as well as parts in the oil and gas industry. Offered on size 11 inserts with radius dimensions from 3mm to 6.3mm, light cutting action is also the principal attribute of the tough and sharp -L50 geometry, making it suitable for materials such as stainless steel, nickel-based super alloys and titanium. Optimised for use in good operating conditions and heavy application areas, GC1040, GC2040 and S30T are the available grade options.

Alongside -M30 and -L50, size 8, 11 and 14 inserts with a 4mm radius are being made available as standard in -WM geometry, aimed at boosting the milling of automotive parts. Grade options include GC1130, GC1020, GC3040 and GC4330.

Apart from just groove milling, CoroMill 331 is a universal concept that can provide flexible, high-precision machining in numerous face, shoulder, and side and face milling operations across all industry segments. A large assortment covers an extensive choice of diameters, widths, insert geometries, corner radii and grades.
