Sandvik Coromant has introduced -M30 and -L50 geometry for its CoroMill 331 milling cutter.

The new geometries extend the cutter’s available applications. The latest additions to the portfolio comprise two new light-cutting, periphery-ground geometries for radius inserts to suit applications in the automotive, aerospace, and oil and gas sectors.

-M30 geometry is designed to optimize the groove milling of steel and cast iron automotive parts. Available for size 11 inserts with radius dimensions from 1.5 to 3 mm (0.059 to 0.118 in.), -M30 geometry is characterized by its light cutting action. This tough geometry is particularly beneficial for machine shops that want to boost security in weak setups 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 the -L50 geometry, which is intended for aerospace component machining as well as the machining of parts in the oil and gas industry. Offered for size 11 inserts with radius dimensions from 3 to 6.3 mm (0.118 to 0.248 in.), 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. Optimized for use in good operating conditions and heavy application areas, the available grade options are GC1040, GC2040 and S30T.

As a point of note, alongside -M30 and -L50, size 8, 11 and 14 inserts with a 4.0 mm (0.157 in.) radius are being made available as standard in -WM geometry. Again intended to improve the milling of automotive parts, grade options include GC1130, GC1020, GC3040 and GC4330.
