Sandvik Coromant grooving

Sandvik Coromant has added the -M30 and -L50 insert geometry options for its CoroMill 331 milling cutter. These periphery-ground additions are meant for light cutting in automotive and aerospace applications. 

The -M30 geometry is designed for groove milling of steel and cast iron automotive parts. Available for size-11 inserts with radius dimensions ranging from 1.5 to 3.0 mm (0.059" to 0.118"), the insert geometry is characterized by its light cutting action, the company says. This geometry is said to be particularly beneficial for increasing security in weak setups or long-overhang applications. Grades available include GC1130, GC1020, GC3040 and GC4330.

The -L50 geometry is intended for machining of parts typical to aerospace and oil-and-gas applications. Offered for size-11 inserts with radius dimensions ranging from 3.0 to 6.3 mm (0.118" to 0.248"), light cutting action is said also to be the principal attribute of this geometry, making it suitable for materials such as stainless steel, nickel-based superalloys and titanium. Optimized for use in good operating conditions and heavy application areas, the available grade options include GC1040, GC2040 and S30T.

“Groove milling is one of the most common application areas within indexable milling, and the new geometries are specifically designed to meet the demands of machine shops looking to improve process security, quality and cost,” says Jenny Häll Jansson, the company’s global product manager for milling.


  • Start With The Right Speeds And Feeds

    Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.

  • Choose The Best Drill Point Geometry

    The more common twist drill point geometries often are not the best for the job at hand. By choosing the best point for the material being drilled, it is possible to achieve better tool life, hole geometry, precision, and productivity.

  • Successful Application Of Ceramic Inserts

    Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.
