Sandvik Coromant Shoulder Milling Solution Provides Versatile Performance

Sandvik Coromant introduces the CoroMill MS20, a 90-degree shoulder milling solution. Designed for roughing to finishing in stainless steel and heat-resistant super alloys (HRSAs), it can provide security, versatility and productivity, according to the company.

CoroMill MS20 features optimized geometries tailored for different ISO materials, enabling higher edge-line security. CoroMill MS20 inserts are said to exhibit a predictable and gradual wear pattern on the cutting edge, even in demanding applications.

The combination of high-quality cutter bodies and inserts can deliver optimal surface finish and wall quality in repeated shoulder milling applications. The cutter body is also said to provide high levels of dimensional control, closely matching the nominal diameter with tighter tolerances on axial and radial runout. According to Sandvik, this can result in improved component quality, fewer rejections and extended insert tool life.

Manufactured using a new pressing technology, the inserts optimize dimensional accuracy, which can further enhance component quality and insert tool life. The high accuracy of the direct-pressed CoroMill MS20 insert enables it to replace periphery ground geometries with similar performance.

The assortment encompasses cutter bodies in the range of 15.8-84 mm with inch equivalent cutters, along with inserts featuring optimized geometries for stainless steel and HRSA applications.

“CoroMill MS20 is the new single-sided, two-edge solution for true 90-degree shoulder milling applications in ISO M and ISO S materials, especially for the aerospace and oil and gas industries,” says Sangram Dash, global product application specialist for indexable milling tools at Sandvik Coromant. “CoroMill MS20 excels in repeated shoulder milling, face milling, linear and helical ramping, full slotting and plunging applications.”
