Sandvik Coromant has expanded its CoroMill MS20 shoulder milling concept to include grade GC1230, specifically engineered for ISO P materials. This true 90-degree shoulder milling solution now delivers exceptional performance in steel machining, from roughing to finishing, with uncompromised security, versatility and productivity.

 

CoroMill MS20 combines high-quality cutter bodies with precision inserts to deliver excellent surface finishes and optimal wall quality in repeated shoulder milling. The robust cutter body provides tight tolerances on both axial and radial runout, enhancing component quality and reducing scrap rates. The inserts, manufactured using advanced pressing technology, offer superior dimensional accuracy, further enhancing insert tool life and component quality.

 

“CoroMill MS20 has already proven its value in ISO M and ISO S materials. With the addition of grade GC1230, it becomes a first-choice solution for ISO P applications, particularly in the general engineering and automotive industries,” says Sangram Dash, Global Product Manager for indexable milling tools at Sandvik Coromant. “Its versatility makes it ideal for repeated shoulder milling, face milling, linear and helical ramping, full slotting and plunging applications.”

 

Steel milling grade GC1230 features advanced coating and substrate technologies that provide excellent wear resistance and edge line security. Users will benefit from predictable tool life and consistent performance, even in demanding conditions. “The insert’s wear pattern is gradual and reliable, which translates into fewer unexpected tool changes and higher productivity,” Dash explains.

 

“You shouldn’t have to settle for compromises when it comes to shoulder milling”, concludes Dash. “Whether you prioritize secure and trouble-free machining, high productivity or increased cost-efficiency, CoroMill MS20 shoulder milling concept has got you covered.”

 

The CoroMill MS20 assortment includes cutter bodies ranging from 15.8 to 84 mm (with inch equivalents), along with a new cylindrical shank option with Silent Tools™ integrated damper, enhancing stability and performance in demanding operations. The insert range features geometries optimised for steel, stainless steel, and heat-resistant super alloys.
