The STAR-MILL solid end mill line is the perfect choice for difficult-to-cut materials in the aerospace, power generation and general machining industries such as stainless steel and titanium alloys. The highly impressive metal removal rate of the STAR-MILL line is attributed to its uniquely designed 38°~45° high helix angle and unequal spacing of the cutting edges, which enables higher feed rates due to the minimal vibration and cutting noise when machining difficult-to-cut materials. Especially the new SED 7 end mill is ultra high productivity product due to its 7 flutes design and trochoidal machining. For difficult-to-cut materials, the new STAR-MILL means efficiency and productivity on the machine shop floor.
