For machining in harder metals such as steel, the x.ceed coated end mill offers longer life and resists against abrasion. The tool is balanced with a shorter cut length, offering more stability and strength that is ideal for machining in steel. Note these tools are specifically designed for hard metals, so it is not as affective in softer alloys and plastics.
