Mill 1, a new line of indexable insert end mills that increase productivity, are offered in diameters from 0.97 in. to 8 in. They were designed to ramp aggressively so it delivers pocketing and hole drilling performances. The Mill 1 program offers at least 30 percent increase in maximum rotational speed, which enables further productivity gains in cutting softer materials such as aluminum and plastics. The new cutters are capable of producing square shoulders to closer tolerances. The program also offers higher maximum cutting speeds than competitors. The company installed the screw at an angle to eliminate shear forces enabling a 30 percent increase in rotational speed. The line can also produce a square shoulder to closer tolerances than competitive end mills. The Mill System is engineered to have more consistent and repeatable insert location, thus creating abilities to generate shoulders. Further gains are provided by four grades that offer improvements in performance. KC725M is a titanium carbonitride coated grade that provides performance in roughing and finishing most low carbon and alloys steels, stainless steels, and nickel-based alloys. KC935M is an aluminum oxide coated grade that offers high cutting speeds for gains on ferrous materials. KC522M is a titanium aluminum nitride coated grade designed for cutting higher strength materials such as tool steels and high temperature alloys. KC410M is a new grade with a titanium composite coated designed to reduce built-up edge that provides performance gains in machining low-silicon aluminum and plastics.
