SGS Tool Company (Munroe Falls, OH), the industry leader in high performance tool design, introduces a new end mill that provides precision performance and high production rates with minimal chatter. Series 7 High Performance End Mills feature variable pitch fluting geometry that provides improved chatter suppression, longer tool life, better surface finishes and higher productivity rates. Manufactured with a rigid construction using certified premium micro-grain carbide, Series 7 High Performance End Mills also deliver reduced harmonics and reduced radial side deflection allowing for improved side wall straightness. In a chatter comparison test performed in 4140 Alloy Steel @ 28HRc, a conventional long end mill produced maximum amplitude of 79, as compared to the Series 7, which produced maximum amplitude of 18. The capacity for superior chatter suppression means Series 7 High Performance End Mills deliver a better surface finish, as well. In a finish cut comparison using the Mitutoyo Surftest Surface Finish Analyzer, the conventional long end mill resulted in 58.5 Ra, compared to the Series 7 End Mill at 9.7 Ra. Exceptional for use in a variety of materials up to 45 Rc, Series 7 High Performance End Mills are available in ball and square end sizes and are coated with SGS’ exclusive Ti-NAMITE-A® (AlTiN) coating for increased tool life and higher productivity.
