Straight Flute Thread Mills

January 21, 2016

Scientific Cutting Tools Inc. (SCT) stocks UN thread mills for cutting from 4-40 up to 3-1/2-8, as well as NPT, BSPP and BSPT 1/16 to 2½ and up, according to the company based in Simi Valley, Calif. Except for staggered-tooth thread mills, all of SCT's solid-carbide, straight-flute thread mills are crest-cutting, and are used for cutting internal threads only.

Engineered for high performance, the tools are said to be both economical and long-lasting. SCT's straight-flute thread mills are made from premium sub-micron carbide on state-of-the-art CNC tool and cutter grinders, and are stocked with or without ALTiN coating.
