Each of SCT’s coolant through port tools has coolant holes to either 3 or 5 of the tool’s flutes because having an uneven number helps reduce chatter. Coolant lowers the surface temperature of the cutting zone making our port tools better equipped to deal with the extremely high temperatures that occur when machining a part.…

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 2 ½ and up. All of our solid carbide straight flute thread mills, except for staggered tooth thread mills, are crest-cutting and are used for cutting internal threads only. Engineered for high performance, these…

Long Reach Thread Mills have three teeth and a helical flute that provide reduced side cutting pressure. The first tooth roughs, the second and third finish. This allows for the efficient cutting of extremely deep threads in small sizes. These tools cut internal threads only Thread Mills cut a thread using helical interpolation. Helical interpolation…
