Aluminum Reverse Tool MIL 6A60 L15 Alloy Internal Hole Thread Turning 6A55 Small Diameter Through-feed Machine
This MIL reverse micro internal threading tool series adopts solid tungsten carbide, specially developed for copper and aluminum workpieces. It offers 60° and 55° thread angles, 6mm shank and 15mm cutting depth, ideal for reverse small-bore threading on Swiss-type lathes.
Precision-lapped sharp thread cutting edges guarantee clean shearing and smooth chip flow for soft non-ferrous metals. The non-adhesive polished surface effectively suppresses built-up edge, ensuring precise thread profiles and mirror-grade surface finish in high-speed production.
Its specialized reverse structure perfectly fits the limited space inside narrow micro bores. The high-rigidity carbide body prolongs tool life, cuts tool-change downtime, and greatly improves mass production efficiency of tiny copper-aluminum threaded precision parts.
