Milled solid carbide thread milling cutters use micro-grained carbide grades and TiCN coatings to increase tool life. The multi-spiral groove design eliminates machining chatter. The milling cutter design combines large tool diameters with precise thread profile corrections to ensure threading accuracy and expand the milling cross section to produce large thread lengths for API pipe threading.
Indexable insert thread milling cutters for machining tapered threads are hardened steel cutters, Weldon type shanks with CNC grinding or integral CAT50 shank with 3 stem sizes. The cutter is internally cooled and coolant is ejected radially from the cutting edge of the insert to optimize cooling and chip removal and improve thread quality and tool life. Grinding inserts are made of fine grain cemented carbide with TiN or TiAlN coating available. The design of the front and rear corners of the blade allows it to withstand a large chip load per tooth; the design of the blade shape enables free cutting, reduces radial cutting pressure, and ensures thread machining accuracy. Each blade has 4 usable cutting edges for longer blade life. Precisely machined high-precision tool holders on the steel end face of the tool body ensure precise positioning of the blade.
