Machinists working with tough materials like stainless steel or titanium, listen up. This is a professional-grade M10 x 1.50 solid carbide thread mill. It's designed to cut full-form internal threads in one pass, which is way more efficient and accurate than using taps, especially in hard metals. It's coated with TiAlN (Titanium Aluminum Nitride), a super-hard coating that reduces heat and extends tool life dramatically. Made in the USA by Onlinecarbide, a trusted name. Part number 9310150. Brand new in its protective packaging. You'll need a CNC machine with helical interpolation capability to use it. If you're doing precision threading work, this tool is an investment that pays off in quality and speed.
