Machinists and DIYers, this 1/2-13 UNC spiral point plug tap is serious business for your threading needs! Made from high-speed steel with a durable titanium coating, this tap can handle tough materials like stainless steel and aluminum without wearing out quickly. The H2 tolerance ensures precise, accurate threads every time, which is crucial for professional results. The 3-flute design is genius - it provides efficient chip removal so you don't get clogging during the tapping process. With a 35mm thread length and round shank with square end, this tap works perfectly with tap collets, drilling machines, tapping machines, and CNC equipment. The spiral point design helps push chips forward rather than back into the hole, resulting in cleaner threads and less breakage risk. Important tip: this is really designed for machine use with proper overload protection rather than hand tapping, since uneven force can damage the tap. Whether you're working in a professional shop or have a serious home machining setup, this quality tap delivers reliable performance that makes threading operations smoother and more precise. Your toolbox needs this professional-grade threading tool that'll handle your toughest jobs with ease!
