Spiral Flute Tap: 9/16-18, UNF, 3 Flute, Bottoming, 2B Class of Fit, Cobalt, Oxide Finish MPN:5973956

The spiral flute tap is designed for precise tapping operations that require smooth thread formation on both imperial (UNF) and metric threads such as 9/18 or M5 in materials like metal, plastic or aluminum with consistent results. Its cobalt construction offers durability against wear and heat during long usage, making it ideal for professional technicians or machinists who demand high precision machining at industrial settings. With three flutes and a bottoming taper, the tool ensures optimal chip ejection while creating strong threads without damage to fastener material, resulting in accurate results over time. Available in oxide finish coating that reduces friction between tool steel surface contact points minimizing workpiece scratches on stainless steel materials thus, improving overall productivity by reducing the amount of clean-up required before moving onto the next operation or component fabrication.
