Spiral Flute Tap: 3/4-10, UNC, 4 Flute, Semi-Bottoming, 2B & 3B Class of Fit, High Speed Steel, Bright/Uncoated MPN:TT76157

The Spiral Flute Tap: 3/4-10, UNC, 4 Flute, Semi-Bottoming, 2B & 3B Class of Fit, High Speed Steel, Bright/Uncoated is a specialized tool used for cutting internal threads on fasteners and dies with precision accuracy. Its four flutes provide exceptional chip removal and support for extended use in hard materials such as steel or stainless steel. The semi-bottoming style ensures uniform thread depth while eliminating damaged or misaligned threads due to over-tightening. The combination of 2B & 3B class of fit ensures optimal compatibility with both coarse (UNC) and fine (UNF) thread pitches, providing flexibility across different applications in automotive, aerospace, industrial machinery, or electronic systems manufacturing. Its high-speed steel construction ensures durability for tapping challenging materials at various speed ranges on CNC lathes or mills while the bright/uncoated finish allows easy identification of wear over time, ensuring reusability and reducing disposable tool costs.
