Straight Flute Tap: 1/4-20 UNC, 3 Flutes, Bottoming, 3B Class of Fit, High Speed Steel, Bright/Uncoated MPN:1170200

The straight flute tap is a type of tapping tool designed for producing internal threads on fasteners, bolts or screws where high accuracy, surface finish, and precise sizing are imperative. The UNC thread series ensures compatibility with standard UNC thread forms in North America making it an essential tool across various industries such as automotive, aerospace, engineering, electronics, and construction among others. The 1/4-20 size allows the user to create smaller diameter threads with increased precision for delicate or intricate applications requiring tight tolerances. It comes equipped with 3 flutes that provide fast cutting action while minimizing vibration and heat buildup during operation; ensuring superior cutting performance even on harder materials like stainless steel or cast iron. Furthermore, the Bottoming tap design allows users to produce female threads up to the bottom of the hole providing uniform thread engagement without undercutting which can compromise the strength of the assembly. Lastly, its construction using high-speed steel delivers superior durability against wear and fatigue; ideal for continuous use across multiple projects, making it a top pick among protradesmen who value quality performance above all else.
