Straight Flute Tap: #4-40 UNC, 2 Flutes, Plug, 2B Class of Fit, High Speed Steel, Bright/Uncoated MPN:330021

The Straight Flute Tap #4-40 UNC 2 Flutes Plug 2B Class of Fit High Speed Steel Bright/Uncoated is an essential tool designed for precision machining applications that require fast, smooth and clean cutting when creating threaded holes. Made from high speed steel with a bright/uncoated finish ensuring durability and longevity even in tough operating conditions it delivers smooth, chip-free threads reducing risk of damage to materials being worked on. With its 2-flutes construction the tap clears chips faster thus reducing drag, while plug style allows for chip removal through the hole drilled before threading minimizing workpiece deformation ensuring consistent accuracy, it complies with UNC standard with a Class of fit rating of B making it ideal for use in both precision and heavy-duty manufacturing operations.
