Spiral Flute Tap: 1/2-13, UNC, 4 Flute, Bottoming, 2B Class of Fit, Cobalt, TICN Finish MPN:CU999400.5013

The spiral flute tap is a tapping tool designed to create threads in materials such as aluminum, brass, or steel. Made from high-quality cobalt steel, this tap is ideal for use on harder metals where conventional taps would quickly wear down. Its UNC 1/2-13 thread type makes it compatible with standard machinery and components, providing versatility in the workshop. The four flutes provide an efficient chip evacuation route for faster and smoother operation while reducing heat buildup. The bottoming feature allows users to produce mating threads with a stronger thread form at the bottom of the hole, providing superior strength. With its 2B class of fit and TICN finish, this tap ensures a tight and accurate thread fit for reliable performance. Industries such as automotive, aerospace, and general manufacturing benefit from the precision capabilities of this spiral flute tap.
