Spiral Flute Tap: 1/2-13 UNC, 3 Flutes, Modified Bottoming, 2B Class of Fit, Cobalt, Nitride Coated MPN:1301901903

The spiral flute tap is a precision cutting tool designed for drilling threads onto screws, bolts or nuts by creating an internal threaded surface through the hole. Made from durable cobalt alloy steel, it exhibits superior hardness and wear resistance enabling it to drill accurately while preventing breakage during use. It comes with a modified bottoming feature that allows for back tapping to produce bottoming threads in blind holes or counterbore operations ensuring no unthreaded surfaces remain. Additionally, the 2B class of fit surface treatment ensures smooth entry and exit while the nitride coating on its flutes prevents galling and welding onto materials allowing for effortless cutting during drilling. Overall, the spiral flute tap is suitable for various applications in industries such as aerospace or medical fields where precision threaded connections are required.
