Straight Flute Tap: 1/4-28 UNF, 4 Flutes, Taper, 2B/3B Class of Fit, High Speed Steel, Uncoated MPN:TT82935

The straight flute tap is manufactured from high speed steel with uncoated finish that provides excellent hardness for superior wear resistance and rigidity. Its 4 flutes provide ample chip extraction whilst reducing vibration during the tapping process, allowing precise holes to be drilled with minimal deviation. With a class of fit rating of 2B/3B, this tap ensures maximum accuracy when tapping in materials such as aluminum, brass, mild steel, and other alloys. Its size of 1/4-28 UNF is suitable for smaller diameter threads used across diverse industries such as automotive, general machining, and light industrial applications. It features a 47-degree threading angle allowing the operator to achieve maximum success in tapping.
