Straight Flute Tap: 1/4-56 UNS, 4 Flutes, Plug, 3B Class of Fit, High Speed Steel, Bright/Uncoated MPN:JY4840567

The straight flute tap's cutting geometry provides increased chip removal, reduced tool loading, and faster threading during metal machining processes compared to traditional spiral flute designs. Made from high speed steel (HSS), this versatile tap delivers durability in demanding industrial applications. With a 1/4 - 56 UNF standard coarse thread and 3B class of fit, it offers an optimal balance between tolerance and surface finish for precise fitment of assemblies across industries such as automotive engineering, aerospace manufacturing, heavy machinery, tool & die making or construction equipment. Its bright/uncoated surface ensures high visibility of cutting edges for better control while threading delicate materials like aluminum or brass.
