Straight Flute Tap: #12-28 UNF, 4 Flutes, Taper, High Speed Steel, Gold/Oxide Coated MPN:BDNA-20771

The high-speed steel straight flute tap with a #12-28 UNF thread has a gold oxide coating to prevent galling and is ideal for tapping metals that demand high strength such as aluminum, steel or bronze. Its taper design delivers an exceptionally clean hole entry for precision threads by eliminating material ahead of the cutting edge and ensuring a more uniform pitch in machining operations. This taper tap fits into an existing hole by gradually enlarging it to form thread-like sections suiting industries like automotive, aerospace, manufacturing and construction who work with heavy equipment requiring strong materials for assemblies or repair work where they need both strength and precision in tooling pieces.
