Spiral Flute Tap: 1/4-28, UNF, 3 Flute, Bottoming, 3B Class of Fit, Vanadium High Speed Steel, Bright/Uncoated MPN:4130622

A premium bottoming tap suitable for a range of materials including aluminum, brass, and stainless steel, the spiral flute tap offers improved chip evacuation in comparison to straight flute taps. It's manufactured from vanadium high-speed steel, known for its durability and resistance against heat damage at higher speeds. Designed as a bottoming tap with three flutes, this tool efficiently produces smooth finishes on threaded parts and minimizes burrs, while an uncoated or bright surface reduces friction and increases lubricity when cutting threads. Ideal for applications in aerospace, automotive repair shops, machinery maintenance services, and electronics repair facilities, the spiral flute tap meets UNF standard (1/4-28) threading specifications.
