Spiral Flute Tap: 1/4-20 UNC, 3 Flutes, Semi-Bottoming, 2B Class of Fit, High Speed Steel, TIN Coated MPN:7606556

The Spiral Flute Tap by UNC is specifically designed for creating high precision threads with a reduced probability of thread stripping or breaking on steel or harder materials such as stainless steel, aluminum and titanium alloys. With its semi-bottoming flute design, this tap offers versatility in producing both through holes as well as blind and partial depth holes while offering consistent results at high production speeds. Additionally, the use of High Speed Steel with a TiN Finish ensures increased wear resistance, temperature stability, and cutting ability in challenging applications. This model is ideal for use in industries such as aerospace, automotive, military or general machining where superior thread forming and longevity is imperative to meet project deadlines with efficiency.
