Spiral Point STI Tap: 1/4-28 UNF, 3 Flutes, Plug, Powdered Metal, Oxide Finish MPN:1715401

The spiral point sti tap is a high-quality tool designed to make threading operations simpler for machinists and professionals working on precision parts assembly using metallic materials often used in automotive or aircraft industries with an UNF size of 1/4 - 28 pitch standard, three flutes engineered into the cutting head provide a smooth feed rate making it suitable for thread milling applications where accuracy is critical, hence this plug type version ensures no through-hole drilling which prevents damages or inconsistencies in holes' tolerance during the threading process also its construction uses powder metal coating increases its hardness and wear resistance on the insert's edge making it suitable for both tapping softer materials like aluminum but can easily cut threads in steel offering more durability when cutting high tensile strength components with ease hence time-saving by minimizing breaks while using this tap due to fatigue. Additionally, this model comes with an oxide finish coating that enhances corrosion resistance properties increasing the overall performance and tool's longevity which reduces maintenance needs hence saves costs over time making it ideal for professional workshops involved in threading operations regularly requiring top-notch tools providing consistency in quality.
