Spiral Point Tap: 5/16-18 UNC, 2 Flutes, Plug Chamfer, 2B/3B Class of Fit, High-Speed Steel, Steam Oxide Coated MPN:2750276

The Spiral Point Tap 5/16-18 UNC is a top choice among professional machinists and tool operators seeking to create high-precision threaded holes in various materials such as steel or stainless steel with minimum burrs, deviations, or workpiece stress. It features two flutes for superior chip removal, a 3B class of fit for precise dimensional accuracy during operation, and a plug type design to facilitate quick plug tap usage or blind hole tapping. The high-speed steel construction offers outstanding wear resistance, heat dispersion, and durability while the oxide coating enhances lubricity, corrosion resistance, and torque transmission during cutting. This spiral point tap is ideal for use in automotive, aerospace, electronics, and general manufacturing sectors where high-precision threading operations are necessary to create secure attachments or smooth component transitions, reducing post processing steps needed for cleanup, rethreading, or deburring while saving time, costs, and effort.
