The Hertel Straight Flute Tap delivers precision threading performance for demanding applications. Designed specifically for 5/8-18 UNF threading operations, this professional-grade tap features four straight flutes that efficiently evacuate chips while creating clean, accurate threads. The bottoming chamfer design allows you to thread all the way to the bottom of blind holes, maximizing usable thread depth in your workpieces. Constructed from high-quality high-speed steel with a bright, uncoated finish for excellent visibility during operation, this tap provides the durability needed for consistent results across multiple threading operations. The 3B class of fit ensures standard clearance for general-purpose applications, while the 3-13/16" overall length offers excellent reach and control. This right-hand tap is ideal for machinists, toolmakers, and manufacturing professionals who require precise threading capabilities in various materials. The straight flute design makes this tap particularly effective for through-hole applications where chip evacuation is critical to achieving clean, accurate threads.
