Spiral Point Tap: 5/8-18 UNF, 4 Flutes, Plug Chamfer, 3BX Class of Fit, High-Speed Steel-E-PM, GLT-1 Coated MPN:CU20A611.5049

This spiral point tap delivers fast and easy drilling of blind holes into hardened steels or high-strength alloys using standard hand tools due to its proprietary four flute design that removes chips smoothly without breaking or wobbling in operation, producing high precision threads without skiving or damage to the component. The UNF thread type ensures compatibility with industrial grade fasteners for a secure connection in demanding applications while the powdered metal construction provides heat and wear resistance. Its GLT-1 finish reduces friction for smoother entry into the workpiece surface while preserving durability under harsh working conditions. This tap is widely used across industries such as aerospace, automotive, manufacturing, and military where precision machining and high torque demands are required to create strong and accurate threads.
