It cuts a 12-24 UNC right-hand thread with a plug chamfer that eases entry and distributes cutting load across the leading threads. The tap is manufactured from HSS-E cobalt high-speed steel, which provides elevated heat and wear resistance compared to standard HSS. It carries a bright, uncoated finish and is built to a 2B class of fit. With an overall length of 2.382 inches and a thread length of 0.630 inches, it is suited for use in standard CNC machining centers, drill presses, and hand-tapping operations where straight-through chip flow is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading applications in steel workpieces. The spiral point geometry pushes chips forward ahead of the tap rather than packing them in the flutes, making it the correct choice when the hole passes completely through the material. It is commonly used in production machining and maintenance-repair-operations environments where 12-24 UNC fastener threads are required. The Series 3901 designation identifies it within the GUHRING standard tap line. Machinists, tool-and-die makers, and MRO technicians are the primary users of this tool.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHSS-E cobalt construction improves heat and wear resistance in steel applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load across the lead threads for controlled entry\u003c\/li\u003e\n  \u003cli\u003e2B class of fit meets standard UNC tolerance requirements for general-purpose fastener threads\u003c\/li\u003e\n  \u003cli\u003eH3\/H4 thread limit provides controlled oversize for consistent fit after plating or finishing\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping chucks and CNC rigid tapping cycles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in steel workpieces requiring a 12-24 UNC, 2B class of fit thread.
