Built from HSS-E cobalt high-speed steel with a bright uncoated finish, this tap is engineered for cutting internal threads in steel applications. It carries a plug chamfer for standard entry and is ground to a 2B class of fit with an H5\/H6 thread limit for consistent dimensional accuracy. Overall length is 3.811 inches with a thread length of 1.181 inches, making it suited for production and maintenance threading where controlled fit and tool life are priorities. Licensed machinists and toolroom technicians are the primary installers of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations in steel at a 5\/8-11 UNC pitch. The spiral point geometry pushes chips forward ahead of the tap, making it well suited for use in CNC machining centers, turret lathes, and manual tapping operations where chip evacuation into the through-hole is acceptable. It is part of the GUHRING Series 3901 and is appropriate for both production floor and job-shop environments requiring consistent 2B thread tolerances in ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHSS-E cobalt material for improved wear resistance and heat tolerance when threading steel\u003c\/li\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, optimizing through-hole threading efficiency\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides standard thread entry suitable for most production applications\u003c\/li\u003e\n  \u003cli\u003e2B class of fit with H5\/H6 thread limit for controlled dimensional accuracy\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 3 flutes, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading applications in steel at 5\/8-11 UNC.
