Built from high-speed steel with a bright uncoated finish, the set delivers consistent thread form across a range of material hardnesses. The 6-flute geometry provides additional cutting edges compared to standard 4-flute taps, improving chip load distribution and surface finish in through-hole and blind-hole applications. The set covers Class of Fit 2B and 3B, making it suitable for both standard commercial tolerances and closer-fitting thread assemblies. Overall length is 5.75 inches with a thread length of 2.5625 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap set is used by machinists and maintenance professionals cutting large-diameter fine-pitch threads in applications such as hydraulic fittings, mechanical assemblies, and structural fastener repairs. The UNF thread standard and right-hand thread direction make it appropriate for conventional bolt and nut configurations across industrial, automotive, and general manufacturing environments. Thread limit H4 accommodates standard plating allowances and tolerance requirements for commercial-grade threaded connections.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/4-12 UNF thread form, right-hand cut\u003c\/li\u003e\n  \u003cli\u003e6-flute design distributes cutting load and improves chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles a wide range of material hardnesses\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids on most materials\u003c\/li\u003e\n  \u003cli\u003eClass of Fit 2B and 3B for commercial and close-tolerance thread applications\u003c\/li\u003e\n  \u003cli\u003e3-piece set includes taper, plug, and bottoming tap configurations for full thread-cutting flexibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard machine tapping setups and hand-tapping operations requiring 1-1\/4-12 UNF thread form with H4 thread limit and Class of Fit 2B or 3B.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eUse by a qualified machinist or maintenance technician. Always secure the workpiece fully before tapping and apply appropriate cutting fluid for the base material being threaded. Power down any machine tool and confirm zero-energy state before loading or changing taps.
