Built from high-speed steel with a bright\/uncoated finish, this tap features 4 flutes and a bottoming chamfer, making it well suited for threading holes that require full thread depth close to the bottom. It carries a 3B class of fit and an H4 thread limit, delivering consistent dimensional control for precision threaded assemblies. With an overall length of 5.125 inches and a thread length of 2.5 inches, this tap is sized for standard machine tapping applications. A shank diameter of 0.8 inches and a square size of 0.6 inches allow secure chuck or holder engagement.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in machine tapping operations on aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. It follows the OSG Series 101 specification and is a right-hand thread tool. Typical applications include production tapping on CNC machining centers, drill presses, and tapping heads where a bottoming chamfer is required to achieve full thread engagement near the bottom of a blind hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip management in a variety of materials\u003c\/li\u003e\n\u003cli\u003eH4 thread limit for consistent 3B class-of-fit tolerances\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand thread cutting, 1-14 UNS thread form\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish compatible with standard cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct production tap for machine tapping setups requiring a 1-14 UNS bottoming tap with a 3B class of fit.
