Built from high-speed steel, it carries a 3\/4-10 UNC thread form with a plug chamfer, which provides a gradual lead-in suited for through-hole tapping. The tap runs 4.25 inches overall with a 2-inch thread length, features 4 flutes for chip evacuation, and holds an H3 thread limit for consistent thread tolerance across production runs. Licensed machinists, toolroom operators, and maintenance mechanics reach for this tap when a reliable, standard-geometry UNC tap is required.\u003c\/p\u003e\u003cp\u003eThe OSG 1124902 is intended for general-purpose tapping operations in both manual and machine setups. Its plug chamfer makes it suitable for through holes where full thread engagement is needed before the chamfer exits the work. The H3 limit and 4-flute straight flute geometry support use in a range of ferrous and non-ferrous base materials. This tap is sold individually and is part of the OSG Series 101 line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-10 UNC thread form, right-hand cut\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for through-hole applications with gradual thread lead-in\u003c\/li\u003e\n\u003cli\u003e4 straight flutes for chip clearance in general-purpose materials\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for consistent tolerance control\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across a broad material range\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement, compatible with conventional flood or manual lubrication\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel.
