It produces a 1\/2-13 UNC thread profile with a right-hand thread direction and a plug chamfer for standard through-hole tapping applications. Built from vanadium high-speed steel (HSS-E) with a bright finish, it carries an H5 thread limit and a 2B class of fit. With an overall length of 3.374 inches and a thread length of 0.921 inches, this tap is sized for typical production and maintenance threading work. Installation is performed by licensed machinists, toolroom technicians, and maintenance mechanics.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole threading operations in both production and job-shop environments. Its three-flute spiral point geometry pushes chips forward ahead of the cutting zone, making it effective in through-holes where chip evacuation would otherwise be a concern. Rated for use in aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and hardened steel, it covers a broad range of workpiece materials encountered in general machining and maintenance applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/2-13 UNC thread form with right-hand cutting direction\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for standard through-hole tapping\u003c\/li\u003e\n\u003cli\u003eThree-flute spiral point geometry pushes chips forward for cleaner through-hole cuts\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel (HSS-E) construction for durability across diverse workpiece materials\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and 2B class of fit for consistent thread tolerance\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating for straightforward re-sharpening\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping of 1\/2-13 UNC threads; compatible with aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron workpieces as stated by the manufacturer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed and operated by qualified machinists or maintenance mechanics familiar with threading operations. Always ensure the workpiece and tapping fixture are securely clamped before beginning. Use an appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and improve thread finish.
