Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this tap delivers reliable thread-cutting performance in ferrous and non-ferrous metals. The plug chamfer — typically 3 to 5 threads — makes it suitable for through-hole and most blind-hole applications where adequate clearance exists below the thread. With 4 flutes and an H2 thread limit, it holds close tolerances suited to standard-fit threaded assemblies. Machinists, maintenance technicians, and tool-and-die workers keep this tap in regular rotation for production and repair threading operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general metalworking, MRO maintenance, and machine shop environments. It threads 1\/2-20 UNF holes in steel, aluminum, brass, and similar materials. The plug chamfer style makes it one of the most versatile chamfer options, starting easily in a hole while still cutting to near-full depth. It is suited to manual hand-tapping with a tap wrench as well as low-speed machine tapping on drill presses, mills, or CNC equipment when used with appropriate tapping fluid or cutting oil.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-20 UNF thread profile for fine-pitch unified national thread applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3-5 lead threads for versatile through-hole and blind-hole use\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides toughness and wear resistance across common workpiece materials\u003c\/li\u003e\n  \u003cli\u003e4-flute design promotes chip control and thread accuracy\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit ensures close-tolerance fits for standard threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — ready to use with cutting oil or tapping fluid without coating compatibility concerns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or stock tap for any application requiring a 1\/2-20 UNF right-hand internal thread.

Always apply cutting oil or tapping fluid during the tapping operation to extend tool life and improve thread quality. Back the tap off periodically when hand-tapping to break chips, particularly in steel. Secure the workpiece firmly and align the tap perpendicular to the hole face before applying torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04464202\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691512660274,"sku":"MSC-04464202","price":25.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e35154dac153d8573466e39a981aa297.jpg?v=1788286291","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04464202-straight-flute-tap-1-2-20-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
