Built from high speed steel with a bright uncoated finish, this tap features a plug chamfer and four straight flutes for efficient chip evacuation during manual tapping operations. It carries a 3B class of fit and an H4 thread limit, making it appropriate for close-tolerance threading work. The overall length measures 6.375 inches, and the tap weighs 3.48 pounds. Machinists and toolroom technicians rely on this configuration when threading left-hand fastener applications where standard right-hand taps are not suitable.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in manual hand-tapping setups requiring a 1-1\/2-6 UNC thread form in the left-hand direction. It is suited to production and maintenance environments where oversized threading is not required. Typical applications include machine repair, tooling fabrication, and custom fastener work on heavy equipment or industrial machinery. The plug chamfer allows the tap to start easily in through-holes or sufficiently deep blind holes, and the four-flute straight-flute geometry works well in a range of metallic workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand thread direction for reverse-threaded fastener applications\u003c\/li\u003e\n\u003cli\u003e1-1\/2-6 UNC thread size with 3B class of fit and H4 thread limit for close-tolerance threading\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction for durability across a variety of materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for easy thread start in through-holes and deep blind holes\u003c\/li\u003e\n\u003cli\u003eFour straight flutes for effective chip clearing during hand tapping\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish with no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style hand tap for manual tapping operations requiring a 1-1\/2-6 UNC left-hand thread form in standard toolholding setups.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is intended for use by machinists and toolroom professionals using standard tap wrenches or T-handle wrenches. Always secure the workpiece firmly and ensure proper alignment before beginning the threading operation to avoid tap breakage. Apply appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Do not force the tap; back off periodically to break chips and clear the flutes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-1\/2-6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.375 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\u003eWeight\u003c\/strong\u003e: 3.48 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: JY4919601\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51723280810290,"sku":"JY4919601","price":244.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c801827bd073766202ec809496228ed.jpg?v=1788602573","url":"https:\/\/voomisupply.com\/products\/value-collection-jy4919601-hand-tap-1-1-2-6-unc-lh-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
