Manufactured from high-speed steel with a bright uncoated finish, this tap cuts a 1-1\/2-6 UNC right-hand thread to a 3B class of fit with an H4 thread limit. It features 4 flutes and a 3-inch thread length with an overall length of 6.375 inches. Machinists and toolroom technicians use this tap in manual or machine tapping operations on steel, cast iron, aluminum, and similar machinable materials.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance machining environments requiring a coarse unified thread in larger-diameter workpieces. Its bottoming chamfer — typically 1 to 2 thread leads — allows threading to the bottom of a blind hole, making it the final tap in a tapping sequence when full thread depth is required. It is appropriate for use in machine shops, repair facilities, and industrial manufacturing settings working with 1-1\/2-inch coarse-thread fastener specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-6 UNC thread form, right-hand cut, for coarse unified threads in larger-diameter applications\u003c\/li\u003e\n  \u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003e3B class of fit with H4 thread limit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes for chip clearance in through and shallow blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of machinable metals\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — suitable for use with cutting fluids on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for any application requiring a 1-1\/2-6 UNC bottoming tap with a 3B class of fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists using a tap wrench, tapping head, or CNC rigid-tapping setup. Always ensure the pilot hole is drilled to the correct tap drill diameter for a 1-1\/2-6 UNC thread before tapping. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. When tapping blind holes, clear chips frequently to prevent tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Right Hand\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.375 inches\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.14 pounds\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-04489613\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51698224365874,"sku":"MSC-04489613","price":183.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/68635be22039909aaed35d9bc719cf78.jpg?v=1788359609","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04489613-straight-flute-tap-1-1-2-6-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
