Built from high-speed steel with a bright, uncoated finish, it cuts 1-1\/2-12 UNF right-hand threads to a 3B class of fit with an H4 thread limit. Six flutes provide a balance of chip clearance and cutting edge support, making this tap well suited for threading ferrous and non-ferrous materials in production and maintenance environments. Overall length is 6-3\/8 inches with a 3-inch thread length. Machinists and tool-and-die tradespeople are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shop, manufacturing, and industrial maintenance settings where UNF fine-thread holes are required at the 1-1\/2-inch diameter. The plug chamfer — typically 3 to 5 threads of lead — makes it appropriate for starting threads in through-holes or continuing threads after a taper tap. It is compatible with standard tap handles, manual tapping machines, and CNC rigid-tapping operations at appropriate speeds and feeds for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-1\/2-12 UNF thread form for fine-pitch internal threading\u003c\/li\u003e\n  \u003cli\u003e6-flute geometry balances chip evacuation with cutting edge rigidity\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides 3-5 thread lead for general-purpose through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction maintains edge integrity across a wide range of materials\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows for easy visual wear inspection during service\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit and 3B class of fit meet standard tolerance requirements for most industrial applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose straight flute tap for 1-1\/2-12 UNF internal threading applications.

Apply consistent, even pressure and back off periodically to break chips, especially in blind-hole applications. Inspect the tap for wear or chipping before each use; a damaged tap can seize or break in the hole. Follow shop safety procedures and use eye protection when operating tapping equipment.\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\/2-12\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: 6\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: 6-3\/8 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: 2.09 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-04489654\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51720748564786,"sku":"MSC-04489654","price":171.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b4444ede36857265eb6674e38dc4cf4.jpg?v=1788568577","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04489654-straight-flute-tap","provider":"Voomi Supply","version":"1.0","type":"link"}
