Built from high-speed steel with a bright uncoated finish, this tap features 5 flutes and a plug chamfer for progressive thread engagement. The extended overall length of 6 inches and a 0.9063-inch shank diameter make it suited for deep-hole tapping applications. A 0.6790-inch square drive size allows for positive torque transfer through a standard tap wrench or machine holder. Machinists and pipefitters working with threaded pipe connections in plumbing, HVAC, and industrial piping systems rely on this type of tap for field and shop fabrication work.\u003c\/p\u003e\u003cp\u003eThis extension pipe tap is used in applications requiring 3\/4-14 NPT internal tapered threads, common in pipe fittings, valves, manifolds, and pressure vessel ports. The plug chamfer style — with a moderate lead-in taper — makes it effective for through-hole tapping where thread engagement needs to begin gradually. The extended shank projection of 0.5650 inches provides the clearance needed to access recessed or countersunk bores. It is appropriate for use in ferrous and non-ferrous metals in both shop and field environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3\/4-14 NPT thread form for standard tapered pipe thread connections\u003c\/li\u003e\n\u003cli\u003e5-flute geometry for balanced chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides gradual thread engagement suitable for through-hole applications\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction offers durability across a range of metal materials\u003c\/li\u003e\n\u003cli\u003e6-inch overall length extends reach into deep or recessed bores\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish — no coating buildup concerns for tight-tolerance threads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 3\/4-14 NPT internal tapered pipe threads; compatible with standard tap wrenches and machine tapping setups that accept a 0.9063-inch shank diameter with a 0.6790-inch square drive.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is intended for use by machinists, pipefitters, and qualified tradespeople familiar with threading operations. Always ensure the workpiece is securely fixtured and the correct NPT tap drill size has been used before starting the tap. Apply appropriate cutting fluid for the material being tapped to reduce heat buildup and extend tool life. Do not force the tap if resistance increases suddenly — back off to clear chips and inspect the flutes for damage before continuing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-14 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.9063 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.6790 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.5650 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\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 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: MSC-04676078\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51721263087922,"sku":"MSC-04676078","price":130.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42e1cd214bbb0254dd04c82c57715540.jpg?v=1788575529","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04676078-extension-pipe-tap-3-4-14-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
