Manufactured from high speed steel with a bright finish, this tap features 5 flutes and a plug chamfer configuration. The interrupted thread design reduces cutting torque and helps clear chips during the tapping operation, making it well-suited for threading tough materials. Overall length is 3.75 inches, with a thread length of 1.75 inches and a shank diameter of 1.125 inches. It is used by machinists, pipefitters, and plumbing contractors who need accurate NPT threads in production or maintenance settings.\u003c\/p\u003e\u003cp\u003eThis tap is intended for creating standard NPT tapered pipe threads in ferrous materials including alloy tool steel and carbon steel. The plug chamfer provides a moderate lead-in, making it appropriate for through-hole pipe threading applications where a starting tap has already been used or where full thread engagement is needed near the entry point. The 5-flute design improves surface finish and distributes cutting load across more cutting edges compared to fewer-flute configurations. Typical applications include threading pipe fittings, manifold ports, and hydraulic or pneumatic block passages in industrial and mechanical service environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInterrupted thread geometry reduces cutting torque and improves chip evacuation in tough ferrous materials\u003c\/li\u003e\n\u003cli\u003e5 flutes distribute cutting load and improve thread finish quality\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides moderate lead-in suitable for through-hole NPT threading\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction delivers durability in alloy tool steel and carbon steel applications\u003c\/li\u003e\n\u003cli\u003eBright finish with no coating interference on cutting edges\u003c\/li\u003e\n\u003cli\u003eRegular hook geometry compatible with standard tapping chucks and equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 1 to 11-1\/2 NPT tapered pipe threads in alloy tool steel and carbon steel workpieces.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct NPT tap drill size before beginning the threading operation. Use an appropriate cutting fluid for the workpiece material to extend tap life and improve thread quality. Inspect the tap for chipping or wear before each use and do not force a worn or damaged tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1 to 11-1\/2 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 11.5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHook\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.843 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.678 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Tool Steel, Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CLEVELAND\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C64103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51714435547442,"sku":"C64103","price":536.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bcc902b38facc33f236da8796eff93d3_5593e9f3-21a0-4e49-8058-3018c3d5fc30.jpg?v=1788501445","url":"https:\/\/voomisupply.com\/products\/cleveland-c64103-pipe-tap-1-11-2-npt-5-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
