Ground from high speed steel (HSS) with a bright, uncoated finish, this tap produces 1-11\/2 NPTF threads over a 1-3\/4 inch thread length. The short projection design suits tight-clearance applications where tool reach must be minimized. With 5 flutes, the tap distributes cutting load evenly and handles chip evacuation in through and blind pipe thread applications. Licensed plumbers, pipefitters, and maintenance machinists use this tap when threading pipe fittings, manifolds, and hydraulic or pneumatic ports to NPTF standards.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading pipe connections in residential and commercial plumbing, HVAC refrigerant line fittings, hydraulic assemblies, and pneumatic system ports where a pressure-tight NPTF thread is required. The 1-11\/2 thread size targets larger-diameter pipe connections. Short projection geometry makes it practical on drill press setups, tapping heads, or hand-tap drivers in confined spaces or on production fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNPTF thread form produces pressure-tight, dryseal pipe threads without sealant\u003c\/li\u003e\n  \u003cli\u003e5-flute design distributes cutting forces and supports chip evacuation\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides hardness and wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suits general-purpose tapping where coating is not required\u003c\/li\u003e\n  \u003cli\u003eShort projection style fits tight-clearance and fixture-mounted tapping applications\u003c\/li\u003e\n  \u003cli\u003e1.1250 inch shank diameter with 0.8430 inch square drive for standard tap wrenches and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap holders, tapping heads, and hand tap wrenches accepting a 1.1250 inch shank with a 0.8430 inch square drive.

Secure the workpiece firmly before tapping and use a cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically to break chips and prevent tap breakage, especially in blind-hole applications. Always verify thread fit with a NPTF thread gauge before assembly on pressure-bearing systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-11\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Short Projection\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\u003eShank Diameter\u003c\/strong\u003e: 1.1250 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.8430 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.5650 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: R859560-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51734329557298,"sku":"R859560-S","price":308.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/74f5cf5345d26704b4dc2a7cd53f9730_890d1968-d666-4757-945b-ef7fc3c1d75b.jpg?v=1788762534","url":"https:\/\/voomisupply.com\/products\/hertel-r859560-s-nptf-pipe-tap-1-11-2-5-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
