Manufactured from vanadium high-speed steel (HSS-E) with a steam oxide coating, this tap offers improved lubricity and corrosion resistance during threading operations. It features 3 flutes and a plug chamfer, which eases entry into through-hole applications by distributing cutting load across several leading threads. The H2 thread limit holds tight tolerance control on the finished thread form. With an overall length of 2.126 inches and a thread length of 0.374 inches, this tap is suited for short-reach threading in production and maintenance environments. Licensed machinists and toolroom technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in through-hole threading applications on hardened steel, low-carbon steel, medium-carbon steel, and stainless steel workpieces. The spiral point design pushes chips forward ahead of the cutting zone, making it well suited for machine tapping on CNC machining centers, drill presses, or tapping arms where chip evacuation ahead of the tap is practical. It is a common choice for production threading of small-diameter fastener holes in fabrication, repair, and assembly operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-36 UNC thread form with H2 thread limit for consistent tolerance control\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel (HSS-E) construction for durability in ferrous materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating improves lubricity and reduces galling during threading\u003c\/li\u003e\n\u003cli\u003ePlug chamfer distributes cutting load for smooth entry in through-hole applications\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in machine tapping\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 3-flute design, non-coolant-through construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in hardened steel, low-carbon steel, medium-carbon steel, and stainless steel.

Always apply cutting fluid appropriate for the workpiece material before and during tapping. Ensure the spindle speed and feed rate match the tap manufacturer recommendations for the material being threaded. Inspect the tap for chipping or wear before each use, as a damaged tap can destroy the workpiece thread.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-36 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.126 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.374 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.168 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hardened Steel, Low-Carbon Steel, Medium-Carbon Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1727701\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754902192434,"sku":"1727701","price":35.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd9f216103e3456fcda55c312d07dcd0_c8382d80-4e81-4230-acbe-9042377a2f16.jpg?v=1788949660","url":"https:\/\/voomisupply.com\/products\/osg-1727701-spiral-point-tap-8-36-unc-3-flute-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
