It features 3 flutes with a plug chamfer, manufactured from vanadium high-speed steel (HSS-E) with a steam oxide coating for improved lubricity and corrosion resistance during cutting. The H2 thread limit holds a 3B class of fit, making it suitable for standard tolerance threaded assemblies. Right-hand cut with no coolant-through capability, this tap is sized for general-purpose hand or machine tapping in production and maintenance environments. Overall length is 2.126 inches with a thread length of 0.381 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used for threading through-holes in low-carbon steel, medium-carbon steel, hardened steel, and stainless steel. The spiral point design pushes chips forward ahead of the tap, making it well suited for through-hole applications in CNC machining centers, drill presses, and tapping heads. Machinists, tool-and-die makers, and maintenance technicians commonly use this size in fastener applications requiring standard 8-32 UNC thread form in both production and repair settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form, right-hand cut with H2 thread limit and 3B class of fit\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel (HSS-E) construction for improved wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and improves chip flow during cutting\u003c\/li\u003e\n\u003cli\u003ePlug chamfer (3-5 thread lead) suitable for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e3-flute spiral point geometry pushes chips forward, preventing chip packing\u003c\/li\u003e\n\u003cli\u003eCompatible with low-carbon, medium-carbon, hardened, and stainless steel workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping applications requiring 8-32 UNC thread form in ferrous materials including low-carbon steel, medium-carbon steel, hardened steel, and stainless steel, as specified in the product data.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a tap holder, tapping head, or rigid CNC tapping attachment appropriate for the shank diameter of 0.168 inches. Ensure the workpiece is securely fixtured and a suitable cutting fluid or tapping compound is applied for the material being tapped. For hand tapping, use a properly sized tap wrench and maintain alignment to prevent tap breakage. Always verify spindle speed and feed rate are appropriate for the workpiece material before machine tapping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\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: 0.381 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\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\u003eCoolant Through\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: 0.015 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: 1735901\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741433856306,"sku":"1735901","price":35.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/054a1be4112ffec1035b7f9f9ae8f8f2.jpg?v=1788831507","url":"https:\/\/voomisupply.com\/products\/osg-1735901-spiral-point-tap-8-32-unc-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
