Built from high speed steel (HSS) with an oxide finish, it provides adequate lubricity and corrosion resistance for general-purpose tapping operations. The plug chamfer distributes the cutting load across several leading threads, making it well suited for through-hole applications. With an overall length of 2.125 inches and a thread length of 0.75 inches, this tap fits standard tap holders and extension arms used in manual and machine tapping setups. The H2 thread limit holds tight tolerances for 3B class of fit applications.\u003c\/p\u003e\u003cp\u003eThis tap is intended for through-hole tapping in materials including cast iron, ductile iron, stainless steel, and steel. It is commonly used in production and maintenance environments where 8-32 UNC fastener threads are required. Machinists, tool and die technicians, and maintenance mechanics use this tap with drill presses, CNC machining centers, and hand tap handles. The 2-flute design helps manage chip flow in through-hole applications by pushing chips forward ahead of the tap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8-32 UNC thread form with H2 thread limit for 3B class of fit tolerance control\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction handles a broad range of ferrous workpiece materials\u003c\/li\u003e\n\u003cli\u003eOxide finish provides baseline lubricity and mild corrosion resistance\u003c\/li\u003e\n\u003cli\u003ePlug chamfer distributes cutting load, optimized for through-hole tapping\u003c\/li\u003e\n\u003cli\u003e2-flute spiral point design pushes chips ahead to clear through-holes efficiently\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction for standard forward tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 8-32 UNC right-hand internal threads in cast iron, ductile iron, stainless steel, and steel workpieces.

Always ensure the pilot hole is drilled to the correct tap drill size for 8-32 UNC before tapping. Secure the workpiece firmly and apply cutting fluid appropriate for the workpiece material, particularly when tapping stainless steel. Do not reverse the tap to break chips in through-hole applications; the spiral point is designed to push chips forward.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32\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: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eOverall Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 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: High Speed Steel (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Ductile Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4131185\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747910680882,"sku":"4131185","price":30.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c49be1fd914a4115297a5795147b43b.jpg?v=1788886984","url":"https:\/\/voomisupply.com\/products\/kennametal-4131185-spiral-point-tap-8-32-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
