It cuts an 8-32 UNC right-hand thread and is built from high-speed steel for durability under repeated use. With a bottoming chamfer, this tap is suited for producing threads to the bottom of blind holes where through-tapping is not possible. The 3-flute design provides adequate chip clearance while maintaining good thread form. Overall length is 2.125 inches with a thread length of 0.75 inches. This tap carries an H7 thread limit for close tolerance work and is intended for use by machinists, tool and die tradespeople, and maintenance mechanics.\u003c\/p\u003e\u003cp\u003eThis tap is applied in production and maintenance machining environments where precise, close-tolerance internal threads are required in blind holes. It is rated for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. Applications include threading tapped holes in fixtures, machine components, and fabricated assemblies. The straight flute configuration makes it well suited for short-chipping materials such as cast iron and aluminum alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer allows threading to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction handles a broad range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eH7 thread limit suits close-tolerance tapping applications\u003c\/li\u003e\n\u003cli\u003e3-flute straight design provides chip clearance in short-chipping materials\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 8-32 UNC specification\u003c\/li\u003e\n\u003cli\u003eCompact overall length of 2.125 inches fits standard tap handles and drill press setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard replacement or stock tap for 8-32 UNC bottoming applications in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists using a standard tap handle, T-handle wrench, or machine tapping head rated for the tap size. Always ensure the pilot hole is drilled to the correct tap drill diameter for 8-32 UNC before tapping. Apply appropriate cutting fluid for the material being tapped to extend tool life and improve thread quality. Avoid forcing the tap; back off periodically to break chips and prevent binding or breakage.\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\u003eChamfer Type\u003c\/strong\u003e: Bottoming\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\u003eThread Limit\u003c\/strong\u003e: H7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.125 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: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\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: 103\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: 1019902\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739316617522,"sku":"1019902","price":24.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d08637df45c3a2889d68b931d7fd4748.jpg?v=1788813040","url":"https:\/\/voomisupply.com\/products\/osg-1019902-straight-flute-bottoming-tap-8-32-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
