It cuts 8-32 UNC threads with a right-hand direction and features a plug chamfer for general through-hole and blind-hole applications. Built from high-speed steel and finished with a titanium nitride (TiN) coating, the tap offers improved wear resistance and extended tool life compared to uncoated HSS. With 4 flutes, a thread limit of H2, and a Class 3B fit, it produces threads suitable for close-tolerance fastener applications. Overall length is 2.125 inches with a 0.75-inch thread length. Licensed machinists, maintenance technicians, and tool-and-die professionals are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. It fits standard tap holders and extension handles designed for the number 8 tap size. The plug chamfer style makes it appropriate for starting threads in through holes as well as moderately deep blind holes where a starter lead is acceptable. It is commonly used in production machining, MRO maintenance shops, and fabrication environments where 8-32 UNC is a frequently required fastener thread.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-32 UNC thread form with right-hand cut and H2 thread limit for consistent Class 3B fit\u003c\/li\u003e\n  \u003cli\u003eTiN coating improves surface hardness and reduces friction during cutting\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles interrupted cuts and harder steels within rated material range\u003c\/li\u003e\n  \u003cli\u003e4-flute straight design works in both through-hole and blind-hole applications\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides 3-5 thread lead for reliable thread engagement on entry\u003c\/li\u003e\n  \u003cli\u003eCoolant-through: No — suitable for hand tapping and standard machine tapping without internal coolant supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel.

Ensure the workpiece is securely fixtured before starting the cut. Use an appropriate cutting fluid or tapping compound for the workpiece material to extend tap life and improve thread finish. Reverse the tap periodically when hand tapping in blind holes to clear chips and reduce the risk of breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 8-32 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\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\u003c\/strong\u003e: 2.125 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\u003eSquare Length\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.131 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.9338 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\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: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 102\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1014305\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728259973426,"sku":"1014305","price":23.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ae66bb2525865b876fad0d6f2dbeff3.jpg?v=1788690126","url":"https:\/\/voomisupply.com\/products\/osg-1014305-straight-flute-tap-8-32-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
