It features 2 flutes and a taper chamfer for easy thread entry, and is manufactured from high-speed steel (HSS) with a bright\/uncoated finish. The taper chamfer distributes cutting forces gradually, making it well suited for through-hole and blind-hole applications in softer metals. With an overall length of 1.6875 inches and a thread length of 0.375 inches, this tap is sized for fine-pitch, small-diameter threading work. A 3B class of fit and H1 thread limit ensure dimensional accuracy within standard tolerance requirements. Installation is performed by machinists and maintenance professionals using standard tap handles or machine tapping equipment.\u003c\/p\u003e\n\u003cp\u003eThis tap is rated for use in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. It is suited for both hand tapping and machine tapping operations where a 1-64 UNC thread form is required. The right-hand thread direction and taper chamfer make it a standard choice for production and maintenance shops handling small fastener thread repairs or new thread creation in light-gauge components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-64 UNC thread form with 64 threads per inch for fine-pitch small-diameter applications\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer distributes entry load across multiple threads for smoother cutting starts\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides durability across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e3B class of fit with H1 thread limit for consistent, within-tolerance threads\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish with right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003e2 straight flutes for chip clearance in through-hole and short blind-hole work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for tapping 1-64 UNC internal threads in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces.

Secure the workpiece and ensure the tap is aligned perpendicular to the hole before beginning the threading operation. Apply appropriate cutting fluid for the material being tapped to reduce heat and extend tap life. Do not force the tap if resistance increases unexpectedly, as small-diameter taps are susceptible to breakage under side load or misalignment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-64\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 64\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Taper\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: H1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.6875 inches (1-11\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 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\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.01 pounds\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: 1000300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743874613554,"sku":"1000300","price":34.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/326d7ab8b02d8071a42bd324ef4f1ff7_7e8a91d4-1190-4654-94f2-69d96c0da88a.jpg?v=1788850656","url":"https:\/\/voomisupply.com\/products\/osg-1000300-straight-flute-tap-1-64-unc-taper-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
