It features two flutes ground from high-speed steel (HSS) with a bright, uncoated finish. The plug chamfer provides a gradual entry into the workpiece, making it well suited for through-hole tapping applications. With an overall length of 1-9\/16 inches and a thread length of 1\/4 inch, this is a compact, precision tap built for small-diameter threading work. A licensed machinist or tooling technician is the typical installer in a machine shop or production floor setting.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for threading small-diameter through holes in a range of ferrous and non-ferrous materials, including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel. Its H1 thread limit makes it appropriate for close-tolerance work where minimal oversize is required. The straight flute design suits applications where chips can be pushed ahead or where workpiece material is relatively free-cutting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eThread size 00-90 UNC with a right-hand thread direction\u003c\/li\u003e\n  \u003cli\u003eTwo-flute straight flute geometry for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for gradual thread engagement on entry\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides good wear resistance across multiple materials\u003c\/li\u003e\n  \u003cli\u003eH1 thread limit for close-tolerance, minimal-oversize applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish suitable for use with cutting fluid in general machining\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through feature; external lubrication is required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 00-90 UNC through holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces.

Ensure the workpiece is properly secured and the tap is aligned square to the hole before engagement. Apply an appropriate cutting fluid or tapping compound for the workpiece material before and during threading. Never reverse a tap under load without first relieving chip pressure, as breakage risk is high at this small diameter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 00-90\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: 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\u003eThread Limit\u003c\/strong\u003e: H1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 90\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.2795 inches (1\/4 inches nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.7283 inches (1-9\/16 inches nominal)\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\u003eNeck Length\u003c\/strong\u003e: 0.3386 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\u003eSeries\u003c\/strong\u003e: S110\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel\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: 1030000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743168299314,"sku":"1030000","price":67.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a01123ff55c998cd97ff36d8598837d.jpg?v=1788843465","url":"https:\/\/voomisupply.com\/products\/osg-1030000-straight-flute-tap-00-90-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
