Built from high-speed steel with a titanium carbonitride (TiCN) coating, this tap delivers improved wear resistance and reduced friction compared to uncoated HSS tooling. It features a plug chamfer for through-hole applications and a 2-flute spiral point geometry that pushes chips forward, ahead of the cutting zone, reducing clogging during tapping. The overall length is 1.625 inches with a thread length of 0.3125 inches (5\/16 inches) and a shank diameter of 0.141 inches. The H2 thread limit provides consistent fit within the 2B class-of-fit tolerance standard. Machinists and tool-and-die tradespeople rely on this tap for precision small-diameter threading work.\u003c\/p\u003e\u003cp\u003eThis tap is suited for through-hole tapping operations in materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. Its TiCN coating makes it particularly effective in harder ferrous materials where tool life matters. The right-hand thread direction is standard for conventional fastener applications. At a 0-80 UNF size, it is commonly used in instrument manufacturing, electronics assembly, optics, and other precision fabrication environments where fine-thread fasteners are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0-80 UNF thread form with right-hand thread direction and 2B class of fit\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and extends tool life versus bare HSS\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips ahead of the tap, reducing chip-related breakage in through-hole applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer suits general-purpose through-hole threading applications\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for consistent 2B tolerance compliance\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup for bench and machine use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in through-hole tapping operations requiring a 0-80 UNF thread in the material types listed by the manufacturer: aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap should be installed in a tap holder or tapping head appropriate for the 0.141-inch shank diameter. Always ensure the workpiece is securely fixtured and the spindle or driver is properly aligned to the pre-drilled pilot hole before engaging the tap. Reverse the tap periodically when hand-tapping brittle materials to break and clear chips. At a 0-80 size, these taps are highly susceptible to breakage from misalignment or excessive feed force — use a tapping fluid or cutting oil appropriate for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 0-80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.35 inches (5\/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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.009 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 105\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: 1205008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731978977586,"sku":"1205008","price":50.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/427487892d1da75241b2f33fab615c6f.jpg?v=1788737540","url":"https:\/\/voomisupply.com\/products\/osg-1205008-spiral-point-tap-0-80-unf-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
