It cuts a 0-80 UNF thread profile using a 2-flute, plug chamfer geometry that pushes chips forward ahead of the cutting zone, keeping the flutes clear during operation. The tap is manufactured from high speed steel and coated with titanium nitride (TiN) for improved surface hardness and wear resistance. It carries an H2 thread limit and a Class 2B fit tolerance, making it suitable for standard fastener thread requirements. Licensed machinists, tool-and-die workers, and maintenance technicians are the typical users for this size range.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading operations in small-diameter fastener applications. The 0-80 thread size is among the finest commercially standard UNF pitches and is commonly encountered in instrument work, electronics enclosures, optical assemblies, and precision mechanical subassemblies. Suitable material applications include alloy steel, carbon steel, and aluminum. The spiral point geometry makes it particularly effective in through-holes where chips can exit freely in front of the tap rather than packing behind it.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0-80 UNF thread form with Class 2B fit and H2 thread limit for standard tolerance threading\u003c\/li\u003e\n  \u003cli\u003eSpiral point (gun tap) geometry pushes chips forward, reducing clogging in through-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life compared to uncoated HSS\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) eases entry and is suitable for most standard through-hole jobs\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement, compatible with conventional tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, carbon steel, and aluminum workpieces requiring a 0-80 UNF Class 2B thread.

Always ensure the workpiece is securely fixtured and the tap is started perpendicular to the hole to avoid thread runout or breakage at this small diameter. Apply appropriate tapping fluid for the workpiece material before and during the operation. Due to the small shank diameter, use controlled feed pressure to minimize the risk of tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eThreads per Inch\u003c\/strong\u003e: 80\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: Plug\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.688 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.310 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 Size\u003c\/strong\u003e: 2.79 mm\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: 1011TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C55290\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51712521896242,"sku":"C55290","price":48.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d273f18fd6075156661c966c4a2eab66.jpg?v=1788486421","url":"https:\/\/voomisupply.com\/products\/cleveland-c55290-spiral-point-tap-0-80-unf-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
