It cuts a 5-40 UNC thread using a 2-flute, plug chamfer geometry that pushes chips forward ahead of the cutting zone, keeping flutes clear during production tapping. The tap is manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating that increases surface hardness and extends tool life in abrasive materials. It carries an H2 thread limit and fits Class 2B\/3B tolerance applications. Overall length is 1.938 inches with a thread length of 0.310 inches. Right-hand cut only.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole applications in alloy steel, carbon steel, and aluminum. The plug chamfer distributes cutting load across the first several threads, making it a practical choice for machine tapping in CNC machining centers, drill presses, and tapping heads. The 5-40 UNC thread is common in small fastener applications found in electronics enclosures, instrument panels, and light mechanical assemblies. The TiN finish is particularly beneficial when running higher spindle speeds or tapping harder steels where uncoated HSS would wear prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point (gun tap) geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n  \u003cli\u003eTiN coating improves wear resistance and reduces friction at the cutting edge\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction handles alloy steel, carbon steel, and aluminum\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load for smooth machine tapping entry\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit holds tight tolerances for Class 2B\/3B fits\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, and carbon steel workpieces requiring a 5-40 UNC thread form with a Class 2B or 3B fit.

Secure the tap in a floating tap holder or rigid tapping chuck sized for the shank diameter before use. Ensure the workpiece is clamped securely and the pilot hole is drilled to the correct tap drill size for a 5-40 UNC thread before engaging the tap. Apply appropriate cutting fluid for the workpiece material to maximize tool life and thread quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40\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: 40\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\/3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: 1.938 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\u003eNeck Length\u003c\/strong\u003e: 0.330 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1011TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: C55298\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51693154369842,"sku":"C55298","price":29.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51cfc4fc6106b65c62f4a15bae9efb9e.jpg?v=1788308101","url":"https:\/\/voomisupply.com\/products\/cleveland-c55298-spiral-point-tap-5-40-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
