It cuts a 4-40 UNF thread profile with a 2-flute, right-hand spiral point geometry that pushes chips forward ahead of the cutting zone, reducing the risk of chip packing in blind-adjacent through-hole applications. The tap is manufactured from High Speed Steel with a TiCN (Titanium Carbonitride) coating, which improves surface hardness and lubricity for extended tool life. The H2 thread limit holds close dimensional tolerances for a Class 2B fit. Overall length is 1.875 inches with a 0.3100-inch thread length.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 4-40 UNF holes in cast iron, stainless steel, and carbon steel workpieces. It is a practical choice for machine shops, maintenance technicians, and field service professionals working with small-diameter fastener holes in industrial equipment, electrical enclosures, and instrumentation assemblies. The plug chamfer style makes it appropriate for through-hole applications where the tap can pass fully through the material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-40 UNF thread profile with 40 threads per inch\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n\u003cli\u003eH2 thread limit for Class 2B fit tolerance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, plug chamfer style\u003c\/li\u003e\n\u003cli\u003eRated for use in cast iron, stainless steel, and steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading in cast iron, stainless steel, and steel.

Secure the workpiece before tapping and ensure the pilot hole diameter is correct for a 4-40 thread before starting. Apply appropriate cutting fluid for the material being threaded, particularly when working in stainless steel. Coolant-through operation is not supported on this tap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 4-40\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: 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 Style\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: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.3100 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1410 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.2600 inches\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: 1011TICN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C55374\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51708263530802,"sku":"C55374","price":36.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1203c7854de6d4d70acfe82a7e73aef6_377fc14e-f344-4d01-aeb2-d1b7c14e7f05.jpg?v=1788445152","url":"https:\/\/voomisupply.com\/products\/cleveland-c55374-spiral-point-tap-4-40-unf-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
