Designed for cutting internal threads in both blind and through holes, this tap delivers consistent thread quality in a range of common ferrous and non-ferrous workpiece materials. The 4-flute straight flute geometry provides good chip clearance and cutting stability. With an overall length of 5.125 inches and a thread length of 2.5 inches, the C55152 is sized for production and maintenance threading operations where a standard right-hand UNC tap is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for manual threading operations performed by machinists, tool and die makers, maintenance mechanics, and MRO professionals. The plug chamfer makes it the standard choice when starting a tap in a hole that has a slight lead-in, handling the bulk of threading work in both blind hole and through-hole applications. The H4 thread limit and 3B class of fit specify a tolerance range appropriate for standard mechanical assembly fits in steel, aluminum, and similar materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread form with right-hand direction and 3B class of fit\u003c\/li\u003e\n  \u003cli\u003eH4 thread limit for controlled tolerance in standard mechanical fits\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and lubricity, extending tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute design suitable for blind hole and through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides toughness for hand tapping and low-speed machine tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 threads) for easy hole entry and efficient thread cutting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in alloy steel, aluminum, carbon steel, and free-machining stainless steel.

Ensure the workpiece is securely fixtured before starting the thread. Apply appropriate cutting fluid for the workpiece material to reduce friction and heat buildup. Back the tap off a quarter turn periodically to break chips and prevent tap breakage, particularly in blind holes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\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: 8\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\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.8000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.6000 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\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1002TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: C55152\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699786875186,"sku":"C55152","price":222.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a046860dc19b0d12280e378f250db8f1.jpg?v=1788380944","url":"https:\/\/voomisupply.com\/products\/cleveland-c55152-hand-tap-1-8-unc-plug-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
