Built from high speed steel with a titanium nitride (TiN) coating, it offers extended wear resistance and reduced friction during threading operations. The plug chamfer style provides a balanced lead-in suited for both through-hole and blind-hole applications. With 3 flutes, an H3 thread limit, and a Class 2B fit tolerance, this tap produces consistent, reliable threads in production and maintenance machining environments. It is installed by machinists, tool-and-die workers, and maintenance mechanics working with a hand tap wrench or tapping fixture.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in cast iron, stainless steel, and steel workpieces. The plug chamfer makes it appropriate as a general-purpose starting tap where chamfer length is not critical. Its straight-flute geometry works in both through-hole and blind-hole scenarios where chip clearance is manageable. The right-hand thread direction matches the vast majority of standard fastener applications. It is a single-piece unit packaged individually and is part of the Cleveland Series 1002TN product line.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh speed steel construction with TiN coating for extended tool life and reduced cutting friction\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3-flute straight-flute geometry for versatile through-hole and blind-hole threading\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit with Class 2B fit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 3\/8-16 UNC thread form for common fastener compatibility\u003c\/li\u003e\n  \u003cli\u003eNo coolant-through requirement — compatible with standard hand-tapping and machine-tapping setups\u003c\/li\u003e\n  \u003cli\u003eSeries 1002TN — part of a consistent Cleveland tap family for toolroom and production use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct toolroom-stock tap for 3\/8-16 UNC internal threading applications in cast iron, stainless steel, and steel.

Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before beginning. Apply appropriate cutting fluid for the workpiece material — especially when threading stainless steel — to reduce heat buildup and tool wear. Back the tap out periodically to clear chips and prevent tap breakage in blind-hole applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\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: 16\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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches (2-15\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.75 inches (3\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.381 inches (9.68 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Drive Size\u003c\/strong\u003e: 0.286 inches (7.26 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Drive Length\u003c\/strong\u003e: 0.4375 inches (7\/16 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\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\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: 1.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C55180\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690684186930,"sku":"C55180","price":45.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13871369d7a656469a00992907e8f551.jpg?v=1788273922","url":"https:\/\/voomisupply.com\/products\/cleveland-c55180-hand-tap-3-8-16-unc-plug-rh-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
