Manufactured from high speed steel (HSS) with a bright, uncoated finish, this tap produces 1\/2-13 UNC right-hand threads to a Class 3B fit with an H3 thread limit. The plug chamfer — with a moderate lead-in of several threads — makes it well suited for starting in a pre-drilled hole while maintaining control through the threading pass. Overall length is 3.375 inches with a thread length of 0.94 inches. Machinists, toolroom technicians, and maintenance mechanics reach for this tap when accuracy and thread quality matter.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in general metalworking, maintenance, repair, and production threading applications where 1\/2-13 UNC internal threads are required. It is appropriate for use in alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces. The straight-flute geometry is particularly effective in through-hole applications and in short blind holes where chip clearance is managed manually or with cutting fluid. It fits standard tap wrenches sized for a 0.275-inch square drive.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form, right-hand, Class 3B fit with H3 thread limit for precise tolerance control\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides a balanced lead-in suitable for both blind-hole and through-hole threading\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers good wear resistance across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish allows direct visual inspection of the cutting edges before and after use\u003c\/li\u003e\n  \u003cli\u003e3-flute straight-flute design works with standard tap wrenches and T-handles\u003c\/li\u003e\n  \u003cli\u003eCompatible with alloy steel, carbon steel, aluminum, and free-machining stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1\/2-13 UNC Class 3B internal thread.

Before tapping, verify the pilot hole diameter is correct for 1\/2-13 UNC to avoid tap breakage or undersized threads. Apply a suitable cutting fluid for the workpiece material to extend tap life and improve thread finish. Back the tap off periodically during cutting to break chips and prevent binding, especially 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: 1\/2-13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 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: Bright\/Uncoated\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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\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: 1002\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: C54729\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715210969394,"sku":"C54729","price":51.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0e88a0e6f52985c32b7230b4faa4bd7.jpg?v=1788510639","url":"https:\/\/voomisupply.com\/products\/cleveland-c54729-hand-tap-1-2-13-unc-plug-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
