Built from high-speed steel with a bright, uncoated finish, it is suited for production and maintenance threading operations in machine shop and fabrication environments. The plug chamfer geometry drives chips forward ahead of the tap as it advances through the hole, making it well matched to through-hole applications. With an H3 thread limit and a 3B class of fit, the C57215 holds consistent tolerance for general-purpose threaded fastener assemblies. Licensed machinists, tool and die makers, and maintenance mechanics are the primary users of this tap.\u003c\/p\u003e\n\u003cp\u003eThe C57215 is appropriate for threading alloy steel, carbon steel, and aluminum workpieces. Its through-hole threading application makes it a standard choice on CNC machining centers, knee mills, and drill press setups where a through-hole is pre-drilled to the correct tap drill diameter before the tapping cycle. The plug chamfer provides a gradual cutting action that distributes load across the leading threads, reducing tool deflection at typical feed rates for this diameter and pitch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with H3 thread limit for consistent 3B class of fit tolerances\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer advances chips forward, optimized for through-hole threading operations\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides hardness and toughness across alloy steel, carbon steel, and aluminum\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish allows for easy visual wear inspection during use\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction compatible with standard tapping heads and CNC canned tapping cycles\u003c\/li\u003e\n  \u003cli\u003e3-flute design balances chip clearance and cutting-edge support at this thread size\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading applications in alloy steel, carbon steel, and aluminum workpieces requiring a 1\/2-13 UNC thread form and a 3B class of fit.

Power down all machine spindles and lock out energy sources before changing tooling. Apply an appropriate cutting fluid or tapping compound for the workpiece material to extend tool life and maintain thread quality. Do not reverse the tap under power without a reversing-capable tapping attachment or a synchronized CNC tapping cycle.\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\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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: Bright\/Uncoated\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: 0.940 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.730 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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon 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: 1011\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.108 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: C57215\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722392109362,"sku":"C57215","price":42.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63029b2bfb4bcf1c17eb1f8af1e91546.jpg?v=1788590422","url":"https:\/\/voomisupply.com\/products\/cleveland-c57215-spiral-point-tap-1-2-13-unc-plug-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
