It produces a 1\/2-13 UNC thread form with a plug chamfer and a 3B class of fit, meeting standard dimensional tolerance requirements for general mechanical assemblies. Built from powdered metal high-speed steel (PM HSS) and coated with titanium carbonitride (TiCN), the tap delivers improved wear resistance and heat tolerance compared to conventional HSS tooling. Machinists, tool and die makers, and production operators use this tap on CNC machining centers, knee mills, and drill presses for ferrous and non-ferrous workpieces.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production tapping in steel, cast iron, aluminum, and similar materials where a through-hole threading operation is required. The plug chamfer style distributes cutting load across several leading threads, making it appropriate for material thicknesses greater than 1.5 times the thread diameter. The 4-flute spiral point geometry pushes chips forward ahead of the tap, making it particularly effective in through-hole applications where chip evacuation from the back of the hole is not a concern. It is not recommended for blind-hole applications where chip clearance is restricted.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/2-13 UNC thread form with right-hand thread direction for standard fastener compatibility\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting force across multiple lead threads for reduced torque and longer tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral point geometry pushes chips forward, optimizing performance in through-hole operations\u003c\/li\u003e\n  \u003cli\u003ePowdered metal HSS construction provides higher hardness and wear resistance than conventional HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction at the cutting edge and extends service intervals in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit ensures accurate fit tolerance within the 3B class of fit specification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use threading tool compatible with standard 1\/2-13 UNC through-hole tapping applications on manual and CNC machine tools equipped with a tap holder or floating tap chuck sized for this shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use should be performed by a qualified machinist following standard tapping procedures. Always secure the workpiece firmly before beginning the tapping operation and use a compatible tap holder or floating chuck to minimize axial misalignment. Apply an appropriate cutting fluid or tapping compound for the workpiece material to reduce heat buildup and extend tap life. Inspect the tap for chipping or wear before each use and replace if cutting edges show signs of deterioration to avoid thread damage or tap breakage.\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\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\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal HSS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOversize\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: ACCUPRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 30163-00C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732032553266,"sku":"30163-00C","price":87.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41937a84d2086ebbe35a71b92e25bd31.jpg?v=1788738432","url":"https:\/\/voomisupply.com\/products\/accupro-30163-00c-spiral-point-tap-1-2-13-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
