Sized at 1\/2-13 UNC with a 2B class of fit, it produces threads to H5 tolerance in a wide range of ferrous and non-ferrous materials. The 50-degree helix angle drives chips up and out of the hole, making this tap well-suited for blind-hole applications where chip evacuation is critical. Manufactured from high-speed steel with a bright uncoated finish, it is installed by machinists and tool-and-die trades using standard tapping equipment or CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis tap is suited for production and job-shop environments where clean, accurate 1\/2-13 UNC threads are required in blind holes. The bottoming chamfer allows threading close to the bottom of a blind hole, maximizing usable thread depth. Compatible materials include aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel, covering a broad range of common workpiece materials found in general machining, maintenance, and fabrication work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for maximum thread depth in blind holes\u003c\/li\u003e\n\u003cli\u003e50-degree right-hand spiral flute for efficient upward chip evacuation\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and 2B class of fit for consistent, accurate thread geometry\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction provides durability across a range of ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for use with cutting fluids and tapping compounds\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup on standard tapping equipment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, and high-carbon steel workpieces requiring 1\/2-13 UNC right-hand threads to a 2B class of fit.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is installed by machinists using a tap wrench, tapping stand, or CNC machining center with appropriate speed and feed settings for the workpiece material. Ensure the correct drill size for a 1\/2-13 UNC thread is used before tapping and that the hole is properly chamfered to guide tap entry. Apply a suitable cutting fluid or tapping compound to extend tool life and improve thread finish. Never reverse a tap under load without relieving cutting pressure first, as this may cause breakage in the hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\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: 0.96 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.929 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 Length\u003c\/strong\u003e: 0.4375 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\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.105 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5007100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51742646305074,"sku":"5007100","price":99.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b6113df7ea01a9325be29a684511e41.jpg?v=1788838570","url":"https:\/\/voomisupply.com\/products\/osg-5007100-spiral-flute-tap-1-2-13-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
