Built from vanadium high-speed steel and finished with a steam oxide coating, this tap offers solid wear resistance and chip evacuation suited to production and maintenance threading work. The 45-degree helix angle drives chips up and out of the hole, making it a practical choice for blind-hole applications where chip packing is a concern. The modified bottoming chamfer allows threading closer to the bottom of a blind hole than a standard plug or taper tap. Licensed machinists, tool-and-die makers, and maintenance mechanics are the typical users.\u003c\/p\u003e\u003cp\u003eThis tap is intended for threading stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel. The modified bottoming chamfer and spiral flute geometry make it well-suited for blind-hole work in precision machining environments and general metal fabrication. With an overall length of 3.156 inches and a thread length of 0.571 inches, it fits standard tap holders and machine spindles sized for this shank diameter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-14 UNC thread form, right-hand direction, H5 thread limit for consistent fit tolerances\u003c\/li\u003e\n\u003cli\u003e45-degree right-hand spiral flute for efficient upward chip evacuation in blind holes\u003c\/li\u003e\n\u003cli\u003eModified bottoming chamfer allows threading close to the bottom of a blind hole\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel construction for durability in ferrous materials\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and provides light corrosion resistance\u003c\/li\u003e\n\u003cli\u003eOSG Series 303 design for repeatable performance in production environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel.

Power down or disable the spindle before loading or removing the tap. Use appropriate cutting fluid for the workpiece material, particularly when threading stainless steel, to reduce heat buildup and extend tap life. Do not exceed the recommended feed rate for the helix angle and material combination, and never reverse a tap under power without confirming the machine is programmed for reverse-feed extraction.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-14 UNC\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: 14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.571 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.713 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.242 inches\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: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.077 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: 1723201\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741707469106,"sku":"1723201","price":72.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0943df97fb123482a4194a6e467c2f87_390401ec-c7c2-404f-aaa9-4bdaabe05617.jpg?v=1788833037","url":"https:\/\/voomisupply.com\/products\/osg-1723201-spiral-flute-tap-7-16-14-unc-modified-bottoming","provider":"Voomi Supply","version":"1.0","type":"link"}
