Built from vanadium high-speed steel (HSS-E) with a steam oxide coating, it drives chips forward ahead of the cutting edge, making it well suited for through-hole tapping operations. The plug chamfer eases entry and distributes cutting load across the first few threads. Thread limit is H3, providing the tolerance class most commonly specified for standard unified coarse thread fits. Overall length is 3.157 inches with a thread length of 0.858 inches and a shank diameter of 0.323 inches.\u003c\/p\u003e\u003cp\u003eThis tap is used in production and maintenance machining environments where through-hole tapping in steel, cast iron, aluminum, and similar materials is required. Typical applications include fabrication shops, tool rooms, and field maintenance operations. The right-hand cut and standard UNC thread form make it a direct fit for the most common fastener thread specifications encountered in industrial and mechanical assembly work. It is suitable for use in hand tapping, drill press, and CNC tapping operations without coolant-through requirements.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward, reducing chip jamming in through-hole applications\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel (HSS-E) construction provides increased wear resistance over standard HSS\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and improves lubrication retention during tapping\u003c\/li\u003e\n\u003cli\u003eH3 thread limit suits standard tolerance fits for 7\/16-14 UNC fasteners\u003c\/li\u003e\n\u003cli\u003ePlug chamfer with 3 flutes balances cutting speed and tool strength\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies setup in standard shop environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping in aluminum, hardened steel, stainless steel, high-carbon steel, low-carbon steel, medium-carbon steel, alloy steel, die steel, and cast iron.

Ensure the workpiece is securely fixtured and that the correct tap drill size for 7\/16-14 UNC is used prior to tapping. Apply appropriate cutting fluid to reduce heat and extend tool life. Do not force the tap if resistance increases suddenly, as this may indicate chip packing or workpiece hardness beyond the tool rating.\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\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: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.858 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterrupted Thread\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 280\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: 2832001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51730398773554,"sku":"2832001","price":51.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8ce97f9cbb28701b16385db1fb94e688.jpg?v=1788716767","url":"https:\/\/voomisupply.com\/products\/osg-2832001-spiral-point-tap-7-16-14-unc-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
