Built from Vanadium High Speed Steel (HSS-E) and finished with a Titanium Carbonitride (TiCN) coating, this tap delivers improved wear resistance and surface hardness compared to uncoated tooling. The 3-flute spiral point geometry pushes chips forward ahead of the cut, making it well-suited for threading through-holes without chip packing. Overall length is 3.157 inches with a thread length of 0.858 inches and a shank diameter of 0.323 inches. Thread limit is H3, indicating a standard tolerance class for general-purpose threading applications.\u003c\/p\u003e\u003cp\u003eThis tap is intended for use in through-hole threading operations across production and maintenance machining environments. Suitable material applications include aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. The plug chamfer provides a gradual lead-in over several threads, making it appropriate for starting threads in through-holes or where a bottoming tap is not required. It is used by machinists, tool and die makers, and maintenance technicians working with manual or CNC tapping equipment. Coolant-through capability is not included on this tap.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-20 UNF thread form with right-hand thread direction\u003c\/li\u003e\n\u003cli\u003e3-flute spiral point geometry pushes chips forward for clean through-hole threading\u003c\/li\u003e\n\u003cli\u003eTiCN coating increases surface hardness and extends tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eVanadium High Speed Steel (HSS-E) construction for toughness in interrupted and varied materials\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for gradual thread lead-in in through-hole applications\u003c\/li\u003e\n\u003cli\u003eH3 thread limit for standard general-purpose tolerance class\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole tapping of 7\/16-20 UNF threads in aluminum, stainless steel, carbon steels, alloy steel, die steel, and cast iron workpieces.

Ensure the workpiece is securely fixtured and the tap is properly aligned to avoid tap breakage or cross-threading. Apply appropriate cutting fluid for the material being tapped; HSS-E taps benefit from sulfo-chlorinated cutting oil in ferrous materials and water-soluble coolant in aluminum. Always back the tap out periodically to clear chips when operating near the bottom of a through-hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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 Limit\u003c\/strong\u003e: H3\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\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\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\u003eOversize\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\u003eSeries\u003c\/strong\u003e: 280\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.085 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: 2832208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51754356736306,"sku":"2832208","price":64.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f037cfbe3d1872fe259a871295acd92f_2ffaffaa-5ae7-4f19-9331-635415b60a7c.jpg?v=1788944646","url":"https:\/\/voomisupply.com\/products\/osg-2832208-spiral-point-tap-7-16-20-unf-ticn-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
