Built from 3% vanadium high-speed steel (HSS-E) with a steam oxide finish, this tap delivers improved lubricity and wear resistance compared to uncoated HSS tooling. The spiral point geometry pushes chips ahead of the cut rather than packing them into the flute, making it well suited for through-hole tapping operations. With 3 flutes, an H7 thread limit, and right-hand thread direction, the 2842101 is a production-grade tap appropriate for machine or hand tapping where consistent thread quality is required.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machine shops, maintenance and repair environments, and manufacturing cells where 7\/16-14 UNC internal threads are produced in through-hole applications. The steam oxide coating reduces friction and helps resist built-up edge when cutting aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, and cast iron. The plug chamfer style provides a gradual lead-in over several threads, balancing cutting force across the tap entry. It is suitable for CNC tapping centers, drill press setups, and manual tapping operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward through the hole, reducing chip packing in through-hole tapping\u003c\/li\u003e\n  \u003cli\u003e3% vanadium high-speed steel (HSS-E) construction for increased toughness and wear resistance over standard M2 HSS\u003c\/li\u003e\n  \u003cli\u003eSteam oxide coating improves lubricity and reduces galling, particularly in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eH7 thread limit (oversize) accommodates standard tap tolerances for 7\/16-14 UNC threads\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer distributes cutting load across multiple leading threads for smooth entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 3-flute design compatible with standard tapping chucks and holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole tapping of 7\/16-14 UNC threads in aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, hardened steel, and cast iron.

Always ensure the workpiece is securely fixtured and that the tap is aligned perpendicular to the hole centerline before beginning the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Never reverse a tap under power without confirming the machine is set for reverse-thread extraction.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 Style\u003c\/strong\u003e: Plug\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: H7 (Oversize)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Vanadium High-Speed Steel (HSS-E, 3% Vanadium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Steam Oxide\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 (1-7\/16 inches nominal)\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\u003eSeries\u003c\/strong\u003e: 280\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2842101\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743661392178,"sku":"2842101","price":51.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f037cfbe3d1872fe259a871295acd92f_bcc8f6cb-f208-4c50-8adc-b194e1de11c6.jpg?v=1788849107","url":"https:\/\/voomisupply.com\/products\/osg-2842101-spiral-point-tap-7-16-14-unc-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
