Built from vanadium high-speed steel and finished with a steam oxide coating, this tap delivers improved lubricity and corrosion resistance during cutting operations. At 6 inches overall length, it reaches into deep or recessed workpiece features where standard-length taps cannot. The H3 thread limit provides the tolerance consistency required for 3B class of fit threads. Three flutes with a spiral point design push chips forward ahead of the cutting action, keeping the flutes clear during machine tapping.\u003c\/p\u003e\u003cp\u003eThis extension tap is suited for production and maintenance machining environments where through-hole threading is performed on carbon steel, hardened steel, and stainless steel workpieces. The reduced shank and extended neck allow access in fixtures or bored features with limited clearance. Typical users include machinists, tool and die makers, and maintenance professionals working on manual mills, CNC machining centers, or drill presses equipped with tapping attachments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point plug chamfer pushes chips forward, ideal for through-hole threading\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel construction for durability in steel and stainless steel applications\u003c\/li\u003e\n\u003cli\u003eSteam oxide finish improves lubricity and reduces galling during the tapping process\u003c\/li\u003e\n\u003cli\u003eH3 thread limit ensures consistent 3B class of fit tolerance across production runs\u003c\/li\u003e\n\u003cli\u003eReduced shank with extended neck reaches deep or obstructed hole locations\u003c\/li\u003e\n\u003cli\u003eRight-hand flute and thread direction for standard machine tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for threading 5\/8-11 UNC right-hand through holes in carbon steel, hardened steel, and stainless steel workpieces.

Ensure the workpiece is securely fixtured and the spindle is properly aligned before beginning the tapping cycle. Use an appropriate cutting fluid for the workpiece material to extend tap life and maintain thread quality. Inspect the tap for wear or chipping before each use and replace when cutting performance degrades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.562 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.48 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Shank\u003c\/strong\u003e: Yes\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: Carbon Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 397\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 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: 1765601\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728767418674,"sku":"1765601","price":126.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3ab9dfc3e80b742c9f4a062fe4da599d.jpg?v=1788696014","url":"https:\/\/voomisupply.com\/products\/osg-1765601-extension-tap-5-8-11-spiral-point-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
