The spiral point geometry pushes chips forward ahead of the cutting zone, keeping the flutes clear and reducing the risk of chip packing in through-hole applications. Built from high-speed steel with an elektraLUBE dry-film coating, this tap delivers consistent thread quality across production runs without requiring flood coolant. It carries a plug chamfer with a 3B class of fit and H3 thread limit, making it a standard choice for precision threaded assemblies in machining, maintenance, and repair work.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations in a shop or field machining context. The 1\/2-20 UNF thread form is common in automotive, aerospace, and general mechanical assembly applications. It is compatible with materials including aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel. Machinists and tool-and-die technicians will find the H3 oversize limit and 3B fit appropriate for standard tolerance threaded holes requiring reliable engagement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point design pushes chips forward, ideal for through-hole tapping\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction for durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eelektraLUBE dry-film coating reduces friction and extends tool life without wet coolant\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer provides progressive cutting entry and good thread lead-in\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 3B class of fit meet standard precision requirements for threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, compatible with standard tapping heads and CNC toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading 1\/2-20 UNF through-holes in aluminum, cast aluminum, cast iron, low-carbon steel, medium-carbon steel, high-carbon steel, and hardened steel workpieces.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter before tapping. Apply cutting oil or a compatible tapping fluid at the entry point even with the dry-film coating present, particularly in harder steels. Do not reverse-feed to break chips with this tap in blind holes, as the spiral point is intended for through-hole use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\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\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1-21\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: elektraLUBE\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\u003eSeries\u003c\/strong\u003e: 105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, Low-Carbon Steel, Medium-Carbon Steel, High-Carbon Steel, Hardened Steel\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: 1232602\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51737399787826,"sku":"1232602","price":57.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f815ce4ecd3870598f5eacb1c01bbe4.jpg?v=1788788049","url":"https:\/\/voomisupply.com\/products\/osg-1232602-spiral-point-tap-1-2-20-unf-hss-elektralube","provider":"Voomi Supply","version":"1.0","type":"link"}
