Built from vanadium high-speed steel with a steam oxide coating, this tap handles stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel. The 45-degree helix angle and 3-flute spiral design evacuate chips back away from the cutting zone, making it well-suited for blind-hole tapping where chip clearance is critical. At 2 inches overall length with an 11\/16-inch thread length, it fits standard tap handles and CNC toolholders for the 6-32 size range.\u003c\/p\u003e\u003cp\u003eThis bottoming tap is intended for finishing threads to the bottom of a blind hole where a plug or taper tap has already started the thread. It carries a 2B class of fit and H5 thread limit, suitable for general-purpose threaded assemblies requiring standard tolerance. Typical applications include threading small fastener holes in sheet metal, machined components, and structural assemblies across manufacturing, maintenance, and repair operations. It is used by machinists, tool-and-die makers, and maintenance technicians working with hand tap handles or machine tapping setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer configuration for threading to the bottom of blind holes\u003c\/li\u003e\n\u003cli\u003e45-degree right-hand spiral flute geometry for efficient chip evacuation in blind-hole applications\u003c\/li\u003e\n\u003cli\u003eVanadium high-speed steel construction for improved wear resistance and toughness\u003c\/li\u003e\n\u003cli\u003eSteam oxide coating reduces friction and provides moderate corrosion resistance during cutting\u003c\/li\u003e\n\u003cli\u003eH5 thread limit and 2B class of fit for standard general-purpose thread tolerances\u003c\/li\u003e\n\u003cli\u003eCompatible with stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 6-32 UNC 2B right-hand internal threads in stainless steel, high-carbon steel, low-carbon steel, and medium-carbon steel.

Ensure the workpiece is securely fixtured and that a proper tapping fluid or cutting oil compatible with the workpiece material is applied before and during the operation. For blind holes, use a taper or plug tap to start the thread before advancing with this bottoming tap. Inspect the tap for chipping or wear before each use, as a damaged tap can produce out-of-tolerance threads or break off in the hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 6-32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 32\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.248 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\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\u003c\/strong\u003e: Steam Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 303\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 1746801\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51735263871282,"sku":"1746801","price":49.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c416657469847242609824372b649255.jpg?v=1788771173","url":"https:\/\/voomisupply.com\/products\/osg-1746801-spiral-flute-tap-6-32-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
