Built from vanadium high-speed steel and finished with a titanium carbonitride (TiCN) coating, it delivers improved wear resistance and lubricity compared to uncoated HSS taps. The modified bottoming chamfer allows threading close to the bottom of blind holes, making it a practical choice when full thread depth is required near the base of a hole. With a 45-degree helix angle and right-hand spiral flute design, chips are pulled up and out of the hole during the tapping operation, reducing the risk of packing and tap breakage. The 3B class of fit produces threads within standard tolerance for most commercial and precision fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for production and maintenance tapping operations on alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel workpieces. It fits into standard tap holders and is compatible with both CNC machining centers and manual tapping setups. The 6-32 UNC thread size is common in light mechanical assemblies, electronics enclosures, and instrument panels. Machinists, tool-and-die makers, and maintenance technicians will find this tap appropriate for through-hole and blind-hole applications where spiral flute chip evacuation is preferred over straight flute designs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVanadium high-speed steel construction for increased toughness and wear resistance in hard ferrous materials\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life compared to uncoated or TiN-coated taps\u003c\/li\u003e\n  \u003cli\u003e45-degree right-hand spiral flute geometry pulls chips up and out of blind holes during cutting\u003c\/li\u003e\n  \u003cli\u003eModified bottoming chamfer enables threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit and 3B class of fit for standard commercial thread tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for tapping 6-32 UNC threads in alloy steel, carbon steel, cast iron, stainless steel, die steel, and hardened steel.

Power down all equipment before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tap life and maintain thread quality. Verify the correct spindle direction and feed rate for the thread pitch before initiating the tapping cycle to prevent tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Modified Bottoming\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: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.156 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 Diameter\u003c\/strong\u003e: 0.323 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.712 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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 290\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: 2907408\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51741096345906,"sku":"2907408","price":49.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0755543a9ef1e6e0faae58f53d8df321.jpg?v=1788829355","url":"https:\/\/voomisupply.com\/products\/osg-2907408-spiral-flute-tap-6-32-unc-ticn-vanadium-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
