It features a plug chamfer, 3-flute geometry, and a titanium nitride (TiN) coating over a vanadium high-speed steel (HSS-E) body. The spiral point design pushes chips forward ahead of the cut, making it well suited for through-hole applications where chip evacuation is critical. At 3.15 inches overall length with a 0.598-inch thread length, it fits standard tap holders and CNC tooling setups. Right-hand thread direction. Coolant-through capability supports higher feed rates and extended tool life in production environments.\u003c\/p\u003e\u003cp\u003eThis tap is appropriate for threading operations in both manual and CNC machining applications. Suitable material applications include aluminum, low-carbon steel, medium-carbon steel, high-carbon steel, alloy steel, die steel, stainless steel, and cast iron. The TiN coating reduces friction and improves wear resistance, which is particularly beneficial when running production volumes or working with abrasive materials. The 2B class of fit meets standard UNC fastener tolerances for general mechanical assembly. Machinists, tool-and-die makers, and CNC operators in manufacturing and maintenance environments are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point geometry pushes chips forward for clean through-hole tapping\u003c\/li\u003e\n\u003cli\u003eTiN coating reduces friction and extends tool life across abrasive materials\u003c\/li\u003e\n\u003cli\u003eVanadium HSS-E body provides toughness and heat resistance\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports high-feed production tapping\u003c\/li\u003e\n\u003cli\u003e2B class of fit meets standard UNC assembly tolerances\u003c\/li\u003e\n\u003cli\u003eRight-hand thread, non-oversize, non-interrupted thread configuration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard tap holders and CNC toolholding systems accepting a 0.255-inch shank diameter.

Ensure the workpiece is securely fixtured and the spindle speed and feed rate are set per the tool manufacturer's recommendations for the material being tapped. Use appropriate cutting fluid or coolant to optimize performance and tool life. Inspect tap condition regularly; a worn or damaged tap should be replaced before continuing production to avoid thread damage or tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20 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 Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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 (HSS-E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.15 inches (80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.598 inches (1 inch nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\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: 260\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.038 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: 2630005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51748735942962,"sku":"2630005","price":97.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1616050f38bc96b6c6ad602206df52c1.jpg?v=1788897525","url":"https:\/\/voomisupply.com\/products\/osg-2630005-spiral-point-tap-1-4-20-unc-tin-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
