It features a 5\/16-18 UNC thread form with a modified bottoming chamfer, making it suitable for threading holes that require minimal thread runout at the bottom. The tap is manufactured from powdered metal and coated with TiCN (Titanium Carbonitride) for improved wear resistance and tool life in demanding materials. With an H5 thread limit and a 2B class of fit, it produces threads within standard tolerance ranges for general mechanical assembly. Installation is performed by licensed machinists or tool-and-die professionals in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for machine tapping applications in CNC machining centers, drill presses, and tapping machines where controlled feed and speed are maintained. It is well suited for threading hardened steel and alloy steel components in industrial, automotive, and general manufacturing settings. The modified bottoming chamfer allows the tap to cut threads close to the bottom of blind holes, making it a practical choice when full thread depth near the bottom of the bore is required. The right-hand thread direction is standard for the vast majority of fastener and assembly applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-18 UNC thread form with modified bottoming chamfer for near-bottom threading in blind holes\u003c\/li\u003e\n  \u003cli\u003e5 flutes for improved chip control and thread form accuracy in machine tapping operations\u003c\/li\u003e\n  \u003cli\u003ePowdered metal construction provides increased toughness and wear resistance compared to standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating enhances surface hardness and reduces friction when cutting hardened steel and alloy steel\u003c\/li\u003e\n  \u003cli\u003eH5 thread limit with 2B class of fit for consistent, within-tolerance thread production\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use in hardened steel and alloy steel.

Always ensure the spindle speed and feed rate are matched to the material hardness and tap geometry before beginning the cut. Power down and lock out the machine before changing or inspecting the tap. Do not attempt to reverse a broken tap under power; follow standard tool-extraction procedures to avoid workpiece damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Machine, Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-18 UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H5\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: 1-1\/8 inches (1.125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2-23\/32 inches (2.719 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.318 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 1.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN (Titanium Carbonitride)\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: Hardened Steel, Alloy Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 10051\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: 1005111808\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727907488050,"sku":"1005111808","price":80.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51dda9fb7b6fa26ecd8ad5e28845e019.jpg?v=1788684341","url":"https:\/\/voomisupply.com\/products\/osg-1005111808-straight-flute-tap-5-16-18-unc-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
