Manufactured from powdered metal high-speed steel (PM-HSS) with a TiCN coating, this tap handles demanding applications including hardened steel, stainless steel, alloy steel, die steel, aluminum, and carbon steel. The bottoming chamfer with 1 to 1.5 chamfered threads allows threading to the bottom of a blind hole with minimal runout depth. Thread size is 10-24 UNC with a right-hand thread direction and an H6 thread limit for controlled tolerance. This tap is part of the OSG EXOTAP VP-NRT series, specified by machinists and tool-and-die professionals in precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThe OSG 1405005108 is suited for blind hole threading operations in ferrous and non-ferrous materials across a wide range of industries including aerospace, automotive, and general machining. Its bottoming chamfer design makes it the correct choice when full thread depth is required close to the bottom of a drilled hole. The PM-HSS construction and TiCN coating extend tool life in abrasive or high-hardness materials such as stainless steel and hardened steel. The tap runs without coolant-through capability, making it appropriate for standard CNC tapping cycles or manual tap holders in production and job-shop settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10-24 UNC right-hand thread form with H6 thread limit for precise tolerance control\u003c\/li\u003e\n\u003cli\u003eBottoming chamfer with 1 to 1.5 chamfered threads for threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003ePowdered metal high-speed steel construction for improved wear resistance over conventional HSS\u003c\/li\u003e\n\u003cli\u003eTiCN coating reduces friction and extends tool life in stainless steel, alloy steel, and hardened steel\u003c\/li\u003e\n\u003cli\u003ePart of the EXOTAP VP-NRT series engineered for cold-forming thread applications\u003c\/li\u003e\n\u003cli\u003eCompatible with multiple material groups: P (alloy and carbon steel), M (stainless steel), N (aluminum and non-ferrous)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for blind hole thread forming in materials including alloy steel, aluminum, carbon steel, die steel, hardened steel, and stainless steel.

Always drill the correct form tap pilot hole diameter for 10-24 UNC before starting — form taps require a larger pilot hole than cut taps and the correct size is critical for thread quality and tool life. Secure the workpiece and ensure the tap is aligned axially with the drilled hole before beginning the tapping cycle. Use appropriate tapping fluid or cutting oil for the workpiece material to minimize heat buildup and extend tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 10-24 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfered Threads\u003c\/strong\u003e: 1 to 1.5P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.4921 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapping Depth\u003c\/strong\u003e: 0.8660 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1940 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.1520 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Powdered Metal High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Die Steel, Hardened Steel, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: EXOTAP VP-NRT (14050)\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: 1405005108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51727762260274,"sku":"1405005108","price":70.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce0fa499b6c47459e08e960f10647754.jpg?v=1788681919","url":"https:\/\/voomisupply.com\/products\/osg-1405005108-thread-forming-tap-10-24-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
