Built from vanadium high-speed steel with a TiCN coating, it delivers extended tool life in demanding materials including alloy steel, carbon steel, cast iron, aluminum, and die steel. The three right-hand spiral flutes pull chips up and out of the hole, making this tap well-suited for blind-hole applications where chip evacuation is critical. At 100 mm overall length, it fits standard tap holders and machine spindles used in CNC and manual tapping operations.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for use by machinists, tool and die makers, and maintenance technicians working in ferrous and non-ferrous materials. Its bottoming chamfer allows threading close to the bottom of a blind hole, which is a common requirement in fixture plates, machine components, and threaded insert applications. The coolant-through design supports through-coolant tapping for improved chip clearing and heat management at the cutting edge. It is suited for both machine tapping and rigid-tap cycles on CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eSpiral flute geometry at 15-degree helix angle promotes upward chip evacuation\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and surface hardness for longer tool life\u003c\/li\u003e\n  \u003cli\u003eVanadium high-speed steel substrate handles alloy steel, cast iron, aluminum, carbon steel, and die steel\u003c\/li\u003e\n  \u003cli\u003eCoolant-through capability supports high-speed machine tapping operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread and right-hand flute direction for standard tapping applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for tapping 3\/8-16 UNC threads in alloy steel, aluminum, carbon steel, cast iron, and die steel.

Power down and lock out any machine before changing tooling or setting tap holders. Ensure the tap is properly chucked in a rigid or floating tap holder appropriate for the machine and application. Follow the tool manufacturer and machine builder recommendations for tapping speeds and feed rates based on material hardness and hole depth.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16 UNC\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: 16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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: 15 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 9.843 inches (100 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 5.512 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.644 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.286 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: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Cast Iron, Die Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 13013\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 1301300908\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743302451506,"sku":"1301300908","price":116.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b91833722ea1a88b88c80cf01bafa0b.jpg?v=1788845337","url":"https:\/\/voomisupply.com\/products\/osg-1301300908-spiral-flute-tap-3-8-16-unc-bottoming-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
