Manufactured from high-speed steel with a bright, uncoated finish, this tap produces 13\/16-20 UNEF right-hand threads and is built to reach close to the bottom of blind holes. The bottoming chamfer allows threading to within one to two threads of the hole bottom, making it the right choice when full thread depth in a shallow blind bore is required. Six flutes provide a good balance of chip clearance and cutting edge support. It is used by machinists and maintenance trades in production and repair applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading operations in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. At 4-15\/32 inches overall length with a 2-inch thread length, it fits standard tap holders and extension handles used on drill presses, CNC machining centers, and manual tapping arms. The H3 thread limit provides a controlled fit class suitable for precision thread engagement in standard UNEF assemblies. It is most commonly used in applications that require fine thread pitches for thin-wall or close-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eSix flutes for balanced chip clearance and cutting edge support\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction handles both ferrous and non-ferrous workpieces\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for controlled, consistent thread fit\u003c\/li\u003e\n  \u003cli\u003eRight-hand, 13\/16-20 UNEF thread form for fine-pitch applications\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids across a broad material range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel workpieces.

Ensure the workpiece is securely fixtured and the tap is properly aligned with the pre-drilled pilot hole before beginning the threading cycle. Use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread finish. Inspect the tap for wear or damage before each use, and never force a tap that has stalled or bound in the hole.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 13\/16-20 UNEF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNEF\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: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2 inches (1.5 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-15\/32 inches (4.469 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.652 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.6875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.489 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.382 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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: 101N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.48 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: 1682000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51743002526002,"sku":"1682000","price":133.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5143419fa97e163066ad2289bda9bbd2.jpg?v=1788841439","url":"https:\/\/voomisupply.com\/products\/osg-1682000-straight-flute-tap-13-16-20-unef-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
