Manufactured from high speed steel with a bright uncoated finish, it provides reliable cutting performance in a range of ferrous and non-ferrous materials. The tap features a 3-flute straight flute geometry and a right-hand thread direction. With an overall length of 2.9375 inches and a thread length of 1.25 inches, it is sized for standard hand-tapping operations in tool rooms, maintenance shops, and production environments. Installation is performed by hand using a standard tap wrench.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading blind holes where full thread depth to the bottom of the bore is required. The bottoming chamfer — typically 1 to 2 threads of lead — allows the tap to cut threads as close to the bottom of a hole as possible. It is commonly used in machining, fabrication, repair, and assembly applications involving 3\/8-16 UNC fastener holes. The H1 thread limit designates a tight tolerance class appropriate for general-purpose threading where close-fit thread accuracy is needed.\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\u003e3\/8-16 UNC thread form, right-hand cut\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup affecting thread tolerance\u003c\/li\u003e\n  \u003cli\u003eH1 thread limit for controlled, close-tolerance thread fit\u003c\/li\u003e\n  \u003cli\u003e3-flute straight flute design for balanced cutting action in hand-tapping operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard replacement or working tap for any application requiring a 3\/8-16 UNC bottoming hand tap with H1 thread limit and straight flute geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is intended for hand-tapping use with a standard tap wrench. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 3\/8-16 UNC threads before tapping. Apply cutting fluid appropriate for the workpiece material to reduce friction and extend tap life. Back off the tap periodically to break chips and avoid binding, particularly in deeper blind holes.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\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: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3810 inches\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\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: K011090AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727393390898,"sku":"K011090AS","price":66.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb1d6f6cc3dd992b7419407a94260b11.jpg?v=1788677251","url":"https:\/\/voomisupply.com\/products\/hertel-k011090as-bottoming-hand-tap-3-8-16-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
