Straight flute geometry makes this tap well suited for through-hole and blind-hole applications in softer workpiece materials where chip evacuation is less of a concern. The plug chamfer eases starting and distributes cutting load across the first few threads. Manufactured from high speed steel with a bright uncoated finish, the K008632AS delivers consistent thread quality in production and maintenance environments. At 5.125 inches overall length with a 2.5-inch thread length, it handles standard threading depths on 1-inch fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in machining, maintenance, and fabrication settings where 1-inch UNC threaded holes are required. Typical applications include structural fabrication, heavy equipment repair, die and mold work, and general industrial maintenance where 1-8 UNC is the standard coarse thread specification. It is installed by machinists, millwrights, and maintenance technicians using a tap wrench or machine tapping setup. The 2B class of fit produces standard commercial-grade thread tolerances appropriate for most bolted assemblies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-8 UNC thread form with 2B class of fit for standard commercial thread tolerance\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) for easier starting and reduced entry torque\u003c\/li\u003e\n  \u003cli\u003e4 straight flutes suited for through-hole and short blind-hole applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides good wear resistance across a range of materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eH6 thread limit for controlled oversize to accommodate plating or standard fit requirements\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction; no coolant-through feature\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in any application requiring a 1-8 UNC 2B class internal thread.

Apply appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Use a tap guide or machine spindle to maintain perpendicularity and prevent tap breakage, especially at the start of the cut. If tapping by hand, back off the tap periodically to break chips and clear the flutes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1-8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\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: H6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\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: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.800 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.600 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: K008632AS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51738718634290,"sku":"K008632AS","price":148.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5226d1b0e7ee6ca956854aa67e5d16d7.jpg?v=1788803347","url":"https:\/\/voomisupply.com\/products\/hertel-k008632as-straight-flute-tap-1-8-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
