It is designed for cutting internal threads in both blind holes and through-holes across a range of ferrous and non-ferrous materials. With 4 straight flutes and a right-hand thread direction, this tap is suited for manual tapping operations in machine shops, maintenance facilities, and production environments. It carries a Class of Fit 3B designation and a Thread Limit of H4, making it appropriate for standard tolerance threaded assemblies requiring consistent fit.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in applications requiring a full-depth thread close to the bottom of a blind hole or through a workpiece. Its bottoming chamfer produces threads nearly to the base of the hole, making it the correct choice when thread engagement must start as close to the bottom as possible. Machinists and tooling technicians install this tap by hand or with a tap wrench in conjunction with proper cutting fluid to extend tool life and maintain thread quality.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003e4-flute straight flute geometry provides rigidity and chip clearance during hand tapping\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers durability across a broad range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for use with cutting fluids and oils\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, Class 3B fit, H4 thread limit for standard tolerance assemblies\u003c\/li\u003e\n  \u003cli\u003eCompatible with both blind hole and through-hole threading applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for threading alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces requiring a 1-8 UNC internal thread to Class 3B tolerances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists or tooling technicians using a calibrated tap wrench or suitable hand-tapping fixture. Power down any associated machinery and secure the workpiece before beginning the tapping operation. Always use an appropriate cutting fluid or tapping oil matched to the workpiece material to reduce friction and prevent tap breakage. Do not force the tap; back off periodically to clear chips, especially in blind hole applications.\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\u003eThreads per Inch\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Bottoming\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 2.5 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 Length\u003c\/strong\u003e: 0.8125 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\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel, Free-Machining Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1003\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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54925\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51715310027058,"sku":"C54925","price":183.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a5cb4bdd1813e708519de5d4f0455739.jpg?v=1788511876","url":"https:\/\/voomisupply.com\/products\/cleveland-c54925-hand-tap-1-8-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
