Built from high speed steel with a bright, uncoated finish, this tap is suited for both blind hole and through-hole threading operations. It features a 3-flute straight flute geometry and a right-hand thread direction, conforming to UNC thread standards with a 2B class of fit and H2 thread limit. The overall length is 1.75 inches, and the thread length is 0.44 inches. Licensed machinists and tool-and-die technicians reach for this tap when close-tolerance internal threading is required on small-diameter fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is used in precision machining environments including job shops, maintenance facilities, and production floors. It is appropriate for threading blind holes and through-holes in materials such as alloy steel, aluminum, carbon steel, and free-machining stainless steel. The bottoming chamfer style allows threads to be cut close to the bottom of a blind hole, making it the right choice when thread engagement depth is critical. It belongs to Cleveland Series 1003 and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer for threading close to the bottom of blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a range of workpiece materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish — no coating buildup that could affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003e3-flute straight flute design provides chip clearance and stable cutting action\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 2B class of fit, H2 thread limit for standard tolerance control\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 cutting 2-56 UNC internal threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces.

Before tapping, confirm the correct drill size has been used to produce the pilot hole per standard 2-56 tap drill charts. Apply appropriate cutting fluid for the workpiece material to reduce friction and extend tap life. Never force a tap against resistance — back it off periodically to break chips and prevent tap breakage, 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: 2-56\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: 56\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: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.75 inches (44.45 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches (3.58 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.110 inches (2.79 mm)\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1003\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: CLEVELAND\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C54091\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694610415922,"sku":"C54091","price":33.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28bf6f6e78892c4c1551dab00d067fe2.jpg?v=1788326243","url":"https:\/\/voomisupply.com\/products\/cleveland-c54091-hand-tap-2-56-bottoming-hss-bright-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
