Built from high speed steel with a bright uncoated finish, this bottoming-chamfer tap cuts close to the bottom of blind holes where plug or taper taps cannot reach. The 3-flute geometry provides strong chip clearance in a compact profile suited to the small 3-56 thread size. With an overall length of 1.813 inches and a thread length of 0.500 inches, it is sized for precise work in tight-tolerance assemblies. Machinist and tool-and-die professionals rely on this style of tap for high-accuracy threading in small fastener applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in manual tapping operations on a range of metallic materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel. The 3-56 UNF thread form is commonly found in small instrument, electronic, and precision mechanical assemblies. The bottoming chamfer makes this an appropriate choice when thread engagement must start at or very near the bottom of a blind hole. It is sold individually and is compatible with standard tap wrenches sized for the 0.141-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBottoming chamfer allows threading to the base of blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across common ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish for direct use without additional surface treatment\u003c\/li\u003e\n  \u003cli\u003e3-flute straight-flute design for efficient chip evacuation in small-diameter tapping\u003c\/li\u003e\n  \u003cli\u003eClass 2B thread fit and H2 thread limit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, matching the standard 3-56 UNF fastener convention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for cutting 3-56 UNF internal threads in alloy steel, aluminum, carbon steel, and free-machining stainless steel workpieces in blind-hole and through-hole configurations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by a machinist or tool-and-die technician using a standard manual tap wrench sized to accept the 0.141-inch shank. Ensure the workpiece is securely fixtured and the tap is started straight and perpendicular to the hole axis to avoid thread distortion or tap breakage in small-diameter work. Apply an appropriate cutting fluid for the workpiece material before and during tapping. Do not force the tap; back off 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: 3-56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTap Type\u003c\/strong\u003e: Standard Hand Tap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer\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\u003eFlute Style\u003c\/strong\u003e: Straight Flute\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.813 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.500 inches (12.70 mm)\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading, Through-Hole Threading\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  \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: C54122\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51696804888882,"sku":"C54122","price":30.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a1d7b547f9a7a958110dfeb3ba27877.jpg?v=1788346454","url":"https:\/\/voomisupply.com\/products\/cleveland-c54122-hand-tap-3-56-unf-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
