Built from high speed steel (HSS) with a bright, uncoated finish, it features a bottoming chamfer for threading close to the bottom of a blind hole. The right-hand, 3-flute geometry provides balanced cutting action and adequate chip clearance for the small thread size. At 1.813 inches overall length with a 0.500-inch thread length, this tap is suited to precision threading work in small-fastener applications across machining, fabrication, and maintenance environments.\u003c\/p\u003e\u003cp\u003eThe C54117 is intended for use in manual tapping operations by machinists, tool-and-die makers, and maintenance technicians. The bottoming chamfer style makes it appropriate as the finishing tap in a tap set sequence where threads must extend to near the base of a blind hole. It is also suitable for through-hole threading when full thread engagement close to a shoulder is required. The H2 thread limit supports standard 2B class-of-fit tolerances common in general industrial and mechanical assembly work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBottoming chamfer for threading to the base of blind holes\u003c\/li\u003e\n\u003cli\u003e3-flute straight-flute design for balanced cutting in small thread sizes\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 suitable for use with cutting fluids\u003c\/li\u003e\n\u003cli\u003eH2 thread limit maintains 2B class-of-fit tolerance\u003c\/li\u003e\n\u003cli\u003eRight-hand thread direction, 3-48 UNC designation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for cutting 3-48 UNC threads to a 2B class-of-fit standard; compatible with workpiece materials including alloy steel, aluminum, carbon steel, and free-machining stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tap is intended for hand tapping operations using a tap wrench or T-handle holder. Secure the workpiece firmly before tapping and apply an appropriate cutting fluid for the workpiece material to reduce heat and extend tap life. Use a bottoming tap only after a taper or plug tap has established the thread in the hole to avoid excessive torque on the tool. Inspect the tap for wear or chipping before each use, as small-diameter taps are susceptible to breakage if forced into a misaligned or undersized hole.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\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\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 Type\u003c\/strong\u003e: Straight\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\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\u003eCoolant Through\u003c\/strong\u003e: No\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: C54117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51710310678834,"sku":"C54117","price":27.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/01dd1b1254b2182d972cfcc01dd7cb54.jpg?v=1788465437","url":"https:\/\/voomisupply.com\/products\/cleveland-c54117-hand-tap-3-48-unc-bottoming-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
