Built from high speed steel (HSS) with a bright, uncoated finish, this tap features a taper chamfer that gradually introduces the cutting edges into the workpiece for controlled thread engagement. It runs right-hand thread direction to a Class 2B fit with an H2 thread limit, making it suitable for standard tolerance threaded assemblies. The overall length is 1.813 inches, with a 0.5-inch thread length. It is installed by machinists and toolroom technicians working with hand tapping equipment or tapping fixtures.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for use in light-duty threading applications across a range of materials including alloy steel, carbon steel, aluminum, and free-machining stainless steel. The taper chamfer style makes it particularly effective as a starting tap when initiating threads in a new hole. With three straight flutes, chip evacuation is straightforward in through-hole applications, and it works in blind holes where chip management is carefully controlled. Typical applications include small-fastener thread production in fabrication, maintenance, and repair environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-48 UNC thread size with right-hand direction and Class 2B fit\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit for standard tolerance control\u003c\/li\u003e\n  \u003cli\u003eTaper chamfer for gradual thread engagement and ease of starting\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for durability across a variety of workpiece materials\u003c\/li\u003e\n  \u003cli\u003e3-flute straight-flute geometry supports both blind hole and through-hole threading\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect thread tolerance in small-diameter applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard hand tapping operations on alloy steel, carbon steel, aluminum, and free-machining stainless steel workpieces requiring 3-48 UNC internal threads to a Class 2B fit.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap is installed by machinists or maintenance technicians using a tap wrench or tapping fixture aligned perpendicular to the workpiece surface. Always use an appropriate cutting fluid for the workpiece material to extend tool life and improve thread quality. For blind hole work, monitor chip accumulation and back off periodically to clear the flutes. Do not apply excessive torque, especially in harder materials, as small-diameter taps are susceptible to breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\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\u003eChamfer\u003c\/strong\u003e: Taper\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: 0.5 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\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: 1001\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: C54115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51700439384370,"sku":"C54115","price":27.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c9b81432807c66192923fef297df8e7.jpg?v=1788390351","url":"https:\/\/voomisupply.com\/products\/cleveland-c54115-hand-tap-3-48-unc-taper-rh-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
