It cuts a 3-48 UNC thread profile using a plug chamfer to ease entry and guide chip flow forward, keeping the flutes clear during production runs. Built from high speed steel with a titanium nitride (TiN) finish, it offers increased surface hardness and wear resistance compared to uncoated HSS. The tap has a 2-flute configuration, a right-hand thread direction, and meets Class 2B fit tolerance under the H2 thread limit. Overall length is 1.813 inches with a thread length of 0.5 inches.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for through-hole threading operations in alloy steel, aluminum, and carbon steel workpieces. It is appropriate for machine tapping and hand tapping setups where a 3-48 UNC thread is required. The plug chamfer style makes it a general-purpose choice for production and maintenance work, including light fabrication, instrument assembly, and mechanical repair tasks where small-diameter unified coarse threads are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-48 UNC thread profile with plug chamfer for guided entry and forward chip ejection\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction for toughness across alloy steel, aluminum, and carbon steel\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and extends tool life versus uncoated HSS\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit, Class 2B fit for standard tolerance threading applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, 2-flute design suited for through-hole applications\u003c\/li\u003e\n  \u003cli\u003eOverall length of 1.813 inches with a 0.5-inch thread length for compact setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, and carbon steel.

Ensure the workpiece is secured and the pilot hole diameter is correct for a 3-48 UNC tap before starting. Use appropriate cutting fluid for the material being tapped. Do not force the tap if resistance increases unexpectedly, as small-diameter taps are susceptible to breakage under side load or misalignment.\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\u003eThreads per Inch\u003c\/strong\u003e: 48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Steel, Aluminum, Carbon Steel\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 2.79 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1011TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\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 CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: C55294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":67581999186226,"sku":"C55294","price":33.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22ef950ab09ace24b56a11b6e6888d2a.jpg?v=1790411778","url":"https:\/\/voomisupply.com\/products\/cleveland-controls-c55294-spiral-point-tap-3-48-unc-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
