Built from high speed steel with a bright finish, this tap cuts a 1\/4-20 UNC right-hand thread and is engineered to push chips forward through the hole rather than packing them into the flute, reducing the risk of tap breakage. With 2 flutes, a plug chamfer, and an H11 thread limit designation, it is suited for use in machine tapping operations where dimensional accuracy and consistent thread quality are required. The 2.5-inch overall length accommodates standard tapping chucks and holders used in both manual and CNC setups.\u003c\/p\u003e\u003cp\u003eThis tap is used in through-hole threading of alloy steel, aluminum, and carbon steel workpieces in shop, manufacturing, and maintenance environments. The 1\/4-20 UNC thread form is one of the most common fastener standards in general mechanical assembly, making this tap a routine tool for machinists, maintenance mechanics, and fabricators working on structural components, brackets, enclosures, and machine parts. The plug chamfer style requires a pre-existing lead or a starting hole drilled to the correct tap drill size before use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSpiral point design pushes chips forward, ideal for through-hole tapping operations\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction provides wear resistance in alloy steel, aluminum, and carbon steel\u003c\/li\u003e\n\u003cli\u003ePlug chamfer for general-purpose machine tapping with standard entry conditions\u003c\/li\u003e\n\u003cli\u003eH11 thread limit ensures controlled oversize fit for plated or coated fastener applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, 1\/4-20 UNC thread form matches the most common inch-series fastener standard\u003c\/li\u003e\n\u003cli\u003eBright finish — no coating — allows direct inspection of tool condition after use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for through-hole threading in alloy steel, aluminum, and carbon steel.

Always drill the workpiece to the correct 1\/4-20 tap drill diameter before tapping. Secure the workpiece firmly and ensure proper alignment to avoid tap deflection or breakage. Use an appropriate cutting fluid for the material being tapped to extend tool life and improve thread finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Through-Hole Threading\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: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\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: 1011\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: C57135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51711808700722,"sku":"C57135","price":26.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05b8475e9695f707891224b182ac80d4.jpg?v=1788479855","url":"https:\/\/voomisupply.com\/products\/cleveland-c57135-spiral-point-tap-1-4-20-unc-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
