It is ground to a 5\/8-11 UNC thread form with a plug chamfer, which provides a gradual lead-in of 3 to 5 threads to ease starting and reduce torque demand. The 4-flute design offers good chip clearance in a range of ferrous and non-ferrous materials. Built from carbon steel with a bright, uncoated finish, this tap suits general-purpose threading work. Overall length is 3.8125 inches with a thread length of 1.813 inches and a shank diameter of 0.480 inches. Machinists, maintenance mechanics, and trade professionals use this tap in hand-tapping and low-speed machine applications.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for production and maintenance threading of 5\/8-11 UNC holes in carbon steel, alloy steel, aluminum, and similar machinable materials. It is well suited for repair threading, fixture fabrication, and general shop work where a standard UNC thread form is required. The plug chamfer makes it a practical first choice when threading a clean, pre-drilled hole. It is sized for use in a standard tap wrench, T-handle, or drill press tapping head.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-11 UNC thread form with 2B class of fit for standard tolerance internal threads\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead-in) for easier starting in pre-drilled through holes\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration promotes chip clearance and cutting stability\u003c\/li\u003e\n  \u003cli\u003eCarbon steel construction suited for general-purpose threading applications\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish  -  no coating buildup to affect thread tolerance\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, standard for the majority of fastener applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard straight flute plug tap for general-purpose hand and machine tapping of 5\/8-11 UNC internal threads in a variety of machinable materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eAlways use the correct drill size for a 5\/8-11 UNC thread before tapping  -  an undersized hole increases torque and risk of tap breakage. Power down any machine and secure the workpiece before beginning the tapping operation. Apply a cutting fluid appropriate to the workpiece material to reduce heat and extend tap life. Back off periodically when hand tapping to break chips and prevent tap seizure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\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: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.813 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.480 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Carbon 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\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: IRWIN HANSON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IRWIN","offers":[{"title":"Default Title","offer_id":67908294672690,"sku":"1452","price":25.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9a57695ac5fed0818d7bbc8ff785c78.jpg?v=1791183117","url":"https:\/\/voomisupply.com\/products\/irwin-hanson-1452-straight-flute-tap-5-8-11-unc-plug-chamfer","provider":"Voomi Supply","version":"1.0","type":"link"}
