It cuts a 1\/4-28 UNC right-hand thread and uses a 2-flute spiral point geometry to push chips forward ahead of the cutting zone, keeping the flutes clear during production runs. The tap is manufactured from high speed steel with an oxide finish for basic corrosion resistance and reduced galling. Overall length is 2.5 inches with a thread length of 1.0 inch, making it suited for standard-depth through-hole applications in machining, maintenance, and fabrication environments. Licensed machinists, millwrights, and maintenance mechanics are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis tap is intended for through-hole threading in cast iron and steel workpieces. The plug chamfer provides a gradual lead-in that distributes cutting load across several threads at entry, which makes it practical for both hand tapping and machine tapping in drill press, CNC, or tapping arm setups. The 2B class of fit produces a standard commercial thread tolerance suitable for the majority of fastener and threaded insert applications at the 1\/4-28 UNC specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSpiral point geometry pushes chips forward, reducing clogging in through-hole operations\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across cast iron and steel materials\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer with 3-5 thread lead-in distributes cutting load at entry\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit holds consistent tolerance for 2B class of fit threads\u003c\/li\u003e\n  \u003cli\u003eOxide finish provides basic surface protection during storage and use\u003c\/li\u003e\n  \u003cli\u003eRight-hand thread direction, 28 threads per inch, UNC standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for through-hole threading of cast iron and steel at the 1\/4-28 UNC thread specification.

Use an appropriate cutting fluid or tapping compound when threading steel or cast iron to extend tool life and improve thread finish. Apply consistent, controlled feed pressure whether hand tapping or machine tapping, and do not exceed the tap's rated material application range. Machinists should verify spindle alignment before powered tapping operations to avoid tap breakage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-28 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\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\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\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: Oxide\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: Cast Iron, 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: 1.0 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.255 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 28\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: 1011BO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: C57622\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51722669359410,"sku":"C57622","price":23.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4719e911757f40f89c1269f0f192da87.jpg?v=1788594278","url":"https:\/\/voomisupply.com\/products\/cleveland-c57622-spiral-point-tap-1-4-28-unc-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
