Built from high speed steel (HSS) with a bright\/uncoated finish, it cuts a 1\/4-28 UNF right-hand thread to a 3B class of fit. The fast-helix flute geometry at 52 degrees pulls chips up and out of the hole during tapping, which is critical in blind hole applications where chip packing causes tap breakage. Thread length is 0.63 inches over a 2.5-inch overall length. This tap is sized for use with standard tap wrenches or machine tapping heads and is installed by licensed machinists, tool and die makers, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThe C58564 is suited for blind hole threading operations in alloy steel, carbon steel, and stainless steel workpieces. The plug chamfer — typically 3 to 5 threads — provides a balance between starting ease and thread length, making it appropriate for general-purpose machine tapping and hand tapping where through-hole access is not available. It fits Series 1093 and 1094 tooling lines and is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e52-degree fast helix flute design evacuates chips upward out of blind holes during cutting\u003c\/li\u003e\n  \u003cli\u003e1\/4-28 UNF thread form with 3B class of fit for standard tolerance threaded assemblies\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit for consistent fit control in production and maintenance applications\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides durability across alloy steel, carbon steel, and stainless steel\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer for versatile hand or machine tapping starts\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish — no coating buildup risk on close-tolerance threads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in alloy tool steel, carbon steel, and stainless steel workpieces requiring a 1\/4-28 UNF 3B class of fit blind hole thread.

Always use the correct tap drill size for the 1\/4-28 UNF thread form and apply appropriate cutting fluid to extend tool life, particularly in stainless steel. Do not reverse the tap under power — back out manually to break and clear chips when hand tapping blind holes. Inspect the tap for wear or chipping before each use.\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 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 3B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Style\u003c\/strong\u003e: Fast Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 52 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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\u003eNeck Length\u003c\/strong\u003e: 0.39 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.191 inches\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\u003eApplication\u003c\/strong\u003e: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Alloy Tool Steel, Carbon Steel, Stainless Steel\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: 1093, 1094\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: C58564\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699704987954,"sku":"C58564","price":41.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1bd2eb4f591e95b94fd3ad16ff08e2b4.jpg?v=1788379536","url":"https:\/\/voomisupply.com\/products\/cleveland-c58564-spiral-flute-tap-1-4-28-unf-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
