It cuts a 1\/2-13 UNC internal thread using three right-hand flutes set at a 52-degree helix angle, which efficiently evacuates chips upward and out of the hole during the tapping operation. The tap is manufactured from high speed steel and treated with an oxide finish to reduce friction and improve wear resistance. With a 2B class of fit and H3 thread limit, it produces threads suited to standard fastener assembly tolerances. Machinists, toolroom technicians, and CNC operators handling ferrous and non-ferrous work are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for blind hole threading in aluminum, non-ferrous metals, and steel. The spiral flute geometry makes it particularly effective when chips cannot exit through the bottom of the hole, as the flutes carry chips back toward the shank. It is a plug chamfer style, requiring a pre-existing started hole and delivering a full thread close to the bottom of a blind bore. The overall length of 3.375 inches and shank diameter of 0.367 inches make it compatible with standard tap holders and quick-change tapping heads used in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e52-degree helix angle promotes reliable upward chip evacuation in blind holes\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction provides strength and heat resistance in steel and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eOxide finish reduces friction and extends tool life during tapping operations\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer style allows threading close to the bottom of a blind bore\u003c\/li\u003e\n  \u003cli\u003eH3 thread limit and 2B class of fit meet standard fastener assembly tolerances\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute and right-hand thread configuration for conventional CNC and manual tapping setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard tap holders, quick-change tapping heads, and CNC machining centers that accept a 0.367-inch shank diameter.

Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for a 1\/2-13 UNC thread before tapping. Apply cutting fluid appropriate to the workpiece material to reduce heat buildup and extend tool life. Never force a tap into an undersized hole, as this can cause tap breakage and damage the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-13\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: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Style\u003c\/strong\u003e: Plug\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\u003eHelix Angle\u003c\/strong\u003e: 52 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads per Inch\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.73 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.367 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.275 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.4375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: Blind Hole Threading\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Non-Ferrous Metal, Steel\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: Oxide\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: 1093BO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 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: C58452\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51714813264178,"sku":"C58452","price":100.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8cb61a5c2942927cb32cf7249e2a6f1a_b951aeaf-224a-4930-81f6-33b42407e9f3.jpg?v=1788506539","url":"https:\/\/voomisupply.com\/products\/cleveland-c58452-spiral-flute-tap-1-2-13-unc-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
