Manufactured from high-speed steel (HSS) with a bright, uncoated finish, this reamer features a helical flute design and right-hand cutting direction. The small end diameter measures 0.3297 inches and the large end measures 0.4220 inches, conforming to the 1:48 taper rate standard for No. 7 taper pins. Overall length is 6.3125 inches with a flute length of 4.4375 inches. Machinists and maintenance technicians rely on this tool for accurate taper pin hole preparation in shafts, hubs, and mechanical assemblies.\u003c\/p\u003e\u003cp\u003eThis reamer is suited for general-purpose use on aluminum, steel, and steel alloy workpieces. Typical applications include preparing taper pin holes in mechanical power transmission components, machine tool repair, and precision assembly work. The straight shank measures 13\/32 inches (0.4063 inches decimal) and fits standard drill chucks and collet holders used in milling machines, drill presses, and hand drilling operations. It is part of the CLEVELAND Series 650 taper pin reamer line.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNo. 7 taper pin size with a 1:48 taper rate conforming to ASME taper pin standards\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction for durability across aluminum, steel, and steel alloy materials\u003c\/li\u003e\n\u003cli\u003eHelical flute geometry for smoother cutting and improved chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction with left-hand spiral for reduced chatter and improved finish\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for general-purpose machining environments\u003c\/li\u003e\n\u003cli\u003eStraight shank for compatibility with standard drill chucks and collet holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with No. 7 standard taper pins in aluminum, steel, and steel alloy workpieces.

Secure the straight shank firmly in a drill chuck or collet before use, and ensure the workpiece is properly fixtured to prevent movement. Apply cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Do not exceed recommended feed rates for HSS tooling on the material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Pin Size\u003c\/strong\u003e: No. 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.3297 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLarge End Diameter\u003c\/strong\u003e: 0.4220 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Rate\u003c\/strong\u003e: 1:48\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4.4375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.4063 inches (13\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpiral Direction\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum, Steel, Steel Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 650\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: C24242\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51720097169714,"sku":"C24242","price":191.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ebe7f78935b085fa478156fb601bb95d.jpg?v=1788560884","url":"https:\/\/voomisupply.com\/products\/cleveland-c24242-no-7-taper-pin-reamer-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
