The cutter measures 0.25 inches in diameter with a 1.25 inch length of cut, a 0.375 inch straight-cylindrical shank with Weldon flat, and a 3.0625 inch overall length. Three right-hand spiral flutes with a 30-degree helix angle provide efficient chip evacuation and smooth cutting action. The centercutting geometry allows direct plunge entry into the workpiece without a pre-drilled hole. This tool belongs to Cleveland's HG-3 long series, intended for reach-demanding applications. It is uncoated and ready for use with standard cutting fluids.\u003c\/p\u003e\n\u003cp\u003eThe C39733 is suited for milling cast iron, non-ferrous metals, and steel in both manual and CNC machining setups. The long-series configuration gives machinists additional reach for slotting, profiling, and peripheral milling in deeper pockets or stepped features where a standard-length end mill would fall short. Right-hand cut and right-hand flute orientation match the conventional spindle rotation of most vertical and horizontal mills. The straight shank with Weldon flat seats securely in side-lock and collet holders commonly found in production toolrooms.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.25 inch cutting diameter with 1.25 inch length of cut for deep slot and pocket work\u003c\/li\u003e\n  \u003cli\u003e3 right-hand spiral flutes at 30-degree helix for efficient chip flow on ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling without pilot drilling\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction offers toughness and regrindability\u003c\/li\u003e\n  \u003cli\u003e0.375 inch straight-cylindrical shank with Weldon flat for positive grip in side-lock holders\u003c\/li\u003e\n  \u003cli\u003eLong-series HG-3 classification provides additional reach versus standard-length end mills\u003c\/li\u003e\n  \u003cli\u003eUncoated finish — compatible with most water-soluble and oil-based cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard side-lock, Weldon-flat, and collet-style tool holders accepting a 0.375 inch shank.

Seat the Weldon flat squarely against the set screw in the tool holder and torque according to the holder manufacturer's specification to prevent pullout under cutting loads. Confirm runout with a dial indicator before taking the first cut, particularly given the long-series overhang. Always verify spindle speed and feed rate against published HSS cutting data for the specific workpiece material before engaging the cutter.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (1-1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0625 inches (3-1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: C39733\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695106949426,"sku":"C39733","price":83.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/705d6cada846e7004726d1fb9c3b1737.jpg?v=1788331368","url":"https:\/\/voomisupply.com\/products\/cleveland-c39733-square-end-mill-0-25-in-3-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
