It carries a 0.625-inch (5\/8 inch) cutting diameter with a 2-inch length of cut and a matching 0.625-inch straight shank. The 30-degree helix angle promotes efficient chip evacuation, and the spiral flute geometry supports smooth cutting action across a range of workpiece materials. At 4.125 inches overall length, this is a long-series tool suited for reaching into deeper pockets or stepped features. It is centercutting, allowing plunge entry directly into the workpiece without a pilot hole.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on cast iron, non-ferrous metals, and steel, covering the most common materials encountered in general machining, tool and die work, and production milling. The uncoated high speed steel construction is well suited to conventional milling setups on manual knee mills, CNC machining centers, and bridgeport-style machines where coolant is applied. The Weldon flat shank option provides positive drive retention in standard end mill holders. It belongs to the HG-2 long series line, which is sized for jobs where standard-length tools lack the reach.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for efficient chip evacuation and reduced chatter\u003c\/li\u003e\n\u003cli\u003eLong-series HG-2 geometry provides extended reach into deep pockets\u003c\/li\u003e\n\u003cli\u003eStraight shank with Weldon flat for secure holder retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral configuration\u003c\/li\u003e\n\u003cli\u003eUncoated HSS construction compatible with flood coolant use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style general-purpose end mill compatible with standard 5\/8-inch end mill holders, collet chucks, and Weldon-style set-screw tool holders used in vertical milling machines and CNC machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before loading or changing the tool. Seat the shank fully into the holder and tighten set screws against the Weldon flat to the holder specification. Inspect the cutting edges for chipping before use; do not run a damaged end mill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.125 inches (4-1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\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-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\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: C41721\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51718755549490,"sku":"C41721","price":109.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2edc0d8b7333a68d29d6939dcd115cbe.jpg?v=1788555388","url":"https:\/\/voomisupply.com\/products\/cleveland-c41721-square-end-mill-0-625in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
