Built from high speed steel (HSS), this single-end tool features a 3\/16 inch cutting diameter, a 1\/2 inch length of cut, and a 3\/8 inch straight cylindrical shank with Weldon flat. The 30-degree helix spiral flute geometry promotes efficient chip evacuation and smooth cutting action. It is centercutting, allowing plunge entry as well as standard peripheral and slot milling. Installation and use are performed by machinists and CNC operators on milling machines and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling cast iron, non-ferrous metals, and steel in both manual and CNC milling applications. The HG-4C series designation indicates a regular-length, general-purpose geometry appropriate for a wide range of slotting, profiling, and face milling tasks. The right-hand cut and right-hand flute orientation are standard for conventional spindle setups. The uncoated HSS construction makes it a cost-effective choice for lower-speed operations and materials where carbide tooling is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-flute spiral flute design for balanced cutting and chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle for smooth engagement in steel, cast iron, and non-ferrous metals\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with Weldon flat for positive tool holding\u003c\/li\u003e\n\u003cli\u003eUncoated high speed steel construction for general-purpose, lower-speed applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — standard orientation for conventional milling setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on manual and CNC milling machines accepting a 3\/8 inch straight shank.

Secure the shank fully in a collet or end mill holder, engaging the Weldon flat set screw to prevent axial pullout under load. Verify spindle speed and feed rate against the material being machined and the tool manufacturer's recommendations before operation. Never exceed the rated length of cut or apply side loads beyond the tool's design geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/8 inches\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\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\u003eSeries\u003c\/strong\u003e: HG-4C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: C41245\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51697881743666,"sku":"C41245","price":48.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5aa46b8c57602179d71accf0dfedef3f.jpg?v=1788355364","url":"https:\/\/voomisupply.com\/products\/cleveland-c41245-square-end-mill-3-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
