It features a 0.250-inch cutting diameter, a 1.250-inch length of cut, and a 3\/8-inch straight-cylindrical shank with a Weldon flat for secure tool holding. A titanium nitride (TiN) coating improves surface hardness and wear resistance, extending tool life in demanding applications. The 30-degree spiral flute geometry promotes efficient chip evacuation, while the centercutting design allows both plunge and peripheral cutting. This tool is installed and operated by machinists and CNC programmers in job shop, tool room, and production settings.\u003c\/p\u003e\n\u003cp\u003eThe C33386 is suited for milling cast iron, non-ferrous metals, and steel in light to medium material removal operations. The regular-length configuration and 3-1\/16-inch overall length make it a practical choice for general-purpose profiling, slotting, and contouring on vertical machining centers and manual knee mills. Right-hand cut and right-hand flute geometry are standard for conventional spindle rotation. The HG-4C series designation identifies this tool within the CLEVELAND high-geometry end mill line, optimized for consistent performance across common workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.250-inch cutting diameter with 1.250-inch length of cut for standard-depth slotting and profiling\u003c\/li\u003e\n  \u003cli\u003e4-flute configuration provides a good balance of chip clearance and surface finish\u003c\/li\u003e\n  \u003cli\u003eTiN coating increases surface hardness and reduces friction for longer tool life\u003c\/li\u003e\n  \u003cli\u003e30-degree helix spiral flute promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch shank with Weldon flat provides positive, slip-resistant tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with milling operations on cast iron, non-ferrous metals, and steel workpieces.

Confirm spindle rotation is set to right-hand (clockwise viewed from above) before engaging the cut. Select appropriate feed rate and depth of cut based on workpiece material and machine rigidity. Inspect the cutting edges and TiN coating for wear before each use and replace when chipping or coating breakdown is observed.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.250 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/16 inches\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: 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\u003eFinish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Steel\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\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: C33386\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51695410774322,"sku":"C33386","price":66.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/378e80cb6c296e793bc004ce3e84aa8a.jpg?v=1788334720","url":"https:\/\/voomisupply.com\/products\/cleveland-c33386-square-end-mill-1-4-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
