Built from high speed steel with a titanium carbonitride (TiCN) finish, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The 1-inch cutting diameter pairs with a 4-inch length of cut and a 30-degree helix angle in a spiral flute geometry that promotes efficient chip evacuation. At 6.5 inches overall length with a 1-inch straight-cylindrical shank, this tool seats securely in standard end mill holders and Weldon flat-style collet chucks. Center-cutting geometry allows plunge entry, giving machinists added versatility in slotting and profiling operations. It is a right-hand cut, right-hand flute configuration in the Cleveland HG-4C series.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in manual knee mills and CNC machining centers in job shop, toolroom, and production environments. Primary workpiece materials include cast iron, non-ferrous metals, and steel. The regular-length classification and 2-inch-plus length-of-cut range make it a practical choice for full-depth slotting, peripheral milling, and profiling passes where a general-purpose HSS tool is specified. The TiCN coating extends tool life when cutting abrasive or harder steel grades at moderate speeds and feeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-inch cutting diameter with 4-inch length of cut for deep slotting and profiling\u003c\/li\u003e\n  \u003cli\u003e4-flute spiral geometry promotes chip evacuation and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eTiCN coating increases surface hardness and wear resistance over uncoated HSS\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle balances cutting force and chip flow in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation on most mills\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank with Weldon flat for positive tool retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1-inch end mill holders and Weldon flat collet chucks on manual mills and CNC machining centers.

Secure the shank fully into the tool holder to the minimum insertion depth required before tightening — do not grip on the flutes. Verify spindle rotation direction matches the right-hand cut configuration before engaging the workpiece. Inspect the cutting edges and TiCN coating for chips or wear before each use, and replace the tool if edge integrity is compromised.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\u003eCoating\u003c\/strong\u003e: TiCN\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: 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  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-4C\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: C33420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51714376106290,"sku":"C33420","price":294.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9536eb1bedd44123db0b0dc3cbffe42a.jpg?v=1788500509","url":"https:\/\/voomisupply.com\/products\/cleveland-c33420-square-end-mill-1-in-4-flute-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
