Manufactured from high speed steel (HSS) with a titanium nitride (TiN) coating, it offers improved surface hardness and wear resistance over uncoated HSS tooling. The cutting diameter is 0.375 inches, the length of cut is 2.5 inches, and the overall length is 4.25 inches, placing it in the extra-long length category. Right-hand cut and right-hand spiral flutes at a 30-degree helix angle provide efficient chip evacuation. This tool is centercutting, allowing plunge entry into the workpiece. It is installed and used by machinists and CNC operators in job shops and production environments.\u003c\/p\u003e\u003cp\u003eThe C33444 is suited for milling cast iron, non-ferrous metals, and steel. Its extra-long length of cut — 2.5 inches — makes it appropriate for deep slot milling, side milling, and profiling operations where standard-length end mills cannot reach. The straight cylindrical shank with Weldon flat accepts standard ER collets and side-lock holders with a 3\/8-inch bore. The HG-4C series is built for general-purpose machining where a balance of tool life and cut performance is required across a range of workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4-flute spiral geometry with 30-degree right-hand helix for efficient chip flow\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with TiN coating for extended tool life over bare HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge cuts without pre-drilling\u003c\/li\u003e\n\u003cli\u003eExtra-long length of cut (2.5 inches) reaches deep slots and pockets\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with Weldon flat for secure side-lock or collet holding\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute — compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe C33444 is a general-purpose HSS TiN-coated square end mill in the Cleveland HG-4C series, suitable for use in any 3\/8-inch end mill holder or collet chuck on manual mills and CNC machining centers.

Seat the shank fully in the holder and torque the set screw against the Weldon flat — do not clamp on the fluted section. Verify runout with a dial indicator before beginning a production cut. Cutting parameters including speed and feed should be selected based on workpiece material and machine rigidity; consult the Cleveland tooling data sheet for recommended starting values.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill 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 (HSS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.5 inches (2-1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.25 inches (4-1\/4 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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical with Weldon Flat\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: Extra Long\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\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: C33444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51703918952754,"sku":"C33444","price":84.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ff8406f3aaed7c7898727676903cff7.jpg?v=1788419457","url":"https:\/\/voomisupply.com\/products\/cleveland-c33444-square-end-mill-3-8-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
