Built from high speed steel and finished with a Titanium Nitride (TiN) coating, it delivers improved surface hardness and extended tool life compared to uncoated HSS tooling. The mill measures 9\/16 inches in diameter with a 1-3\/8 inches length of cut, a 1\/2 inch straight shank, and a 3-3\/8 inches overall length. It features four spiral flutes with a 30-degree right-hand helix and is centercutting, allowing both plunge and side milling. This tool is intended for machinists and toolroom professionals running manual mills or CNC machining centers.\u003c\/p\u003e\u003cp\u003eThe C33209 is suited for milling cast iron, non-ferrous metals, and steel in both production and job-shop environments. The HG-4C series designation identifies this as a general-purpose high-geometry end mill appropriate for slotting, profiling, and peripheral milling at moderate cutting speeds. The Weldon flat shank option supports positive retention in side-lock toolholders, reducing pullout risk in interrupted cuts or deep-slot operations. This tool is a regular-length configuration, making it a standard choice for setups where extended reach is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces friction for longer tool life on ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003e30-degree right-hand helix spiral flutes promote efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with Weldon flat for secure retention in side-lock holders\u003c\/li\u003e\n\u003cli\u003eFour flutes provide a balance of chip clearance and surface finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank or Weldon flat toolholders with a 1\/2 inch bore.

Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder and torque the set screw against the Weldon flat to prevent axial pullout. Verify runout with a dial indicator before beginning the cut, and select cutting parameters appropriate for high speed steel in the workpiece material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-3\/8 inches (1.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-3\/8 inches (3.375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches (0.5 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Titanium Nitride (TiN)\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\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\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: C33209\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51691292754226,"sku":"C33209","price":125.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7493305b8c3a3fb327f9227338cfb0f.jpg?v=1788282814","url":"https:\/\/voomisupply.com\/products\/cleveland-c33209-square-end-mill-9-16-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
