Manufactured from high speed steel with a titanium nitride (TiN) finish, it offers increased surface hardness and wear resistance compared to uncoated HSS tooling. The 5\/16 inch cutting diameter pairs with a 3\/4 inch length of cut and a 30-degree helix angle to promote efficient chip evacuation. With four spiral flutes and centercutting capability, this end mill handles slotting, profiling, and plunge cutting in a single tool. It is sized for use in manual mills and CNC machining centers with standard collet or end mill holders.\u003c\/p\u003e\u003cp\u003eThe C33071 belongs to the Cleveland HD-4C series, a regular-length line intended for general-purpose milling in job shops, maintenance facilities, and production environments. Its right-hand cut and right-hand flute configuration suits standard spindle rotation on vertical mills. The 3\/8 inch straight-cylindrical shank with Weldon flat accommodates both collet chucks and set-screw style holders. Primary workpiece materials include cast iron, non-ferrous metals, and steel, making it a versatile choice across common trade applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDouble-end design doubles tool life before replacement is required\u003c\/li\u003e\n\u003cli\u003eTiN coating increases surface hardness and reduces friction against workpiece material\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow in steel and non-ferrous cuts\u003c\/li\u003e\n\u003cli\u003eWeldon flat on shank prevents slippage under heavy side loads\u003c\/li\u003e\n\u003cli\u003eFour-flute configuration balances chip clearance with surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard end mill holders, collet chucks, and Weldon-style set-screw holders accepting a 3\/8 inch shank.

Ensure the holder bore and shank are clean and free of chips before seating the tool. Align the Weldon flat with the set screw when using a side-lock holder to prevent axial pullout under cutting loads. Feed rate and spindle speed should be set per published HSS cutting data for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 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: 3-1\/2 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\u003eCoating\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\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical with Weldon Flat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-4C\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: C33071\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51698535825714,"sku":"C33071","price":72.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/77d5167acd889de63d06a0523c15cc13.jpg?v=1788364357","url":"https:\/\/voomisupply.com\/products\/cleveland-c33071-square-end-mill-5-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
