Built from high speed steel (HSS) with a titanium carbonitride (TiCN) coating, it delivers improved wear resistance and surface hardness compared to uncoated HSS tooling. The cutting diameter is 0.4375 inches (7\/16 inch), with a 1-inch length of cut and a 0.500-inch straight-cylindrical shank that also accepts a Weldon flat drive. Overall length is 4.5 inches. The 30-degree helix spiral flute geometry promotes chip evacuation and reduces heat buildup during the cut. This tool is installed and changed by machinists and CNC operators working on milling machines and machining centers.\u003c\/p\u003e\u003cp\u003eThe C33120 is suited for slotting, profiling, and plunge-capable operations in cast iron, non-ferrous metals, and steel. The centercutting geometry allows direct plunge entry without a pilot hole. The Series HD-4C designation indicates a heavy-duty four-flute configuration optimized for rigidity and finish quality in these material classes. It is appropriate for both conventional and climb milling strategies when rigidity and fixturing are sufficient.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and extends tool life versus bare HSS\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003eDouble-end construction provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes efficient chip evacuation in steel and cast iron\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute orientation compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with Weldon flat accommodates standard end mill holders and set-screw holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in milling machines and machining centers accepting a 1\/2-inch shank end mill holder.

Secure the shank in a properly sized end mill holder, torquing the set screw against the Weldon flat per the toolholder manufacturer specification. Inspect the collet or holder bore for chips or damage before seating the tool. Confirm runout with a dial indicator before beginning a new operation when tight tolerances are required.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.4375 inches (7\/16 inch)\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches (1\/2 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 (HSS)\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\u003eDouble End\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: HD-4C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: C33120\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51690471260466,"sku":"C33120","price":76.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d0215e1c7eab3f3a5bb3105fcf22676a.jpg?v=1788270388","url":"https:\/\/voomisupply.com\/products\/cleveland-c33120-square-end-mill-7-16-in-4-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
