Built from high speed steel with a titanium nitride (TiN) finish, it offers improved wear resistance over uncoated HSS tooling. The 7\/16-inch cutting diameter pairs with a 2-3\/4-inch length of cut, making it well suited for deep-slot and deep-shoulder work where standard-length end mills fall short. A 30-degree helix angle and four spiral flutes promote efficient chip evacuation and a smooth cutting action. The 3\/8-inch straight-cylindrical shank with Weldon flat accepts standard side-lock toolholders. Centercutting geometry allows plunge entry. Overall length is 4-1\/2 inches. Licensed machinists and tool-and-die professionals are the primary installers of this tooling.\u003c\/p\u003e\u003cp\u003eThe C33446 is rated for cutting cast iron, non-ferrous metals, and steel, covering the three workpiece material categories most commonly encountered in job shop and production machining environments. The extra-long length of cut — beginning at 2.0 inches and extending to 2-3\/4 inches on this part — handles deep pocket milling, long-reach profiling, and cavity work where a standard end mill cannot reach the full depth of cut. Right-hand cut and right-hand flute geometry is consistent with conventional CNC machining center spindle rotation, requiring no special programming offsets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16-inch cutting diameter with 2-3\/4-inch length of cut for deep-reach milling\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with TiN finish for extended tool life on ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eFour spiral flutes at a 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e3\/8-inch straight-cylindrical shank with Weldon flat for positive side-lock holding\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute — compatible with standard CNC and manual milling spindles\u003c\/li\u003e\n\u003cli\u003eSeries HG-4C extra-long classification for deep-pocket and long-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for primary workpiece materials cast iron, non-ferrous metals, and steel.

De-energize and lock out the machine spindle before changing tooling. Seat the Weldon flat against the set screw in the toolholder to prevent axial pullout under heavy cuts. Verify runout with a dial indicator after installation; excessive runout accelerates flute wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-3\/4 inches (2.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 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\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\u003eEnd Mill Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\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: C33446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51748043948338,"sku":"C33446","price":92.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/28e7a3a50299e03e7421add97284ded1_25cace3f-24bf-4aa9-9ff8-67b4c0070b69.jpg?v=1788888401","url":"https:\/\/voomisupply.com\/products\/cleveland-c33446-square-end-mill-7-16-in-4-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
