It features a 0.75-inch milling diameter, a 1.625-inch length of cut, and a 3.75-inch overall length. The spiral flute geometry and 42-degree helix angle promote efficient chip evacuation and smooth cutting action. Designed for right-hand cut and right-hand flute orientation, this centercutting tool can plunge directly into a workpiece, making it versatile for slotting, profiling, and face milling operations. Machinists and tool-and-die professionals working with non-ferrous metals will find this end mill a reliable production choice.\u003c\/p\u003e\n\u003cp\u003eThe C40346 is primarily suited for machining non-ferrous metals, including aluminum, copper, brass, and similar materials. Its straight cylindrical shank with a Weldon flat allows secure seating in standard end mill holders and Weldon-style collet chucks. The regular length designation and 0.75-inch shank diameter make this a practical fit for vertical machining centers, knee mills, and CNC machining cells handling light-to-medium material removal on non-ferrous workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction provides consistent grain structure and improved wear resistance over standard HSS\u003c\/li\u003e\n  \u003cli\u003eTiCN coating reduces friction and extends tool life on non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle promotes efficient chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eWeldon flat on straight cylindrical shank prevents pullout under aggressive feed rates\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute orientation compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 0.75-inch end mill holders, Weldon-style holders, and collet chucks on vertical machining centers and manual knee mills.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the holder and tighten set screws against the Weldon flat to manufacturer torque guidelines for the holder in use. Verify runout with a dial indicator before beginning a production cut, and confirm feed rate and spindle speed are appropriate for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: PM-539R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 42 degrees\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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 Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: C40346\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51714317254962,"sku":"C40346","price":179.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b3a83f8decae4cce3298fc91e4d0d345.jpg?v=1788499392","url":"https:\/\/voomisupply.com\/products\/cleveland-c40346-square-end-mill-3-flute-0-75-in-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
