Manufactured from high speed steel with a titanium carbonitride (TiCN) finish, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The cutter measures 0.1875 inches (3\/16 inch) in diameter with a 9\/32-inch length of cut and a 3\/8-inch straight-cylindrical shank compatible with standard collets and Weldon flat holders. A 30-degree helix angle promotes efficient chip evacuation. Licensed machinists and tool-and-die professionals are the primary installers of this tooling in manual and CNC milling operations.\u003c\/p\u003e\u003cp\u003eThe C39051 is suited for milling cast iron, non-ferrous metals, and steel in both production and maintenance shop environments. Its stub-length profile provides added rigidity in tight setups where overhang must be minimized. The double-end design allows the operator to index to a fresh cutting end when one end dulls, extending usable tool life. Right-hand cut and right-hand flute geometry follows the most common milling machine spindle convention, making this a straightforward drop-in for general-purpose slotting, profiling, and plunge-capable operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiCN coating increases surface hardness and reduces tool wear on ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eDouble-end design provides two usable cutting ends per tool\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes chip evacuation and smooth cutting action\u003c\/li\u003e\n\u003cli\u003eStub-length profile (9\/32-inch LOC) maximizes rigidity in close-quarter setups\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with Weldon flat accommodates both collet chucks and set-screw holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard milling machine spindles accepting a 3\/8-inch straight shank.

Power down and lock out the milling machine spindle before mounting or removing the cutter. Ensure the shank is fully seated and the collet or Weldon flat set screw is tightened to the tool holder manufacturer's specification before operation. Inspect the cutting edges for chips or wear before each use; do not operate a visibly damaged end mill.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/32 inch (0.2813 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 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: 2\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\u003eCoating\u003c\/strong\u003e: TiCN\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\u003eDouble End\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HD-2\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: C39051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51694349877554,"sku":"C39051","price":63.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5aa2f8089ecf1ece881e0f112b94d519.jpg?v=1788323454","url":"https:\/\/voomisupply.com\/products\/cleveland-c39051-square-end-mill-3-16-in-2-flute-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
