With a 3\/16-inch (0.1875-inch) cutting diameter and a 9\/32-inch (0.2813-inch) length of cut, this stub-length tool is suited for slotting, profiling, and peripheral milling where rigidity and close-tolerance work are required. The 30-degree helix angle promotes efficient chip evacuation, and the centercutting geometry allows direct plunge entry into the workpiece. Machinists and tool-and-die professionals in job shops and production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill fits applications requiring a 3\/8-inch straight cylindrical or Weldon flat shank. The stub-length profile provides added rigidity for interrupted cuts and short-reach operations in cast iron, aluminum and other non-ferrous alloys, and steel workpieces. The spiral, right-hand cut and right-hand flute configuration is compatible with standard vertical milling machines and machining centers running conventional right-hand spindle rotation. Series HD-2 tools are intended for general-purpose material removal where an uncoated HSS cutter is appropriate.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-end design extends usable tool life between sharpenings\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows plunge milling without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eUncoated HSS construction suitable for re-sharpening in-house\u003c\/li\u003e\n  \u003cli\u003eStub-length body (2-3\/4 inches OAL) maximizes rigidity and minimizes deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute — compatible with standard spindle rotation on most milling equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for primary workpiece materials including cast iron (K), non-ferrous metals (N), and steel (P).

Secure the shank fully in a collet or end mill holder, confirming that the Weldon flat (if present) is engaged by the set screw before starting the spindle. Verify spindle direction is set to right-hand rotation before engaging the cut. Never exceed the recommended depth of cut for the 9\/32-inch length-of-cut range without confirming workpiece fixturing rigidity.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eLength of Cut Range\u003c\/strong\u003e: 0.2000 - 0.3000 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: 2-3\/4 inches\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: Uncoated\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical \/ Weldon Flat\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: Stub\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Double End\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\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: C42099\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51703117578546,"sku":"C42099","price":54.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a053cb0709f82bcd22b8875cda3cdb7.jpg?v=1788414897","url":"https:\/\/voomisupply.com\/products\/cleveland-c42099-square-end-mill-3-16-in-2-flute-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
