Built from high speed steel with a titanium nitride (TiN) finish, it offers increased surface hardness and wear resistance over uncoated HSS tooling. The cutter measures 11\/16 inch (0.6875 inch) in diameter with a 3\/4 inch straight-cylindrical shank that also features a Weldon flat for positive drive in standard end mill holders. With a 2-1\/4 inch length of cut and 5-1\/4 inch overall length, this is a long-series tool suited for applications requiring extended reach into deep pockets or tall workpiece features.\u003c\/p\u003e\u003cp\u003eThe C39092 is intended for milling operations on cast iron, non-ferrous metals, and steel. Its centercutting geometry allows direct plunge entry without a pre-drilled hole, making it effective for slot milling, pocket roughing, and profile work on vertical machining centers and manual knee mills. The right-hand cut and right-hand spiral flute configuration follows standard conventions for CNC and conventional milling setups. The 30-degree helix angle promotes chip evacuation and smooth cutting action across the supported workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e11\/16 inch (0.6875 inch) cutting diameter with 2-1\/4 inch length of cut for deep slot and pocket work\u003c\/li\u003e\n\u003cli\u003eHigh speed steel construction with TiN coating for improved hardness and tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle supports efficient chip evacuation in cast iron, non-ferrous metals, and steel\u003c\/li\u003e\n\u003cli\u003e3\/4 inch straight-cylindrical shank with Weldon flat for secure clamping in standard holders\u003c\/li\u003e\n\u003cli\u003eLong-series (HG-2) designation provides extended reach versus standard-length equivalents\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for applications requiring a 3\/4 inch shank, 11\/16 inch diameter, 2-flute square end mill in standard end mill holders or Weldon-flat collet chucks.

Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the Weldon flat against the set screw in the holder to prevent tool pull-out under load. Verify runout with a dial indicator after clamping before beginning a cut, and confirm feed and speed parameters are appropriate for the workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 11\/16 inch (0.6875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (2.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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: Titanium Nitride (TiN)\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 with 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: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HG-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: C39092\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51709480927538,"sku":"C39092","price":126.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7143ff21ca9a6d2f785ed8d4c6a7125d.jpg?v=1788457019","url":"https:\/\/voomisupply.com\/products\/cleveland-c39092-square-end-mill-11-16-in-2-flute-hss-tin","provider":"Voomi Supply","version":"1.0","type":"link"}
