Built from high speed steel (HSS) with a titanium carbonitride (TiCN) finish, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The cutter measures 0.75 inches in diameter with a 3-inch length of cut and a 5.25-inch overall length. Three spiral flutes with a 30-degree helix angle promote chip evacuation and smooth cutting action. This is a centercutting design, allowing plunge entry into the workpiece where the application calls for it. It belongs to the HG-3 long series and is suited for general milling, slotting, and profiling work.\u003c\/p\u003e\u003cp\u003eThe C39787 is intended for use in vertical mills, machining centers, and knee mills where a 0.75-inch straight shank with Weldon flat is appropriate. The long flute length makes it well suited for applications requiring deeper cuts or where workpiece geometry limits access with standard-length tooling. Primary workpiece materials include cast iron, non-ferrous metals, and steel, covering a broad range of production and maintenance machining scenarios. Machinists and toolroom professionals working in job shop or manufacturing environments will find this end mill suitable for both conventional and climb milling strategies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh speed steel construction with TiCN coating for added wear resistance\u003c\/li\u003e\n\u003cli\u003eThree spiral flutes at a 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge milling\u003c\/li\u003e\n\u003cli\u003eLong series (HG-3) with 3-inch length of cut for deeper reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration — standard CNC and manual mill orientation\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with Weldon flat for secure tool holding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 0.75-inch end mill holders or Weldon-style set-screw holders.

Ensure the machine spindle and holder are clean and free of debris before seating the shank. Torque set screws on Weldon-style holders to the tool holder manufacturer's specification. Verify spindle direction is set to right-hand rotation before engaging the cut. Confirm appropriate speeds and feeds for the workpiece material and depth of cut before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.25 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\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003eSeries\u003c\/strong\u003e: HG-3\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\u003eLength Type\u003c\/strong\u003e: Long\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: C39787\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CLEVELAND CONTROLS","offers":[{"title":"Default Title","offer_id":51699995705650,"sku":"C39787","price":182.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fc174e5cca3ff4d813b0ac9874ad70d.jpg?v=1788384729","url":"https:\/\/voomisupply.com\/products\/cleveland-c39787-square-end-mill-3-4-in-3-flute-hss-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
