Part of the CoroMill 390 series, this cutter accepts five R390-17.. style inserts and delivers a 90-degree lead angle with a positive rake geometry. It features a right-hand cutting direction and a maximum cutting diameter of 2.5 inches (63.50 mm). The arbor hole diameter measures 0.75 inches (19.05 mm), and the maximum depth of cut reaches 15.70 mm (0.6181 inches). Inserts are secured via clamp and screw, providing reliable holding during demanding cuts. The body is constructed from steel and is intended for installation by machining and toolroom professionals.\u003c\/p\u003e\u003cp\u003eThis face mill is suited for square-shoulder milling operations in both production machining and job-shop environments. Its close-pitch insert configuration with five flutes supports higher feed rates and efficient material removal. Typical applications include face milling, shoulder milling, and slot milling on ferrous and non-ferrous workpiece materials. The CoroMill 390 platform is a widely used series in CNC machining centers where square-shoulder accuracy and insert versatility are required. The cutter does not feature through-coolant capability, so external coolant delivery should be planned accordingly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2.5-inch (63.50 mm) maximum cutting diameter for medium-range face milling operations\u003c\/li\u003e\n\u003cli\u003e90-degree lead angle for true square-shoulder profiles\u003c\/li\u003e\n\u003cli\u003eAccepts 5 R390-17.. indexable inserts in a close-pitch arrangement\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry reduces cutting forces on the workpiece\u003c\/li\u003e\n\u003cli\u003eClamp and screw insert holding method for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction, steel body construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with R390-17.. series indexable inserts.

Ensure the machine spindle and arbor are fully powered down and locked out before mounting or removing the cutter body. Verify that insert pockets are clean and free of debris before seating R390-17.. inserts, and confirm all clamp screws are torqued according to the insert manufacturer's documentation. External coolant lines should be positioned to target the cutting zone, as this cutter does not support coolant-through delivery.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 15.70 mm (0.6181 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.575 inches (40.01 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Body Diameter\u003c\/strong\u003e: 2.437 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 0.3839 inches (9.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R390-17..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: RA390\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Type\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroMill 390\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SANDVIK COROMANT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5739803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755110367538,"sku":"5739803","price":1080.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9435f14fbdfcc7308e73e0f4727a90d_8337a1ea-e6f7-4f4b-b6a3-cd974861e9ba.jpg?v=1788951239","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5739803-square-shoulder-face-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
