It accepts seven R300-1340 screw-lock inserts and delivers a maximum depth of cut of 0.248 inches (6.30 mm). The cutter style is RA300 with a right-hand cutting direction and through-coolant capability, making it well suited for demanding material removal on ferrous and non-ferrous workpieces. With a nominal cutting diameter of 2.5 inches and a maximum cutting diameter of 3.0 inches, this body handles moderate to large facing and profiling passes. The 1-inch arbor hole provides a solid, repeatable mount on standard horizontal or vertical spindle setups. Installation and operation are handled by trained machinists and CNC tooling specialists.\u003c\/p\u003e\u003cp\u003eThis copy face mill is built for use in production and job-shop environments where contouring, ramping, and copy milling operations are required. The CoroMill 300 platform is widely used in general engineering applications involving steel, cast iron, and aluminum alloy components. The through-coolant design supports extended insert life in continuous or interrupted cutting conditions. The screw-insert holding method ensures positive insert location and fast changeovers, minimizing machine downtime during insert indexing.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAccepts seven R300-1340 indexable inserts secured by screw clamping for positive, repeatable seating\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.248 inches (6.30 mm) supports productive copy and face milling passes\u003c\/li\u003e\n\u003cli\u003eThrough-coolant ports direct cutting fluid to the insert edges for improved chip evacuation and thermal control\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003e1-inch arbor hole with 0.3838-inch keyway width for secure, torque-resistant mounting\u003c\/li\u003e\n\u003cli\u003eCoroMill 300 series ISO designation RA300-076R25-13H for precise catalog cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible insert size code is R300-1340.

Before mounting or indexing inserts, ensure the machine spindle is fully stopped, locked out, and all energy is isolated per applicable OSHA lockout\/tagout procedures. Verify the arbor and keyway are clean and free of burrs before seating the body. Use the manufacturer-specified torque driver for insert screws to avoid over-tightening or stripping the screw threads.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Cutting Diameter\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.248 inches (6.30 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Diameter\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeyway Width\u003c\/strong\u003e: 0.3838 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Height\u003c\/strong\u003e: 1.9685 inches (50.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCounterbore Diameter\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: R300-1340\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5118 inches (13.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Style\u003c\/strong\u003e: RA300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroMill 300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: RA300-076R25-13H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.47 pounds\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: 5739459\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744594526514,"sku":"5739459","price":1316.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50b1208129539934716bf7fea1fbc82f.jpg?v=1788858772","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5739459-indexable-copy-face-mill-coromill-300","provider":"Voomi Supply","version":"1.0","type":"link"}
