Built with a steel toolholder body, it accepts RA216-1302 style inserts secured by screw clamping, providing repeatable positioning and secure insert retention under demanding cutting loads. The straight shank mounts directly into standard collet chucks or side-lock holders. With a 0.5 inch cutting diameter, a maximum depth of cut of 0.444 inches, and support for up to 21,000 RPM, this holder suits high-speed finishing and semi-finishing applications on CNC machining centers.\u003c\/p\u003e\n\u003cp\u003eThe 5739117 is intended for CNC milling operations in job shops, production machining environments, and tool rooms running steel workpieces. The CoroMill 216 series is a common platform in both light and medium-duty milling tasks where ball nose geometry is required for contoured surfaces, die cavities, and complex part profiles. Its 7.874 inch overall length allows reach into deeper pockets while the 1.2402 inch head length keeps the insert zone compact. Two ball nose inserts provide balanced cutting action suitable for both climb and conventional milling passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.5 inch cutting diameter with 0.444 inch maximum depth of cut for controlled step-down passes\u003c\/li\u003e\n  \u003cli\u003eAccepts RA216-1302 inserts via screw clamping for secure, repeatable insert seating\u003c\/li\u003e\n  \u003cli\u003eStraight shank, Weldon flat-free design for standard collet and side-lock compatibility\u003c\/li\u003e\n  \u003cli\u003eRated to 21,000 RPM for high-speed CNC finishing operations\u003c\/li\u003e\n  \u003cli\u003e7.874 inch overall length with 6.311 inch projection for extended reach applications\u003c\/li\u003e\n  \u003cli\u003e2-flute, 2-insert ball nose configuration for balanced cutting forces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with RA216-1302 style inserts.

Power down and lock out the machine spindle before inserting or removing the toolholder or changing inserts. Torque the insert clamping screw using the appropriate Torx or hex key as specified in the insert manufacturer documentation — do not over-tighten. Verify runout with a dial indicator after clamping and before initiating any cutting cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.444 inches (11.28 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7.874 inches (200.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.2402 inches (31.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 6.311 inches (160.30 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 21,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Ball Nose Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: RA216-1302\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: RA216..Oxx\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroMill 216\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeldon Flat\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.82 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5739117\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748507353394,"sku":"5739117","price":632.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8fa219d4a919670c6315dcff0070b288_d8bcdbee-4f9b-4aef-b722-d086237341c3.jpg?v=1788894601","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5739117-ball-nose-end-mill-0-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
