It features a TiAlN2 coating applied via PVD process, providing heat and wear resistance for demanding drilling operations in steel and cast materials. The insert carries an 8.9 mm (0.3504 inches) inscribed circle, a thickness of 0.1181 inches, and a 0.5 mm corner radius. The square shape and GM chipbreaker geometry are engineered to control chip formation and reduce cutting forces during through-hole and blind-hole drilling. This insert is installed by machining professionals and CNC operators in metalworking and manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in 880-series indexable drill bodies running right-hand cutting direction. It is suited for production drilling applications in shop environments where consistent hole quality and tool life are priorities. The GM chipbreaker designation targets general-purpose machining in a range of workpiece materials. The mounting hole diameter is 3.2 mm (0.1260 inches), which aligns with the standard 880-series insert pocket fastening system. Typical applications include drilling operations on machining centers and CNC lathes across both job shop and high-volume production settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with manufacturer grade 4344 for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003eTiAlN2 PVD coating for elevated temperature performance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eGM chipbreaker geometry designed for general-purpose drilling with controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 0.5 mm corner radius for consistent cutting edge geometry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction with 8.9 mm inscribed circle for use in standard 880-series drill bodies\u003c\/li\u003e\n  \u003cli\u003eInsert size designation 050305 for precise pocket fitment verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SANDVIK COROMANT 880-series indexable drill bodies requiring a square solid carbide insert with an 8.9 mm inscribed circle and 3.2 mm mounting hole diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the correct torx or hex key to secure the insert fastening screw to the drill body pocket without over-torquing. Inspect the insert pocket seating surface and fastening screw for wear or debris before installing a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 880\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4344\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: GM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 8.90 mm (0.3504 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.50 mm (0.0197 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1181 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 3.20 mm (0.1260 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 050305\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 6770738\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752382890290,"sku":"6770738","price":354.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f60907eee87d6f40f36dbbc9e499611b_0d382a1f-de3b-48c8-98da-06145c8e661a.jpg?v=1788927842","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6770738-indexable-drill-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
