Carrying the 4344 manufacturer grade and a TiAlN2 PVD coating, it delivers thermal and wear resistance suited to demanding drilling operations in steel, cast iron, and similar workpiece materials. The square insert shape uses a GR chipbreaker geometry to control chip formation and evacuation at the cutting zone. With a 6.00 mm (0.2362 inch) inscribed circle and a 0.60 mm (0.0236 inch) corner radius, this insert is sized for precision hole-making applications where consistent dimensional results are required. Installation is handled by machining professionals in job shop, production, or maintenance environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended for right-hand cutting direction and fits 880-style indexable drill bodies that accept the 030306 insert size. It is commonly used in CNC machining centers, drilling cells, and manual or CNC lathes configured for drilling operations. Typical applications include through-hole and blind-hole drilling in ferrous and non-ferrous materials where a PVD-coated solid carbide insert is specified. The GR chipbreaker suits general-purpose cutting conditions at moderate to high feed rates.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with TiAlN2 PVD coating for heat and wear resistance\u003c\/li\u003e\n\u003cli\u003eGR chipbreaker geometry for effective chip control in drilling applications\u003c\/li\u003e\n\u003cli\u003e6.00 mm inscribed circle with 0.60 mm corner radius for precise fitment and edge integrity\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction; square insert shape (030306 insert size)\u003c\/li\u003e\n\u003cli\u003eHole diameter of 2.50 mm (0.0984 inch) for secure clamping in 880-series drill bodies\u003c\/li\u003e\n\u003cli\u003eInsert thickness of 0.1024 inches for dimensional consistency at the seat\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for 880-series indexable drill bodies accepting the 030306 square insert size in right-hand cutting configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInsert indexing and replacement should be performed by a qualified machinist or tooling technician with the machine fully de-energized and the spindle locked. Use the appropriate Torx or insert-clamping driver specified by the drill body manufacturer to achieve proper seating torque without over-driving the clamping screw. Inspect the insert pocket and seating surface for debris or damage before installing a new insert. Do not use damaged or improperly seated inserts, as this can result in insert fracture or loss of dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: GR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 030306\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 6.00 mm (0.2362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.60 mm (0.0236 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1024 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 2.50 mm (0.0984 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.57 inches W x 0.53 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 6770731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51751044710706,"sku":"6770731","price":318.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f60907eee87d6f40f36dbbc9e499611b_d4d6d845-ef29-482b-ae6e-a53c8425f28b.jpg?v=1788921361","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6770731-indexable-drill-insert-880gr","provider":"Voomi Supply","version":"1.0","type":"link"}
