Carrying the 4344 manufacturer grade with a TiAlN2 PVD coating, this insert is built to handle demanding hole-making operations in steel, cast iron, and similar workpiece materials. The square insert shape with an LM chipbreaker geometry promotes efficient chip formation and evacuation in through-hole and blind-hole drilling applications. Key dimensional specs include a 12.65 mm (0.4980 inch) inscribed circle, a 1.00 mm (0.0394 inch) corner radius, and a thickness of 0.1575 inches. Right-hand cutting direction is standard.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metalworking and machining environments where precision hole quality and tool longevity are priorities. It seats in 880-series indexable drill bodies as a peripheral or center insert replacement, depending on body configuration and insert position. Typical users include CNC machinists, toolroom technicians, and production floor operators running turning centers, machining centers, or dedicated drilling equipment. The LM chipbreaker is suited to a range of feed and speed conditions common in general-purpose drilling of ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN2 PVD coating for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003e880LM chipbreaker geometry promotes controlled chip formation during drilling\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 1.00 mm corner radius — insert size 070410\u003c\/li\u003e\n  \u003cli\u003e12.65 mm inscribed circle (0.4980 inches) for accurate seating in 880-series drill bodies\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; 4.00 mm mounting hole diameter\u003c\/li\u003e\n  \u003cli\u003eSold individually; minimum order quantity is 10 units\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for 880-series indexable drill bodies that accept square inserts with a 12.65 mm inscribed circle and 4.00 mm mounting hole.

Always de-energize and lock out the machine spindle before changing inserts. Use the correct Torx or hex key specified for the clamping screw — do not substitute drivers that may damage the screw head or insert pocket. Inspect the insert pocket and locating surfaces for chips or debris before seating a new insert to ensure proper contact and runout.\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\u003eChipbreaker\u003c\/strong\u003e: LM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\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: 12.65 mm (0.4980 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 070410\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\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\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: 6770749\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731777126706,"sku":"6770749","price":419.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f60907eee87d6f40f36dbbc9e499611b_8562e9b9-3c72-4206-a4d7-2c3c861614e7.jpg?v=1788734829","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6770749-indexable-drill-insert-880lm","provider":"Voomi Supply","version":"1.0","type":"link"}
