This insert carries a manufacturer grade designation of 4334 and features a multilayer CVD coating of TiCN, Al2O3, and TiN, which provides thermal resistance and wear protection during demanding hole-making operations. It has a square shape with an 880GR chipbreaker geometry and is configured for right-hand cutting direction. With an inscribed circle of 0.498 inches (12.65 mm) and a corner radius of 0.047 inches (1.20 mm), this insert is suited for precision drilling applications in ferrous and similar workpiece materials. Licensed HVAC technicians and trade machinists handling metal fabrication rely on this type of insert for consistent, repeatable hole quality.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in CNC machining centers, turning centers with live tooling, and dedicated drilling machines where 880-series indexable drill bodies are in service. It is appropriate for production-volume drilling in shop environments requiring tight tolerances. The GR chipbreaker geometry is engineered to manage chip evacuation in through-hole and blind-hole drilling scenarios. The insert size designation is 070412, and it is sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiCN\/Al2O3\/TiN multilayer coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e880GR chipbreaker geometry supports effective chip control in drilling operations\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 0.047 inch (1.20 mm) corner radius for consistent edge engagement\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting configuration matches standard 880-series drill body orientation\u003c\/li\u003e\n  \u003cli\u003eInscribed circle of 0.498 inches (12.65 mm) and insert size 070412 for precise seating\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1575 inches (4.00 mm) for correct mounting in compatible tool bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for use in SANDVIK COROMANT 880-series indexable drill bodies requiring an insert size 070412 square geometry with GR chipbreaker.

Ensure the machine spindle is fully stopped and the tool body is removed from the machine or locked out before handling inserts. Use the manufacturer-specified torx or hex key to remove and reseat the clamping screw, and inspect the insert pocket for wear or debris before seating the new insert. Do not overtighten the clamping screw beyond the tool body manufacturer's recommendation.\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: 4334\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\u003eInscribed Circle\u003c\/strong\u003e: 0.498 inches (12.65 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.047 inches (1.20 mm)\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: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 070412\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiCN\/Al2O3\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0154 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: 6633725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51746700689714,"sku":"6633725","price":420.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e8e1a99bc7e537edfe90c6a3e229efc_cd4e5ad4-ea3c-46f5-aaee-ac6909af69c9.jpg?v=1788872983","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6633725-indexable-drill-insert-880gr-4334","provider":"Voomi Supply","version":"1.0","type":"link"}
