Built on the CoroDrill 880 platform, this drill body accepts two indexable inserts and achieves a maximum drill depth of 3.4311 inches at a 4xD depth-to-diameter ratio. The 21mm (0.8898 inch) cutting diameter and 25mm (0.9843 inch) straight cylindrical shank make it compatible with standard toolholder systems found on CNC machining centers and lathes. The steel body is engineered for rigidity under the high radial and axial forces generated during indexable drilling. Coolant-through capability supports chip evacuation and insert life in demanding materials.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for production drilling in ferrous and non-ferrous materials on CNC turning centers and vertical or horizontal machining centers. It is typically applied in automotive, aerospace, energy, and general engineering environments where repeatable hole quality and rapid insert changeout are required. The right-hand cutting direction and straight shank configuration make it straightforward to set up in collet chucks, hydraulic chucks, or Weldon-flat holders sized for 25mm shanks. Machinists and CNC programmers working in job shop and production environments will find the 4xD ratio suitable for through-holes and blind holes in a standard depth range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e21mm (0.8898 inch) maximum drill diameter with 4xD depth-to-diameter ratio\u003c\/li\u003e\n  \u003cli\u003eMaximum drill depth of 3.4311 inches within the 3.0000 to 4.0000 inch depth range class\u003c\/li\u003e\n  \u003cli\u003eAccepts two CoroDrill 880..L-04 series indexable inserts for fast edge changes without removing the body\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design promotes chip evacuation and extends insert life in deep-hole applications\u003c\/li\u003e\n  \u003cli\u003e25mm straight cylindrical shank fits standard CNC toolholders and reduces setup time\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction; steel body construction provides rigidity under high drilling forces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CoroDrill 880..L-04 series indexable inserts (insert size 2.80mm \/ 0.1102 inch).

Ensure the machine spindle is fully stopped and the toolchanger is disabled before mounting or removing the drill body. Confirm the toolholder bore is clean and free of chips before seating the 25mm shank, and torque the clamping screws to the toolholder specification. Follow the machine tool builder and SANDVIK COROMANT application guidelines for starting feed and speed parameters when running a new insert grade or workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 21mm (0.8898 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 3.4311 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 4xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth Range Class\u003c\/strong\u003e: 3.0000 to 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 25mm (0.9843 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 56mm (2.2047 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 99.20mm (3.9055 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 87.00mm (3.4252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2.80mm (0.1102 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Drill Style\u003c\/strong\u003e: 880..L-04\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.93 pounds\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: 5765385\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51743918489906,"sku":"5765385","price":983.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d9c96f7b9f9cfde4506ebe5bd785b496.jpg?v=1788851262","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5765385-indexable-insert-drill-21mm","provider":"Voomi Supply","version":"1.0","type":"link"}
