Part of the CoroDrill 870 series, it accepts 870-2390-23-PM style inserts seated at insert seat size 23, allowing fast tip changes without removing the tool body from the spindle. The drill body is constructed from steel with a straight-cylindrical shank and features through-coolant capability to clear chips and manage heat at the cutting zone. It covers a drill diameter range of 23.00 to 23.99 mm (0.9055 to 0.9445 inches) with a maximum drill depth of 123.57 mm (4.865 inches), representing a 5xD depth-to-diameter ratio. Overall length is 205 mm (8.071 inches). This tool is intended for use by machinists and CNC operators in production machining environments.\u003c\/p\u003e\n\u003cp\u003eThe 6239457 drill body is suited for through-hole and blind-hole operations in ferrous and non-ferrous materials where consistent diameter control across medium-depth bores is required. The 870 LX-5 toolholder style integrates with compatible CNC machining centers and turning centers running through-coolant systems. The replaceable-tip design reduces tooling downtime by allowing insert swaps at the machine without full tool disassembly, making it practical for high-volume production runs and job shop environments where changeover speed matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip design accepts 870-2390-23-PM inserts at insert seat size 23 for fast in-machine tip changes\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability directs coolant to the cutting edge for chip evacuation and thermal control\u003c\/li\u003e\n  \u003cli\u003e5xD depth-to-diameter ratio supports drilling to 123.57 mm (4.865 inches) maximum depth\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank in 870 LX-5 toolholder style for secure spindle retention\u003c\/li\u003e\n  \u003cli\u003eSteel body construction provides rigidity across the 205 mm (8.071 inches) overall length\u003c\/li\u003e\n  \u003cli\u003eFlute length of 145.39 mm (5.724 inches) supports chip flow throughout the full depth range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible insert style is 870-2390-23-PM at insert seat size 23.

Ensure the machine spindle is fully stopped and the tool turret or carousel is safely indexed before inserting or removing the drill body. Confirm through-coolant passages are clear and coolant pressure is within the machine specification before operation. Follow the insert manufacturer torque guidance when seating the replaceable tip to avoid seat damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 23.00 mm (0.9055 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 23.99 mm (0.9445 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 123.57 mm (4.865 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth-to-Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 205.00 mm (8.071 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 145.39 mm (5.724 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 127.00 mm (5.000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 56.00 mm (2.205 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: 870 LX-5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: 870-2390-23-PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 23\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroDrill 870\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThrough Coolant\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\u003ePackage Weight\u003c\/strong\u003e: 1.33 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 8.66 inches length x 1.97 inches width x 1.97 inches height\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291502\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: 6239457\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51747682976050,"sku":"6239457","price":1097.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c306353a2ba425d2a47ec9c4224d6df9_daed546b-0673-4a6b-9f96-b59ba202dfc6.jpg?v=1788884482","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6239457-replaceable-tip-drill-23-23-99mm","provider":"Voomi Supply","version":"1.0","type":"link"}
