The tool accepts 870-2590-25-PM inserts at insert seat size 25, covering a drill diameter range of 25 to 25.99 mm (0.9843 to 1.0232 inches). Maximum drill depth reaches 133.88 mm (5.2709 inches), representing a 5xD depth-to-diameter ratio. Overall length is 223 mm (8.7795 inches). The steel body features a straight-cylindrical shank and through-coolant capability to support chip evacuation and tool life at depth. Machinists and CNC operators install this tool in machining centers and lathes equipped for high-pressure coolant delivery.\u003c\/p\u003e\n\u003cp\u003eThe 6239990 is suited for production drilling in medium to large component manufacturing where consistent hole geometry and repeatable insert indexing are required. The replaceable-tip design reduces downtime by allowing tip changes at the machine without removing the body from the spindle. The 870 LX-5 toolholder style designation applies to this body. Flute length is 159.09 mm (6.2634 inches), and shank length is 60 mm (2.3622 inches), providing adequate clearance in typical workholding setups. Through-coolant supports drilling into harder materials and deeper holes where flood coolant alone is insufficient.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip system using 870-2590-25-PM inserts, insert seat size 25\u003c\/li\u003e\n  \u003cli\u003e5xD depth-to-diameter ratio with maximum drill depth of 133.88 mm (5.2709 inches)\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant channel for effective chip evacuation and heat management at depth\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank for direct spindle or toolholder mounting\u003c\/li\u003e\n  \u003cli\u003eSteel body construction, CoroDrill 870 series, toolholder style 870 LX-5\u003c\/li\u003e\n  \u003cli\u003eOverall length of 223 mm (8.7795 inches) with flute length of 159.09 mm (6.2634 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible insert style is 870-2590-25-PM at insert seat size 25.

The machine spindle must be fully stopped and the tool-change cycle completed before handling the drill body or indexing inserts. Verify that the machine spindle interface and coolant connection are compatible with the straight-cylindrical shank and through-coolant port before mounting. Follow the toolholder manufacturer torque guidelines for clamping the insert 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: 25 mm (0.9843 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 25.99 mm (1.0232 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 133.88 mm (5.2709 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 5xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 223 mm (8.7795 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 159.09 mm (6.2634 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 137 mm (5.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 60 mm (2.3622 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: 870-2590-25-PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 25\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\u003eWeight\u003c\/strong\u003e: 2.03 pounds\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: 6239990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731916259634,"sku":"6239990","price":1199.61,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c306353a2ba425d2a47ec9c4224d6df9_3ed370bd-6ba2-4e7e-8c6b-176d2b831d04.jpg?v=1788736548","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6239990-replaceable-tip-drill-25mm-5xd","provider":"Voomi Supply","version":"1.0","type":"link"}
