It accepts 870-1290-11-PM style inserts at insert seat size 11, allowing fast tip changes without removing the body from the spindle. The drill covers a diameter range of 12.5 to 12.99 mm (0.4921 to 0.5114 inches) with a maximum drill depth of 40.97 mm (1.613 inches), corresponding to a 3xD depth-to-diameter ratio. Overall length is 104 mm (4.0945 inches). Through-coolant capability is built in, supporting high-pressure coolant delivery directly to the cutting zone for improved chip evacuation and tool life in production environments.\u003c\/p\u003e\n\u003cp\u003eThis drill body is suited for CNC machining centers and turning centers in industrial production environments. It is typically installed by machinists and tooling setup technicians in shops running ferrous and non-ferrous materials where consistent, repeatable hole tolerances are required. The straight-cylindrical shank style and 870 LX-3 toolholder compatibility make it straightforward to mount in standard collet chucks or dedicated CoroDrill 870 toolholders. It is appropriate for medium-volume to high-volume production runs where insert indexability and coolant-through performance are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReplaceable-tip design accepts 870-1290-11-PM inserts for fast, on-machine tip changes\u003c\/li\u003e\n  \u003cli\u003eDiameter range 12.5 to 12.99 mm (0.4921 to 0.5114 inches) with 3xD depth ratio\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant construction for direct high-pressure coolant delivery to the cutting edge\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank compatible with 870 LX-3 toolholder style\u003c\/li\u003e\n  \u003cli\u003eSteel body construction for rigidity and vibration damping during drilling cycles\u003c\/li\u003e\n  \u003cli\u003eFlute length of 54.02 mm (2.1268 inches) supports full chip clearance at maximum depth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with 870-1290-11-PM style replaceable-tip inserts at insert seat size 11.

Ensure the machine spindle is fully stopped and the tool is de-energized before mounting or changing inserts. Use the appropriate torque wrench and insert screws specified for the CoroDrill 870 system when seating replaceable tips. Verify through-coolant connections are clear and properly pressurized before initiating a drilling cycle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Drill Diameter\u003c\/strong\u003e: 12.50 mm (0.4921 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 12.99 mm (0.5114 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 40.97 mm (1.613 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDrill Depth by Diameter Ratio\u003c\/strong\u003e: 3xD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 104 mm (4.0945 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 54.02 mm (2.1268 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 43 mm (1.6929 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 48 mm (1.8898 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-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: 870-1290-11-PM\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\u003eSeries\u003c\/strong\u003e: CoroDrill 870\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.34 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.04 inches (L) x 1.42 inches (W) x 1.42 inches (H)\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: 6035644\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51738476871986,"sku":"6035644","price":548.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1546e1db7a460bc950eeea15b5e87f3_d18f20f7-4903-4a54-9a53-44c957603142.jpg?v=1788800043","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6035644-replaceable-tip-drill-12-5-12-99mm","provider":"Voomi Supply","version":"1.0","type":"link"}
