Built to the DR-4D-N series standard, it accepts two SOMX060304 inserts and delivers a maximum drill depth of 2.84 inches at a 4xD depth-to-diameter ratio. The body is constructed from steel with a 1-inch Weldon flat shank that seats securely in compatible toolholders. Overall length is 6.70 inches. Coolant is delivered through both axial concentric and radial ports, with NPT-threaded coolant entry points at both the shank end and body side to support high-pressure through-coolant systems. This drill is installed and operated by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 3260051 is suited for general-purpose drilling operations on machining centers and CNC lathes where a right-hand cutting, straight-shank indexable drill is required. The 18mm maximum drill diameter and 4xD depth ratio make it appropriate for medium-depth hole applications across a range of ferrous and non-ferrous workpiece materials. The Weldon flat shank and 1-inch modular connection size allow positive drive without slippage under typical production feeds and speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4xD drill depth ratio with 2.84 inch maximum drill depth and 2.84 inch flute length\u003c\/li\u003e\n  \u003cli\u003eAccepts two SOMX060304 indexable inserts for fast edge changes without regrinding\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capable with axial concentric and radial coolant delivery ports\u003c\/li\u003e\n  \u003cli\u003e1-inch Weldon flat shank provides positive torque drive and accurate seating\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard spindle rotation on CNC machining centers\u003c\/li\u003e\n  \u003cli\u003eSteel body construction in the DR-4D-N series with 6.70 inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible insert style is SOMX, compatible insert size code is 060304 (SOMX060304).

Seat the Weldon flat shank fully into the toolholder and confirm setscrew engagement against the flat before operation. Verify coolant line connections at both the shank end and body side ports before running coolant-through cycles. Follow the insert manufacturer torque guidelines for the SR 34-508\/L lock screw and inspect insert seating before each production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Diameter\u003c\/strong\u003e: 0.7990 inches (18mm nominal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Drill Depth\u003c\/strong\u003e: 2.84 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\u003eOverall Length\u003c\/strong\u003e: 6.70 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 2.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 3.70 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 3.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1.0 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Weldon Flat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 1.26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollar Diameter\u003c\/strong\u003e: 1.26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Style\u003c\/strong\u003e: SOMX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 060304\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 0.2441 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Lock Screw\u003c\/strong\u003e: SR 34-508\/L\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\u003eCoolant Entry Style\u003c\/strong\u003e: Axial Concentric and Radial\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank End Coolant Hole Thread Size\u003c\/strong\u003e: 3\/8-18 NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Side Coolant Hole Thread Size\u003c\/strong\u003e: 1\/16-27 NPT\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: DR-4D-N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Drilling\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Performance\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModular Connection Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.637 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291503\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3260051\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51751845822770,"sku":"3260051","price":788.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f3fe2ad00709482a74bc61362f1972b.jpg?v=1788924442","url":"https:\/\/voomisupply.com\/products\/iscar-3260051-indexable-insert-drill-18mm-4xd","provider":"Voomi Supply","version":"1.0","type":"link"}
