Built on the Kenclamp series platform, it accepts CN.. style inserts with a 1\/2-inch inscribed circle and uses a clamp-style insert holding method with a negative rake angle of 5 degrees. The shank diameter is 2-1\/2 inches with an overall length of 16 inches, making it suited for deep bore applications requiring rigidity and reach. Through-coolant capability is standard via a 1\/4-18 NPT coolant hole, supporting chip evacuation and thermal control at the cutting edge. The bar is constructed of steel and carries a -5 degree lead angle.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in production and job-shop environments on CNC lathes and boring mills where precise internal diameter finishing or roughing is required. With a minimum bore diameter of 3.03 inches, it is appropriate for medium-to-large bore work on steel, cast iron, and similar workpiece materials. The through-coolant feature makes it especially useful in high-speed operations or when machining difficult-to-cut alloys where heat and chip management are critical. Licensed machinists and CNC operators working in industrial manufacturing, toolroom, or maintenance-repair-overhaul settings are the primary users of this toolholder.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 3.03 inches for medium-to-large internal turning applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 1\/4-18 NPT coolant hole thread for improved chip control and tool life\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method provides secure seating under heavy cutting loads\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry at 5 degrees suits interrupted cuts and hard materials\u003c\/li\u003e\n\u003cli\u003eCenter to cutting edge dimension of 1.531 inches for predictable offset setup\u003c\/li\u003e\n\u003cli\u003eSteel construction for rigidity and vibration resistance in deep-reach boring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CN.. style indexable inserts with a 1\/2-inch inscribed circle and 3\/16-inch insert thickness, following the A-DCLN-KC toolholder style designation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before mounting or removing the boring bar. Confirm shank bore fit and torque set screws or clamp hardware per the machine tool manufacturer specifications. Connect the coolant line to the 1\/4-18 NPT port only after verifying thread compatibility with the coolant delivery system to avoid leaks during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 3.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-DCLN-KC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenclamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CN..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 1.531 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Hole Thread Size\u003c\/strong\u003e: 1\/4-18 NPT\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: 22.13 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2408526\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743636128050,"sku":"2408526","price":899.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f06e599dadaf0c633343c77c9516468.jpg?v=1788848734","url":"https:\/\/voomisupply.com\/products\/kennametal-2408526-indexable-boring-bar-3-03in-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
