Built on a steel shank measuring 1-1\/2 inches in diameter and 14 inches in overall length, this bar maintains a minimum bore diameter of 50.8 mm (2.0000 inches). It accepts DN.. style inserts secured by a clamp-style insert holding method and features a -17.5 degree lead angle with an 8.5 degree negative rake. Through-coolant delivery is supported via a 1\/4-18 NPT coolant hole, making it suited for deep-bore applications where heat and chip evacuation are critical concerns. The Series is Kenclamp.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for machinists and tool-room technicians working in production or job-shop environments. It is designed for left-hand boring applications where the tool feeds in the opposite direction of a standard right-hand holder. Common use cases include finish boring of housings, bearing bores, and hydraulic cylinder bores in both ferrous and non-ferrous materials. Through-coolant capability makes it particularly effective in deep-bore or high-speed cutting conditions where conventional flood coolant cannot adequately reach the cutting zone.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLeft-hand toolholder orientation in the A-DDQN-KC style\u003c\/li\u003e\n\u003cli\u003eThrough-coolant delivery via 1\/4-18 NPT threaded coolant port\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method with negative rake for controlled cutting forces\u003c\/li\u003e\n\u003cli\u003e50.8 mm (2.0000 inch) minimum bore diameter for medium-to-large bore applications\u003c\/li\u003e\n\u003cli\u003e14 inch overall length with 1-1\/2 inch steel shank for rigidity in extended-reach setups\u003c\/li\u003e\n\u003cli\u003eCompatible with DN.. insert geometry with 1\/2 inch inscribed circle and 3\/16 inch insert thickness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with DN.. style inserts featuring a 1\/2 inch inscribed circle and 3\/16 inch thickness, as specified for the A-DDQN-KC toolholder style.

Ensure the shank is properly seated and clamped in the turret or boring head to the tool manufacturer's recommended seating depth before initiating a cut. Connect the through-coolant supply line to the 1\/4-18 NPT port using compatible fittings and verify coolant flow before engaging the cut. Inspect insert seating and clamp torque at each insert change to prevent insert movement during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 50.80 mm (2.0000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-DDQN-KC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14 inches (355.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-1\/2 inches (38.10 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: DN..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\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: 8.50 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -17.5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 1.1250 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\u003eSeries\u003c\/strong\u003e: Kenclamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.971 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: 2408548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738461765938,"sku":"2408548","price":830.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e78044cbbc1081e5d5ac1ea04c80e71.jpg?v=1788799838","url":"https:\/\/voomisupply.com\/products\/kennametal-2408548-indexable-boring-bar-left-hand-50-8mm","provider":"Voomi Supply","version":"1.0","type":"link"}
