Built to the A-MDUN toolholder style in the Kenloc series, it accepts DN-style inserts held by screw or clamp and cuts with a negative rake angle of 5 degrees. The shank diameter is 1-1\/4 inches (31.75 mm) with an overall length of 14 inches (355.60 mm). The minimum bore diameter is 1.705 inches (43.31 mm), making it suited for moderate to large bore applications. Coolant-through capability is included, with a 1\/4-18 NPT coolant hole thread for directed cutting fluid delivery. Installed by machinists and toolroom technicians in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is configured for left-hand cut with a -3 degree lead angle and a negative rake geometry, which is standard for harder workpiece materials and interrupted cuts. The Kenloc clamping system provides secure insert seating under high cutting forces. The back-of-bar to cutting edge measurement is 1 inch (25.40 mm) and the center-to-cutting-edge dimension is 1.000 inch. The coolant-through design supports chip evacuation in deep-bore applications. Typical applications include precision bore finishing and roughing in steel, cast iron, and similar materials on horizontal or vertical turning centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA-MDUN toolholder style in the Kenloc series with screw and clamp insert holding\u003c\/li\u003e\n  \u003cli\u003eAccepts DN-style inserts with 1\/2-inch inscribed circle and 3\/16-inch insert thickness\u003c\/li\u003e\n  \u003cli\u003eNegative rake geometry at 5 degrees for stability in demanding cuts\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design with 1\/4-18 NPT threaded coolant port\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cut configuration with -3 degree lead angle\u003c\/li\u003e\n  \u003cli\u003eSteel construction for rigidity across a wide range of boring diameters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with DN-style indexable inserts with a 1\/2-inch inscribed circle and 3\/16-inch thickness, as specified for the Kenloc toolholder system.

Ensure the machine spindle is fully stopped and all energy sources are locked out before mounting or adjusting the boring bar. Verify that the insert is properly seated and the clamping screw or clamp is torqued according to the insert manufacturer guidelines before cutting. Connect the coolant-through port to the machine tool coolant supply using fittings compatible with the 1\/4-18 NPT thread.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.705 inches (43.31 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-1\/4 inches (31.75 mm)\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\u003eHand of Cut\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -3 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\u003eInsert Compatibility\u003c\/strong\u003e: DN style\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: Screw and Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-MDUN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenloc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 1.000 inch\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: 4.57 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: KENNAMETAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1096458\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51747905634610,"sku":"1096458","price":653.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0760dffb405526f335a65b01c2925dbb.jpg?v=1788886918","url":"https:\/\/voomisupply.com\/products\/kennametal-1096458-indexable-boring-bar-1-1-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
