Constructed from steel, this Kenloc-series bar features a 44.7 mm (1.76 inch) minimum bore diameter and a 38.1 mm (1-1\/2 inch) shank diameter, with an overall length of 355.6 mm (14 inches). The tool accepts TN.. insert geometry and uses a screw-and-clamp insert holding method with a negative 5-degree rake angle. Through-coolant capability is supported via a 1\/4-18 NPT coolant hole thread, keeping cutting zones clear and extending insert life during deep-bore operations.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for CNC turning centers and manual lathes performing internal diameter machining where consistent bore quality and insert security are required. Its 22.61 mm back-of-bar to cutting edge measurement and 0.89 inch center-to-cutting-edge dimension support accurate tool offset setup. The A-MTFN holder style and 1\/2-inch inscribed circle insert compatibility make it a standard fit in shops running medium-to-large diameter boring work on steel, cast iron, and similar workpiece materials. It is installed by machinists and CNC tooling specialists in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand A-MTFN toolholder style for internal boring operations\u003c\/li\u003e\n\u003cli\u003e44.7 mm minimum bore diameter suits medium-to-large bore applications\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design with 1\/4-18 NPT coolant hole for chip evacuation and heat control\u003c\/li\u003e\n\u003cli\u003eScrew and clamp insert holding method provides rigid insert retention\u003c\/li\u003e\n\u003cli\u003eNegative 5-degree rake angle compatible with TN.. series inserts at 1\/2-inch inscribed circle\u003c\/li\u003e\n\u003cli\u003eSteel construction in the Kennametal Kenloc series for rigidity and durability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TN.. style inserts at a 1\/2-inch inscribed circle and 3\/16-inch insert thickness, following the A-MTFN toolholder standard for right-hand boring applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis boring bar should be installed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool turret or holder is de-energized before mounting or removing the bar. Verify shank clamping torque and coolant line connection to the 1\/4-18 NPT port before operation. Consult the machine tool manufacturer's guidelines and relevant shop safety procedures when setting tool offsets and confirming minimum bore clearance.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 44.7 mm (1.76 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 38.1 mm (1-1\/2 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 355.6 mm (14 inches)\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-MTFN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TN..\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\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\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 22.61 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.89 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\u003eSeries\u003c\/strong\u003e: Kenloc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.777 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: 1096389\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51728474177842,"sku":"1096389","price":652.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da31314446462c68022b1dddf9840870.jpg?v=1788691792","url":"https:\/\/voomisupply.com\/products\/kennametal-1096389-indexable-boring-bar-44-7mm-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
