Built from steel, this right-hand holder accepts CN-style inserts secured by screw or clamp clamping, delivering a negative 5-degree rake angle suited for stable, controlled metal removal. The shank measures 1 inch in diameter with an overall length of 12 inches, and minimum bore diameter capability of 1.2 inches (30.48 mm). Coolant-through capability via a 1\/4-18 NPT coolant hole thread supports chip evacuation and tool life in demanding cuts. Licensed machinists and CNC operators specify this bar for precision bore finishing and roughing where insert rigidity and repeatability are required.\u003c\/p\u003e\u003cp\u003eThis boring bar fits standard machine tool turrets and boring bar holders accepting a 1-inch round shank. It is appropriate for steel, cast iron, and similar workpiece materials where CN-style inserts — with a 1\/2-inch inscribed circle and 3\/16-inch thickness — are preferred. The Kenloc clamping system is a recognized platform in production turning environments, including job shops and high-volume manufacturing cells running medium to large bore diameters starting at 1.2 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKenloc-series A-MCLN toolholder style for rigid, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard OD and ID turning setups\u003c\/li\u003e\n\u003cli\u003eScrew and clamp insert holding for secure CN-style insert retention\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with 1\/4-18 NPT threaded coolant port\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry for strength and edge stability on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability across continuous and interrupted cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CN..

Secure the 1-inch shank in the toolholder to the machine manufacturer's specified clamping requirements. Verify coolant-through connections are properly fitted and free of leaks before resuming spindle operation. Always follow applicable shop safety procedures and machine tool manufacturer guidelines when changing tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-MCLN (A16TMCLNR4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Kenloc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 12 inches (304.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.2 inches (30.48 mm)\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\u003eInsert Compatibility\u003c\/strong\u003e: CN..\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\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 16.26 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.64 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: 2.29 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: 1016456\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727464792370,"sku":"1016456","price":437.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c6a7e58d0fe121c3405487520ad671a.jpg?v=1788678213","url":"https:\/\/voomisupply.com\/products\/kennametal-1016456-indexable-boring-bar-1-in-shank-rh","provider":"Voomi Supply","version":"1.0","type":"link"}
