Built to CSBI toolholder style standards, it uses screw-clamped CDC inserts and features a neutral rake angle, which makes it suitable for a wide range of workpiece materials. The steel shank measures 3\/16 inches in diameter with an overall length of 2.5 inches. Minimum bore diameter starts at 0.18 inches, and maximum bore depth reaches 0.5 inches. Coolant-through capability supports chip evacuation in deep or tight-tolerance bores. Machinists and toolroom technicians working in precision turning applications will find this bar straightforward to set up and index.\u003c\/p\u003e\u003cp\u003eThis boring bar fits applications where small-diameter internal features require consistent, repeatable results. It is suited for short-run and production turning on steel, aluminum, and similar machinable materials. The 7-degree lead angle geometry helps manage cutting forces in confined bore entries. Coolant-through delivery at 0.04 inches diameter keeps the cutting zone clear during extended passes. It is not a multi-use tool and is intended specifically for single-point boring with compatible CDC inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimum bore diameter of 0.18 inches for small-diameter internal turning\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003eCoolant-through design with 0.04-inch coolant hole for chip control\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eNeutral rake angle (0 degrees) compatible with a broad range of materials\u003c\/li\u003e\n\u003cli\u003eCDC insert compatibility with 0.156-inch inscribed circle and 0.04-inch insert thickness\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CDC-style inserts.

Secure the shank fully in the tool block or boring bar holder before operation, and confirm insert seating and screw torque per the insert manufacturer specification. Power down and lock out the machine spindle before changing inserts or adjusting tool position. Ensure coolant lines are connected and flow is confirmed before engaging the cut when using the coolant-through feature.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: CSBI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: CDC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.095 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 Diameter\u003c\/strong\u003e: 0.04 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\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: A03XSC7DR12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1289016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738288554290,"sku":"1289016","price":207.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13894880f5abd60c2bd14ead5c224602.jpg?v=1788797751","url":"https:\/\/voomisupply.com\/products\/kennametal-1289016-indexable-boring-bar-right-hand-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
