Built from steel with a 1-1\/4 inch shank diameter and a 14 inch overall length, it accommodates TN-style inserts secured by screw or clamp. The minimum bore diameter is 1.47 inches, and the bar features through-coolant capability via a 1\/4-18 NPT coolant hole thread, keeping the cutting zone clear during deep-bore operations. A negative rake angle of 5 degrees and a 0-degree lead angle suit general-purpose internal turning where stable, consistent chip formation matters. Licensed machinists and CNC operators are the primary installers of this toolholder.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for job shops, production machining cells, and toolrooms handling steel, cast iron, and similar materials that call for a negative-rake insert geometry. The 14 inch OAL makes it appropriate for moderate-depth bores where rigidity and reach must be balanced. The through-coolant feature is especially useful in blind-bore or interrupted-cut applications where chip evacuation and heat management are critical. Insert size is defined by a 3\/8 inch inscribed circle and 3\/16 inch thickness, both standard dimensions in the TN-style family.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eA-MTFN toolholder style accepts TN-style inserts with screw or clamp holding method\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant delivery via 1\/4-18 NPT port for improved chip evacuation and tool life\u003c\/li\u003e\n  \u003cli\u003e1.47 inch minimum bore diameter with 1-1\/4 inch shank for rigid setup\u003c\/li\u003e\n  \u003cli\u003e14 inch overall length for moderate-depth internal turning reach\u003c\/li\u003e\n  \u003cli\u003eNegative rake (5 degrees) and 0-degree lead angle for stable general-purpose cutting\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production and toolroom environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept TN-style indexable inserts with a 3\/8 inch inscribed circle and 3\/16 inch thickness.

The machine spindle must be fully stopped and all energy isolated before mounting or adjusting the boring bar in the toolholder block. Verify shank-to-bore clearance and confirm the coolant port connection is properly sealed before engaging through-coolant flow. Follow the machine tool manufacturer guidelines and applicable shop safety standards when setting tool offsets and insert torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.47 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-MTFN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TN style\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 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 or 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\u003eLead Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.765 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.765 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: 2.5 pounds\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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000054\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749254332722,"sku":"7000054","price":730.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e46002e417aec3dcb148ad529707cb6c_11184226-55c0-451a-b0a6-f562d9d2b8f3.jpg?v=1788903645","url":"https:\/\/voomisupply.com\/products\/hertel-7000054-indexable-boring-bar-1-47in-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
