It accepts TPGX 73.. triangular inserts held by screw clamping, delivering positive rake geometry for clean, low-force cuts in small-bore applications. The bar features through-coolant delivery, directing fluid directly to the cutting zone to extend insert life and aid chip evacuation. With an 8mm minimum bore diameter and a maximum bore depth of 59.99mm, it is suited to tight, deep-bore work where tool clearance and rigidity are critical.\u003c\/p\u003e\u003cp\u003eThis boring bar is intended for use in precision metal-cutting environments, including aerospace, automotive, and general machining shops running small-bore internal turning operations. It is compatible with IHAXF-E style toolholders and TPGX 73.. inserts, making it a direct fit for shops already running tooling in that insert family. The 3-degree lead angle supports fine surface finish requirements. Licensed machinists and CNC operators working with ISO-compliant tooling systems will find this bar integrates directly into existing setups built around the Itsbore series.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e8mm minimum bore diameter with a 10.01mm maximum bore diameter for tight-tolerance internal turning\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 59.99mm (2.362 inches) for deep-bore reach\u003c\/li\u003e\n\u003cli\u003eThrough-coolant design directs coolant to the cutting edge, reducing heat and improving chip control\u003c\/li\u003e\n\u003cli\u003ePositive rake cutting geometry reduces cutting forces and tool pressure\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding provides rigid, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 13399 tooling data standards for compatibility with CAM and tool management systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TPGX 73.. triangular inserts and IHAXF-E style toolholders within the ISCAR Itsbore series.

Ensure the machine spindle is fully stopped and the turret is in a safe index position before mounting or removing the bar. Confirm through-coolant passages are clear and the coolant supply pressure matches the machine tool specification before running. Follow the insert manufacturer torque recommendations for the screw-clamp when seating TPGX inserts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 8mm (0.315 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Diameter\u003c\/strong\u003e: 10.01mm (0.394 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 59.99mm (2.362 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 81.99mm (3.228 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16mm (0.630 inches \/ 5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TPGX 73..\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: IHAXF-E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Itsbore\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.225 pounds\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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 4550981\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51745818149170,"sku":"4550981","price":1046.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/882f404709d0dc5b7dfc09faee0e945e.jpg?v=1788865305","url":"https:\/\/voomisupply.com\/products\/iscar-4550981-indexable-boring-bar-8mm-bore-ihaxf-e","provider":"Voomi Supply","version":"1.0","type":"link"}
