Built with a steel shank measuring 3\/4 inch in diameter and 7 inches in overall length, this bar accepts diamond-shaped inserts held by screw clamping for repeatable, secure positioning. The 95-degree lead angle and negative radial\/neutral axial rake geometry make it well-suited for general-purpose finish and semi-finish boring applications. A minimum bore diameter of 1 inch and a maximum bore depth of 1.438 inches define its working envelope. Coolant-through capability supports chip evacuation and heat management in deep-bore conditions.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for use in production and job-shop turning environments where consistent bore quality is required. The SCLCL\/SCLCR toolholder style accommodates left-hand and right-hand configurations. Compatible insert size code 32.5 with a 3\/8 inch inscribed circle and 0.156 inch thickness narrows insert selection to standard CCMT\/CCGT diamond-style grades. Typical applications include roughing and finishing bores in steel, cast iron, and other ferrous materials. This tool is suited for machinists and CNC programmers working in light manufacturing, aerospace component shops, and general metalworking facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoolant-through design for improved chip evacuation and tool life in blind and deep bore conditions\u003c\/li\u003e\n  \u003cli\u003eScrew clamping insert retention for rigid, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003e95-degree lead angle reduces radial cutting forces during entry\u003c\/li\u003e\n  \u003cli\u003eCompatible with diamond-shaped inserts at 3\/8 inch inscribed circle (size code 32.5)\u003c\/li\u003e\n  \u003cli\u003eSteel shank construction provides vibration damping at moderate overhang ratios\u003c\/li\u003e\n  \u003cli\u003eSCLCL\/SCLCR style supports both left-hand and right-hand boring configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with diamond-shaped inserts with a 3\/8 inch (0.375 inch) inscribed circle, 0.156 inch thickness, and compatible insert size code 32.5, in SCLCL and SCLCR toolholder configurations.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the boring bar from the turret or tool block. Verify coolant-through connections are properly seated before engaging the coolant system. Follow the machine tool manufacturer's torque specifications when clamping the shank and seating the insert screw.\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 95 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Thickness\u003c\/strong\u003e: 0.156 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Insert Size Code\u003c\/strong\u003e: 32.5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw Clamping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative (Radial), Neutral (Axial)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.594 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SCLCL \/ SCLCR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Tool Application\u003c\/strong\u003e: Boring, Turning\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: StreamJetBar\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.833 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: TUNGALOY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6862394\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51959410426162,"sku":"6862394","price":328.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/93de6f61b1e050010ae3f7ff87347efa.jpg?v=1789945679","url":"https:\/\/voomisupply.com\/products\/tungaloy-6862394-indexable-boring-bar-1-in-bore-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
