Built from steel with a 5\/8 inch shank diameter and 10 inch overall length, this bar accepts CP.. 32.52 style inserts secured by screw clamping. The minimum bore diameter is 0.77 inches, making it suitable for tight-bore applications where precision and rigidity are critical. A through-coolant design with a 1\/8-27 NPT coolant hole thread delivers cutting fluid directly to the insert tip, extending tool life and improving chip evacuation in deep-bore operations. The neutral rake geometry with a 0 degree rake angle and negative 5 degree lead angle provides stable, predictable cutting performance across a range of steel and ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is intended for use on CNC lathes, turning centers, and manual engine lathes in job shop, production machining, and maintenance environments. It is suited for internal diameter finishing and semi-finishing passes where consistent bore geometry and surface finish are required. The screw-clamping insert holding method allows for quick insert indexing without disturbing the bar setup, reducing downtime between cutting passes. Machinists working with small-bore components in steel or similar ferrous alloys will find this tool well-matched to standard production turning cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMinimum bore diameter of 0.77 inches for small-bore internal turning applications\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant capability via 1\/8-27 NPT threaded coolant port for direct insert cooling and chip flushing\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method for secure, repeatable insert indexing\u003c\/li\u003e\n  \u003cli\u003eAccepts CP.. 32.52 inserts with 3\/8 inch inscribed circle and 5\/32 inch thickness\u003c\/li\u003e\n  \u003cli\u003eNeutral rake, negative 5 degree lead angle geometry for stable cutting and controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eSteel construction with 5\/8 inch shank diameter and 10 inch overall length for rigidity in reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CP.. 32.52 style indexable inserts with a 3\/8 inch inscribed circle and 5\/32 inch insert thickness.

Secure the shank fully in the toolholder block and minimize bar overhang to reduce vibration and deflection during cuts. Shut down the machine spindle and isolate machine power before changing inserts or adjusting the bar position. Verify coolant line connections to the 1\/8-27 NPT port are leak-free before initiating through-coolant flow.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.77 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches (5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: A-SCLP\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: CP.. 32.52\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: 5\/32 inch\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: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: -5 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.406 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\/8-27 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: 0.88 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: 7000039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51751023083826,"sku":"7000039","price":313.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e48f084e57861890a4e11d40b68653d.jpg?v=1788921205","url":"https:\/\/voomisupply.com\/products\/hertel-7000039-indexable-boring-bar-0-77-in-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
