Built on the HBBS toolholder style, it features a 3\/4 inch shank diameter and an overall length of 10 inches. The minimum bore diameter is 0.855 inches, with a maximum bore depth of 8 inches. The insert is secured by a screw-clamp holding method, providing rigid, repeatable positioning under cutting loads. Coolant-through capability is included, supporting chip evacuation and tool life in deep-bore applications. This bar is installed and set up by machinists and toolroom technicians working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis boring bar suits right-hand cut internal operations where tight bore tolerances and surface finish are required. Its solid carbide construction provides the stiffness needed for deep reach relative to bore diameter, reducing chatter in finish and semi-finish passes. It is appropriate for use on CNC turning centers and horizontal machining centers handling ferrous and non-ferrous workpieces. The HBBS-C750R5-10.0-855 configuration is suited to applications requiring a compact entry diameter with extended reach depth.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide body for maximum rigidity and vibration resistance in deep-bore cuts\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.855 inches with maximum bore depth of 8 inches\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard CNC turning setups\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip evacuation and extends insert life\u003c\/li\u003e\n\u003cli\u003eCompatible with TD and TP series insert families\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eAccepts TD and TP series indexable inserts as specified by the manufacturer.

Secure the shank fully within the tool block or boring bar holder to the depth recommended by the machine manufacturer before initiating a cut. Ensure the machine spindle is fully stopped and the control is in an E-stop or locked-out state before changing inserts or adjusting the bar position. Do not exceed the maximum bore depth of 8 inches or operate beyond the insert manufacturer's recommended cutting parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HBBS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.855 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (3\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Cut\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: TD, TP series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 10.25 inches L x 1 inch W x 1 inch H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: H59870691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51747512254770,"sku":"H59870691","price":1303.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/be8e7df571d0e8fe05ebbc7484457b06.jpg?v=1788881642","url":"https:\/\/voomisupply.com\/products\/hertel-h59870691-indexable-boring-bar-0-855in-rh-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
