Built to the HBBS toolholder style, it accepts TD and TP series indexable inserts secured by a screw clamping method. The bar has a 0.668-inch minimum bore diameter, a 0.5-inch shank diameter, and an overall length of 6 inches. Coolant-through capability supports chip evacuation and tool life in production boring operations. Machinists and toolroom technicians use this type of toolholder when a reliable, repeatable insert platform is required for finish or semi-finish boring work.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for use on CNC lathes, manual engine lathes, and turning centers in job shop and production environments. Its right-hand cut orientation makes it the standard choice for conventional spindle-rotation boring on a majority of horizontal turning setups. The maximum bore depth of 4.5 inches allows it to reach through moderate-depth bores without requiring an extended-reach variant. It is a single-purpose toolholder and is not configured as a multi-use tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHBBS toolholder style with screw-clamp insert holding for positive, repeatable insert seating\u003c\/li\u003e\n\u003cli\u003eAccepts TD and TP series indexable inserts\u003c\/li\u003e\n\u003cli\u003e0.668 inches minimum bore diameter with up to 4.5 inches maximum bore depth\u003c\/li\u003e\n\u003cli\u003eCoolant-through design for improved chip control and insert cooling\u003c\/li\u003e\n\u003cli\u003eSteel body construction for rigidity in standard boring applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for conventional spindle-rotation turning setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with TD and TP series indexable inserts.

Confirm shank diameter matches the toolholder bore of the turret or tool block before mounting. Torque the insert clamping screw to the insert manufacturer specification using the appropriate torque key. Verify coolant-through port alignment with the machine turret coolant supply before engaging coolant flow.\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: 0.668 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\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: TD, TP series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\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\u003ePackage Dimensions\u003c\/strong\u003e: 6.25 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: H59870451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51736702812466,"sku":"H59870451","price":168.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/410962a1dc0bea8e7ecdfd239592f960.jpg?v=1788779453","url":"https:\/\/voomisupply.com\/products\/hertel-h59870451-indexable-boring-bar-0-668-in-right-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
