Built to the HBBC toolholder style, it accepts CD-style inserts secured by a screw-clamp holding method, providing repeatable insert positioning and reliable cutting performance. The bar features a 3\/8-inch shank diameter and an overall length of 2.5 inches, making it suited for compact tooling setups. It supports a minimum bore diameter of 0.208 inches and a maximum bore depth of 0.5 inches. Coolant-through capability helps evacuate chips and manage heat at the cutting zone, extending insert life in continuous or interrupted bore applications.\u003c\/p\u003e\u003cp\u003eThis boring bar is used in precision machining environments where small-diameter internal bores require consistent dimensional accuracy. It is a right-hand cut tool, intended for conventional lathe rotation and standard bore entry orientations. Typical applications include finish boring, light roughing, and feature preparation in small-diameter workpieces across production and job-shop settings. Machinists and CNC operators working with ferrous and non-ferrous materials will find the steel body and screw-clamp insert system well suited to stable, low-vibration setups in tight bore geometries.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHBBC toolholder style with screw-clamp insert retention for secure, repeatable seating\u003c\/li\u003e\n\u003cli\u003eAccepts CD-style indexable inserts for flexible cutting geometry options\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.208 inches enables work in tight, small-diameter bores\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 0.5 inches suits shallow to moderate internal features\u003c\/li\u003e\n\u003cli\u003eCoolant-through design directs fluid to the cutting zone for chip control and heat management\u003c\/li\u003e\n\u003cli\u003eRight-hand cut orientation for standard lathe and CNC turning center setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned to accept CD-style indexable inserts.

Ensure the machine spindle is fully stopped and the tool turret or holder is locked out before mounting or changing the boring bar. Secure the shank in a compatible 3\/8-inch boring bar holder or turret block, confirming full engagement and proper overhang to minimize deflection. Follow the insert manufacturer torque guidance for the clamping screw and inspect the insert seat for chips or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HBBC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.208 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches (3\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 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: CD.. style inserts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\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: 3.25 x 0.5 x 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 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: H59868166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51727288074546,"sku":"H59868166","price":216.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/818ed0731c4ee1a42f247305a1c1be24.jpg?v=1788675920","url":"https:\/\/voomisupply.com\/products\/hertel-h59868166-indexable-boring-bar-right-hand-3-8-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
