Built to the HBBQ toolholder style, it accepts TPC-style inserts secured by a screw-clamp holding method, providing repeatable insert location and reliable cutting forces during deep-bore applications. With a minimum bore diameter of 0.563 inches and a maximum bore depth of 5 inches, this bar handles demanding small-bore work where rigidity and dimensional accuracy are critical. A coolant-through design delivers cutting fluid directly to the cutting zone, extending insert life and aiding chip evacuation.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is suited for shop environments running precision small-bore work in steel, stainless, cast iron, and similar materials on production or job-shop lathes. The right-hand cut orientation and 0.5-inch round shank fit standard boring bar holders and turret tooling blocks. With an overall length of 8 inches and a solid carbide body, it provides the stiffness necessary to minimize chatter at extended reach-to-diameter ratios. Machinists and CNC programmers working tight bore tolerances in production runs will find the consistent insert seating and coolant-through capability directly beneficial.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide body resists deflection and chatter at extended boring depths\u003c\/li\u003e\n  \u003cli\u003eCoolant-through design delivers fluid directly to the cutting edge for improved chip evacuation and insert life\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp insert holding method ensures repeatable insert indexing and secure clamping\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.563 inches with maximum bore depth of 5 inches\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut orientation for standard CNC lathe and turning center setups\u003c\/li\u003e\n  \u003cli\u003eAccepts TPC-style indexable inserts for broad grade and geometry selection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with TPC-style indexable inserts.

Confirm shank clamping torque follows your toolholder manufacturer specifications, and verify boring bar overhang does not exceed recommended length-to-diameter ratios for the material being cut. Ensure the coolant-through supply port is clear and the machine coolant system is compatible with the bar inlet before running. Always inspect the insert seat and clamping screw condition prior to indexing or replacing inserts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: HBBQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.563 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 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: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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: TPC style\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\u003ePackage Dimensions\u003c\/strong\u003e: 8.25 inches L x 0.75 inches W x 0.75 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 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: H59870188\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749428625714,"sku":"H59870188","price":603.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2448604b6c4e1f742954748ad926e80.jpg?v=1788905977","url":"https:\/\/voomisupply.com\/products\/hertel-h59870188-indexable-boring-bar-0-563-in-min-bore","provider":"Voomi Supply","version":"1.0","type":"link"}
