Machined from submicron-grade solid carbide, this tool delivers the rigidity and edge retention required for small-diameter bores where deflection and chatter control are critical. It features a right-hand cutting direction, a minimum bore diameter of 0.15 inches, and a maximum bore depth of 1 inch. With a 3\/16-inch shank diameter and a 2-inch overall length, this bar fits standard boring bar holders used on CNC lathes and manual turning centers. Machinists and toolroom professionals working with precision components rely on this bar for consistent finish quality in small-bore work.\u003c\/p\u003e\n\u003cp\u003eThis helical boring bar is suited for internal diameter finishing and semi-finishing passes in ferrous and non-ferrous materials where bore access is limited. The submicron carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades, making it appropriate for production environments requiring repeatable dimensional accuracy. The HB1 series is typically applied in aerospace, medical device, and precision component manufacturing where tight tolerances on small internal diameters are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for superior hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eMinimum bore diameter of 0.15 inches enables access to very small internal features\u003c\/li\u003e\n  \u003cli\u003eMaximum bore depth of 1 inch suits a wide range of shallow to moderate bore depths\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard lathe spindle rotation\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch shank diameter fits common small-bore tool holders and turret blocks\u003c\/li\u003e\n  \u003cli\u003e2-inch overall length provides adequate stick-out clearance while maintaining rigidity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC lathes and manual turning centers equipped with boring bar holders accepting a 3\/16-inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered off and the spindle fully stopped before mounting or adjusting the boring bar. Secure the shank firmly in the tool holder to the recommended clamping depth to minimize overhang and reduce vibration during the cut. Verify bore depth clearance before initiating the first pass to avoid tool or workpiece contact outside the intended cutting zone. Follow all applicable shop safety procedures and machine manufacturer guidelines when setting tool offsets.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HB1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241601\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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: HB1501000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52047363080498,"sku":"HB1501000","price":39.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bd1081b90042ad8b63698505b246f9ae_41d4ab6e-5c25-4a6e-b75c-927f12a2770f.jpg?v=1790031877","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-hb1501000-helical-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
