It handles a minimum bore diameter of 0.100 inches and a maximum bore depth of 0.625 inches, making it well suited for tight, precise internal turning operations where rigidity and tool life are critical. The 1\/8-inch shank diameter and 2.0-inch overall length keep the profile compact for small-bore work. Machinists and CNC operators working in job shops, tool rooms, and production environments will find this bar effective on ferrous and hardened materials where conventional high-speed steel tooling falls short.\u003c\/p\u003e\n\u003cp\u003eThis boring bar targets small-diameter internal bores in precision machining applications. It is appropriate for use on CNC lathes, manual lathes, and mill-turn centers where bore tolerances are tight and surface finish requirements are demanding. The helical flute geometry and AlTiN+ coating support dry or minimal-lubrication cutting strategies commonly used in high-speed finishing passes on steel, stainless, and cast iron.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSubmicron-grade solid carbide construction for superior hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ finish coating extends tool life in high-temperature cutting conditions\u003c\/li\u003e\n  \u003cli\u003eHelical boring bar geometry provides improved chip evacuation in confined bores\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard lathe and turning center setups\u003c\/li\u003e\n  \u003cli\u003e0.100 inch minimum bore diameter enables access to very small internal features\u003c\/li\u003e\n  \u003cli\u003eCompact 1\/8 inch shank diameter fits standard small-bore tool holders and collet chucks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling solution for small-bore internal turning applications requiring a 1\/8-inch shank helical boring bar with right-hand cut geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist familiar with lathe or turning center tooling procedures. Ensure the machine spindle is fully stopped and the machine is in a safe lockout state before mounting or adjusting any tooling. Secure the shank firmly in a compatible tool holder or collet to the holder manufacturer's specified clamping procedure to prevent bar deflection during cutting. Verify bore depth clearance against the 0.625-inch maximum depth rating before beginning any machining pass.\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: 0.100 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 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\u003eFinish Coating\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: HB100LFA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52095332188466,"sku":"HB100LFA","price":54.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fad954ce905a01b55eca67506293ef69.jpg?v=1790065754","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-hb100lfa-helical-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
