Machined from submicron-grade solid carbide, it delivers the rigidity and edge retention needed for tight-tolerance work in hardened materials and difficult-to-machine alloys. The right-hand cutting geometry suits standard CNC and manual lathe setups. With a minimum bore diameter of 0.105 inches and a maximum bore depth of 0.375 inches, the BB103 covers a range of small-bore applications where surface finish and dimensional accuracy are the primary objectives. The 0.125-inch shank diameter and 1.5-inch overall length make it compatible with standard small-bore toolholders.\u003c\/p\u003e\n\u003cp\u003eThis boring bar is used in precision machining environments including job shops, production facilities, and tool rooms. It is suited for turning centers, manual lathes, and Swiss-type machines working on small-diameter internal features in components such as medical parts, hydraulic fittings, and instrumentation hardware. The uncoated carbide finish makes it particularly effective for non-ferrous metals, plastics, and other materials where coating buildup could affect dimensional control. A licensed machinist or CNC operator is the typical end user for this tooling.\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\u003eRadial relief geometry reduces cutting forces and improves bore surface finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction compatible with standard lathe and turning center setups\u003c\/li\u003e\n  \u003cli\u003e0.105-inch minimum bore diameter enables work on very small internal features\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suited for non-ferrous materials and applications requiring tight dimensional tolerances\u003c\/li\u003e\n  \u003cli\u003eCompact 1.5-inch overall length fits standard small-bore toolholding systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct tooling option for standard 0.125-inch shank boring bar holders used in small-bore internal turning applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the machine is placed in an e-stop or locked-out state before changing tooling. Secure the shank firmly in the toolholder to the holder manufacturer's specified clamping method, and verify runout before taking a cut. Avoid excessive overhang beyond the rated bore depth, as solid carbide bars are brittle and susceptible to breakage under bending loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Radial Relief\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: 0.105 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 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: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0625 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: SCIENTIFIC CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: BB103\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCIENTIFIC CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51973172724018,"sku":"BB103","price":36.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8175a31f9d324efdb36c38bfbd0fe7c.jpg?v=1789972279","url":"https:\/\/voomisupply.com\/products\/scientific-cutting-tools-bb103-radial-relief-boring-bar","provider":"Voomi Supply","version":"1.0","type":"link"}
